Re: Request for Exemption under Section 333 of the FAA Modernization and Reform 

Act of 2012 and Part 11 of the Federal Aviation Regulations from Certain Provisions of 

14 C.F.R.

Dear Sir or Madam:

Pursuant to Section 333 of the FAA Modernization and Reform Act of 2012 (the Reform 

Act) and 14 C.F.R. Part 11, Antonelli Law files this petition for exemption on behalf of Helios 

Imaging Inc. (“Helios”), an operator of Small Unmanned Aircraft (“UA”) used for scripted, 

closed-set filming for the motion picture and television industries and for the construction 

industry. Specifically, applicant seeks an exemption from the Federal Aviation Regulations 

(“FARs”) listed in Appendices A and B to allow commercial operation of its UA, so long as such 

operations are conducted within and under the conditions outlined herein or as may be 

established by the FAA in a grant of this petition. 

Approval of the exemption for petitioner will allow commercial operation of the Helios 

960, a proprietary design based on the Tarot 960 airframe, for scripted closed-set filming for (1)

the motion picture and television industries; and (2) the construction industry in Class G airspace 

nationwide, or as otherwise prescribed in an Air Traffic Organization (“ATO”) issued COA. The 

UA operations contemplated by this petition, particularly the construction industry proposed use,

are in the public interest because they clearly satisfy the "Four D's" of exemplary uses of UAs: to 

replace work that is dangerous, difficult, dull, or dirty, and at the same time provide an 

equivalent or greater level of safety than alternative manned aircraft operations. The UA covered 

by this petition is a small battery-powered craft, weighing approximately 18 lbs. (8 kg.), 

inclusive of battery and payload. Operation of the UA under the strict conditions proposed below 

will provide an equivalent level of safety, as Congress intended, while still allowing commercial 

operations. Operations using this UA are far safer than conventional operations conducted with 

helicopters and fixed-wing aircraft that weigh thousands of pounds, carry highly flammable fuel, 

and operate in close proximity to the ground, trees, infrastructure, and people. 

Congress directed the FAA to consider seven factors in deciding whether to approve 

Section 333 exemption petitions - size, weight, speed, operational capability, proximity to

I. Publishable Summary

Pursuant to 14 C.F.R. § 11, the following summary is provided for publication in the 

Federal Register, should it be determined that publication is needed:

Applicant seeks an exemption from the following rules: 

14 C.F.R 21(h); 14 C.F.R. 43.7; 14 C.F.R. 43.11; 14 C.F.R. 45.11; 14 C.F.R. 45.27; 

14 C.F.R. 45.29; 14 C.F.R. 61.113; 14 C.F.R. 91.7(a); 14 C.F.R. 91.9(b)(2); 14 

C.F.R. 91.9(c); 14 C.F.R. 91.103(b)(2); 14 C.F.R. 91.105; 14 C.F.R. 91.113(b); 14 

C.F.R. 91.119(c); 14 C.F.R. 91.121; 14 C.F.R. 91.151(a); 14 C.F.R. 91.203(a) and 

(b); 14 C.F.R. 215; 14 C.F.R. 91.403; 14 C.F.R. 91.405(a); 14 C.F.R. 91.407(a)(1); 

14 C.F.R. 409(a)(1) and (a)(2); and 14 C.F.R. 91.417(a) and (b) to operate 

commercially a small unmanned aircraft system (UA) (18 lbs. or less).

Approval of the exemption for petitioner will allow commercial operation of the 

Helios 960, a propriety design, for scripted closed-set filming for (1) the motion 

picture and television industries and (2) the construction industry nationwide in Class 

G airspace nationwide, or as otherwise prescribed in an ATO issued COA. The 

requested exemption should be granted because operation of small UA, weighing 

approximately 18 lbs. (8 kg.), inclusive of battery and payload, conducted in the strict 

conditions outlined below, will provide an equivalent level of safety, while still 

allowing commercial operations. The lightweight aircraft covered by the exemption 

are far safer than conventional operations conducted with helicopters and fixed-wing 

aircraft weighing thousands of pounds and carrying highly flammable fuel, and 

operating in close proximity to the ground, power lines, transmission towers, 

pipelines, and people. The seven factors Congress directed the FAA to consider when 

approving Section 333 exemption petitions - size, weight, speed, operational 

capability, proximity to airports, proximity to populated areas, and operation within 

visual line of sight – each support the request. In particular, the aircraft are small, and 

will operate at slow speeds, and close to the ground in order to more safely and 

efficiently conduct inspections that would otherwise involve a risk of death to the 

inspectors. The substantial increase of safety and decrease of risk to human life, 

coupled with the low risk use of UAs to conduct these operations, weigh heavily in 

favor of granting the exemption.

III. Proposed Operations

A. The UA

The requested exemption will permit petitioner to operate the Helios 960, a proprietary 

design, with a maximum weight of approximately 18 lbs. (8 kg.), inclusive of batteries and 

technical payload. This rotorcraft operates at a speed of no more than 35 knots and has the 

capability to hover and move in the vertical and horizontal planes simultaneously.

The UA will use the following:

 GPS/Autopilot System: DJI WooKong-M, with its accompanying Main Controller (MC), 

Internal Measurement Unit (IMU), and GPS.

 Receiver: Futaba R6014HS 14-Channel 2.4GHz FASST

 Datalink: DJI iOSD Mark II 2.4 Ghz, which displays power voltage, flight velocity, height, 

distance from the home point, horizontal attitude and GPS satellite number acquired to make 

the location calculation.

 Transmitter 1 (Tx1): Futaba 14 MZ, used by the UA operator to control the UA

 Transmitter 2 (Tx2): Futaba 14 SG, used by the camera operator to control the gimbal and 

camera

Please refer to Exhibits 1-12 for further information regarding the UA. Details regarding 

the design and assembly of the UA are being submitted confidentially, due to the proprietary 

nature of the UA. The petition and the supporting documentation in the Exhibits are hereinafter 

referred to as the “operating documents.”

The specific conditions of the proposed exemption that relate to the characteristics of the 

UA are numbers 1, 5, and 16-20 in Section V below. Each has been adopted or imposed by the 

FAA in numerous previous grants of Section 333 exemption petitions. 

B. The Crew

The crew will consist of a pilot in command (PIC), a visual observer (VO), and a camera 

operator (CO).

The PIC, VO, and CO will have been trained in operation of UAs generally. The PIC is a 

lifelong model aircraft hobbyist, with years of general UA experience. Additionally, the PIC will 

have completed, at a minimum, 40 hours of UA flight training with this specific UA prior to 

operations, and will be required to participate in annual training thereafter.

The specific conditions of the proposed exemption that relate to the training and 

characteristics of the crew are numbers 3 and 6-9 in Section V below. Each has been adopted or 
7

imposed by the FAA in numerous previous grants of Section 333 exemption petitions. 

C. Flight Conditions

The UA will be used for scripted closed-set filming for the motion picture and television 

industries and the construction industry. It will be flown in Class G airspace nationwide under 

200 feet above ground level (“AGL”) and under controlled conditions over property that is 

restricted as stated below under D. Flight Operations. Petitioner will work with the local FSDO 

when planning operations. Petitioner will only operate its UA in visual meteorological conditions 

(VMC). The UA will at all times be no less than 500 feet below and no less than 2,000 feet 

horizontally from a cloud, and petitioner will not conduct operations unless visibility is at least 3 

statute miles from the PIC. The flight crew will always make a safety assessment of the risk of 

every operation, and will only operate when it is determined that no hazards are present.

The specific conditions of the proposed exemption that relate to the flight conditions in 

which the UA will be operated are numbers 2, 4, 16, and 28-29 in Section V below. Each has 

been adopted or imposed by the FAA in numerous previous grants of Section 333 exemption 

petitions.

D. Flight Operations

The purpose of every UA flight will be to conduct safe, accurate, and efficient (i) scripted 

closed-set filming for the motion picture and television industries or (ii) site inspections for the 

construction industry in Class G airspace nationwide.

The PIC will be responsible for flying the UA and will use a Futaba 14 MZ transmitter. 

The PIC will have visual contact with the UA at all times and will have available on screen 

display to observe telemetry data, including battery power and flight altitude. The on screen 

display/telemetry information will also be available on an iPad. The main purpose of the iPad 

with the telemetry information is to set an audio signal for when the voltage on the battery is 

running low.

The VO will be responsible for the overall safety of the operation. The VO will observe 

the UA and flight operational area without any display monitors.

The CO will use a Futaba 14SG transmitter to control the gimbal and the camera. The CO 

will use an on screen display monitor to observe the camera data and change what is being 

viewed.

Prior to the day of an operation, the flight crew will conduct a site inspection. The flight 

crew will look for obstructions in the filming or construction area, and determine a safe flight 

plan. The flight crew will also make a note of any public access points in the general area, where 

nonparticipating individuals could access the operational area. The flight crew will adapt their 

flight plan to avoid these areas.

On the day of an operation, the flight crew will cone off the flight operational area (if not 

already roped off), up to 1⁄2 square miles. The only individuals allowed within the flight 

operational area will be participants – actors, crew members, or construction workers. All other 
8

nonparticipating individuals and vehicles will be outside the sectioned-off area. Prior to each 

operation, the flight crew will conduct a safety briefing with all individuals who will be in the 

flight operational area.

The flight crew will set a “home area” that the UA will launch from and return to. The 

area will have a ten-foot radius and be marked off with traffic cones. The flight crew will stand 

outside this area. During operations, the flight crew will wear high visibility safety vests and 

helmets. The three members of the flight crew will stand next to each other and be able to 

communicate orally.

The flight crew will conduct a pre- and post-flight inspection, as laid out in Helios’s 

Inspection Procedures, Exhibit 12. The flight crew will also conduct an inspection flight each 

week, going through both the pre- and post-flight procedures to ensure that the Helios 960 is in a 

safe condition.

In the unlikely event of emergency or a lost link, the UA will be equipped with an 

emergency “return to home” feature as part of the DJI WooKong-M flight control. If there is a 

lost link, the WooKong-M will be programmed to rise 65.6 feet (20 meters) instantaneously (not 

to exceed a maximum altitude of 200 AGL), travel horizontally to the home area, and land. For 

more information regarding the emergency fail safe methods, please refer to the WooKong-M 

User Manual (Exhibit 1) to this petition. The failsafe section begins on page 17 of that document.

Flights will be terminated at 20% of battery life. Currently, the Helios 960’s battery is 

limited to approximately 10 minutes of flight time. Helios will use an iPad to monitor telemetry 

data, including battery life. The iPad will send an audio signal when the battery depletes to 20% 

of remaining power.

The specific conditions of the proposed exemption that relate to flight operations are 

numbers 11-12, 17-25, and 32-35 in Section V below. Each has been accepted or imposed by the 

FAA in numerous previous grants of Section 333 exemption petitions.

IV. Aircraft and Equivalent Level of Safety

Petitioner proposes that the exemption apply to UAs that have the characteristics and that 

operate with the limitations proposed herein. These limitations provide for a level of safety at 

least equivalent to or higher than manned aircraft operations under the current regulatory 

structure. Section V below identifies the limitations and conditions to which petitioner agrees to 

be bound when conducting commercial operations under a grant of this petition. Appendix A

contains a matrix connecting: (i) the specific proposed condition with (ii) the FAR provision for 

which it provides an equivalent level of safety and (iii) one or more recent Section 333 

exemption grants in which the FAA recognized this equivalent level of safety. Appendix B 

requests relief from additional FARs that are not identified in Appendix A.

Approval of the commercial operations outlined in this petition presents no national 

security issue. The PIC is willing to undergo a background check, including the proposed

Transportation Security Administration Vetting process, to ensure that no national security threat 

is present. Operation and Certification of Small Unmanned Aircraft, 80 Fed. Reg. 9543 at 9572

V. Proposed Conditions of the Exemption

1. The UA will weigh approximately 18 lbs. (8 kg.), inclusive of battery and technical payload.

2. UA operations under this exemption will be limited to conducting operations for the purpose 

of scripted closed-set filming for the motion picture and television industries and 

construction site inspections in Class G airspace nationwide.

3. Flights will be operated within line of sight of a pilot and visual observer.

4. Flights will be operated at an altitude of no more than 200 feet AGL, as indicated by the 

procedures specified in the operating documents. All altitudes reported to ATC must be in 

feet AGL.

5. The UA will not be flown at an indicated airspeed exceeding 35 knots.

6. Minimum flight crew for each operation will consist of the UA pilot in command (PIC), a 

visual observer (VO), and a camera operator (CO).

7. The PIC will have, at minimum, 40 hours of training on the UA to be operated under this 

grant before accepting commercial operations.

8. The petitioner will not permit any PIC to operate unless the PIC meets its qualification 

criteria and demonstrates the ability to safely operate the UA in a manner consistent with 

how the UA will be operated under this exemption, including evasive and emergency 

maneuvers and maintaining appropriate distances from persons, vessels, vehicles and 

structures. PIC qualification flight hours and currency will be logged in a manner consistent 

with 14 CFR § 61.51(b). A record of the PIC training will be documented and made available 

upon request by the Administrator. Training operations will only be conducted during 

dedicated training sessions. During training, proficiency, and experience-building flights, all 

persons not essential for flight operations will be considered nonparticipants, and the PIC 

will operate the UA with appropriate distance from nonparticipants in accordance with 14 

CFR § 91.119. 

9. The VO will not perform any other duties beyond assisting the PIC with seeing and avoiding 

other air traffic and other ground based obstacles/obstructions, and will not be permitted to 

operate the camera or other instruments.

10. The PIC will be designated before the flight and will not be allowed to transfer his or her 

designation for the duration of the flight. The PIC will ensure that the VO can perform the 

functions prescribed in these conditions and the operating documents.

11. A briefing will be conducted in regard to the planned UA operations prior to each day’s 

activities. It will be mandatory that all personnel who will be performing duties in connection 

with the operations be present for this briefing. 

12. Prior to each flight, the PIC will inspect the UA, including the Ground Control Station, to 

ensure it is in a condition for safe flight. If the inspection reveals a condition that affects the 
10

safe operation of the UA, the PIC will not operate the UA until the necessary maintenance 

has been performed and the UA is found to be in a condition for safe flight. All maintenance 

and alterations will be properly documented in the aircraft records.

13. Petitioner will conduct a functional flight test on any UA that has undergone maintenance or 

alterations that affect the UA operation or flight characteristics, e.g. replacement of a flight 

critical component. The PIC who conducts the functional test flight will make an entry in the 

aircraft records. 

14. The petitioner will carry out its maintenance, inspections, and record keeping requirements, 

at the direction and under the supervision of the UA manufacturer. Maintenance, inspection, 

alterations, and status of replacement/overhaul component parts will be noted in the aircraft 

records, including total time in service, description of work accomplished, and the signature 

of the manufacturer, authorizing the return of the UA to service. The manufacturer will make 

an entry in the aircraft record of the corrective action taken against discrepancies discovered 

between inspections.

15. When conducting operations for the motion picture and television industry, petitioner will 

submit a written Plan of Activities, and any additional necessary paperwork, to the FSDO at 

least one day before the proposed operations begin.

16. The UA will be operated within visual line of sight (VLOS) of the PIC and VO at all times. 

This requires the PIC to be able to use human vision unaided by any device other than 

corrective lenses. PIC and VO will at all times be able to communicate verbally. They will 

not be permitted to use electronic messaging or texting to communicate during flight 

operations. 

17. The PIC will not begin a flight unless (considering wind and forecast weather conditions) 

there is enough power to fly at normal cruising speed to the intended landing point and land 

the UA with 20% battery power remaining. 

18. Actual total flight time for each operational flight will result in no less than a 20% battery 

reserve.

19. The UA will have the capability to abort a flight in case of unexpected obstacles or 

emergencies. 

20. The UA will be programmed so that if it loses communication with the ground station or 

loses its GPS signal, it will return to a pre-determined location within the planned operating 

area and land or be recovered in accordance with the operating documents

21. If the UA and its radio control link disconnect during flight, the system’s failsafe protection 

will be triggered and the multirotor will return to home and land automatically, rather than 

flying off uncontrollably or landing at an unknown location. 

22. The operating documents required under 14 CFR §§ 91.9 and 91.203 will be maintained and 

available to the PIC at the Ground Control Station of the UA any time the UA is operating. 

These documents will be made available to the Administrator or any law enforcement official 
11

upon request. If a discrepancy exists between the conditions and limitations in the exemption 

grant and the procedures outlined in the operating documents, the grant conditions and 

limitations will take precedence and will be followed. Otherwise, the petitioner will follow 

the procedures outlined in its operating documents. If it updates or revises its operating 

documents, it will present updated and revised documents to the Administrator upon request. 

If the petitioner determines that any update or revision would affect the basis upon which the 

FAA granted the exemption, then the Petitioner will petition for an amendment to the grant 

of exemption. 

23. Petitioner will obtain written and/or oral permission from the landowners/authorized agents 

of the landowners over which flights will be conducted.

24. Petitioner will obtain all required permissions and permits from territorial, state, county or 

city jurisdictions, including local law enforcement, fire, or other appropriate governmental 

agencies. 

25. UA operations will not be conducted during night, as defined in 14 CFR § 1.1. All operations 

will be conducted under visual meteorological conditions (VMC). Flights will not be 

conducted under special visual flight rules (SVFR). 

26. The petitioner will obtain an Air Traffic Organization (ATO) issued Certificate of Waiver or 

Authorization (COA) prior to conducting any operations under the grant of exemption. 

Petitioner will request a Notice to Airman (NOTAM) not more than 72 hours in advance, but 

not less than 48 hours prior to the operation. All operations will be conducted in accordance 

with airspace requirements in the ATO issued COA, including class of airspace, altitude level 

and potential transponder requirements. 

27. The UA will not be operated within 5 nautical miles of an airport reference point as denoted 

on a current FAA-published aeronautical chart unless a letter of agreement with that airport’s 

management has been obtained, and the operation is conducted in accordance with a 

NOTAM as required by the operator’s COA. Any letter of agreement with the airport 

management will be made available to the Administrator upon request. 

28. The UA will not be operated less than 500 feet below, or less than 2,000 feet horizontally 

from, a cloud or when visibility is less than 3 statute miles from the PIC. 

29. All operations shall be conducted in Class G airspace or as otherwise prescribed in an ATO 

issued COA. 

30. All aircraft operated in accordance with this exemption will be identified by serial number, 

registered in accordance with 14 CFR part 47, and have identification (N-Number) markings 

in accordance with 14 CFR part 45, Subpart C. Markings will be as large as practicable. 

31. Before conducting operations, petitioner will ensure that the radio frequency spectrum used 

for operation and control of the UA complies with the Federal Communications Commission 

(FCC) or other appropriate government oversight agency requirements. 

32. The UA will remain clear and yield the right of way to all manned aviation operations and 
12

activities at all times. 

33. The UA will not be operated by the PIC from any moving device or vehicle. 

34. The UA will not be operated over congested or densely populated areas. 

35. Petitioner will conduct all flight operations at least 500 feet from all nonparticipating 

persons, vessels, vehicles, and structures unless one of the following three conditions is met:

a. Barriers or structures are present that sufficiently protect nonparticipating persons from 

the UA and/or debris in the event of an accident. The petitioner will ensure that 

nonparticipating persons remain under such protection. If a situation arises where 

nonparticipating persons leave such protection and are within 500 feet of the UA, the PIC 

will ensure that flight operations cease immediately. 

b. The aircraft is operated near vessels, vehicles or structures where the owner/controller of 

such vessels, vehicles or structures has granted permission and the PIC has made a safety 

assessment of the risk of operating closer to those objects and determined that it does not 

present an undue hazard.

c. Operations nearer to the PIC, VO, operator trainees or essential persons do not present an 

undue hazard to those persons per § 91.119(a).

36. Petitioner will report any incident, accident, or flight operation that transgresses the lateral or 

vertical boundaries of the operational area as defined by the applicable COA to the FAA's 

UAS Integration Office (AFS-80) within 24 hours. Petitioner will report accidents to the 

National Transportation Safety Board (NTSB) per instructions contained on the NTSB Web 

site: www.ntsb.gov.

VI. Privacy

There is little concern that the proposed flights will cause invasions of privacy because all 

flights will occur (i) over public spaces, where there is no expectation of privacy, and around 

participating individuals or (ii) over private, restricted property where applicant has permission 

from the landowner/authorized agent to film. When the UA is being flown, the onboard cameras 

will be focused on the film or inspection area, not on nonparticipating individuals who may be 

present during filming.

VII. Public Interest and Safety

The planned UA use will increase ground safety in both the television and movie 

industry, and the construction industry. The enhanced safety and reduced environmental impact 

achieved using a UA with the specifications described by the petitioner and carrying no 

passengers or crew, rather than a manned aircraft of significantly greater proportions, carrying 

crew in addition to flammable fuel, gives the FAA good cause to find that the UA operation 

enabled by this exemption is in the public interest.

Satisfaction of the criteria provided in Section 333 of the Reform Act of 2012 – size, 
13

weight, speed, operating capabilities, proximity to airports and populated areas and operation 

within visual line of sight and national security – provide more than adequate justification for the

grant of the requested exemption allowing commercial operation of applicant’s UA for filming 

the television and movie industry and the construction industry, pursuant to petitioner’s rules of 

operation.

A. Motion Picture and Television Industry Filming

As the FAA has repeatedly recognized in granting other exemptions under Section 333, 

the use of a UA to take videos and photography over closed, scripted, motion picture and 

television sets significantly increases the level of safety for both the actors and crew. Currently, 

filmmakers use manned aircraft, which can weigh 6,000 lbs. or more. Manned aircraft also, by 

definition, carry a pilot and other crew. They carry flammable fluids, and require large areas to 

take off, operate over, and land.

By using the Helios 960, many of these dangerous conditions will be alleviated. The 

Helios 960 weighs under 15 lbs. The pilot and flight crew will be safely on the ground rather 

than several hundred feet in the air. The UA is powered by a battery, and requires a small area to 

operate in. The FAA has previously determined that using a UA such as the Helios 960 will 

provide a greater level of safety when filming for the motion picture and television industry. 

Exemption No. 11062.

B. Construction Inspections

Use of a UA to conduct inspections of construction projects will provide a greater level 

of safety than what is currently available. The construction industry has traditionally been very 

dangerous for workers, both based on the working conditions and equipment used, including 

helicopters and cranes. Currently, aerial inspections are not done on many construction projects. 

Instead, inspections are conducted from the ground, or from within the structure being 

constructed, giving a limited view of the project. This limits the capabilities of architects and 

construction crews examining the work that has been done, and could lead to misidentification or 

failure to identify flaws in the construction. Those projects that do incorporate aerial inspections 

must rely upon manned helicopters or other types of aircraft, devices that can pose a great risk to 

those piloting and those on the ground below, without providing the most accurate results. 

Alternatively, using the Helios 960 to videotape and photograph construction sites will 

allow the construction crew to gain a better vantage point of the structure. Safety concerns can be 

better identified and fixed, and the inspectors will be able to gain a more thorough understanding 

of construction progress. This UA will be able to provide a quick and cost effective aerial 

inspection of an entire jobsite, something that is much more difficult to perform without this 

technology. The device can be used to check the progress of the project and provide visual 

information on hard-to-reach areas that may not be adequately inspected otherwise without 

putting people in danger. UAs can be equipped with specialized cameras and sensors that 

provide enhanced detection of other concerns, such as gas leaks, lack of structural integrity. The 

FAA has previously determined that using a UA such as the Helios 960 will provide an 

equivalent or greater level of safety than manned flight when inspecting construction sites.

B. Appendix B: Helios’s argument for exemption from 14 C.F.R. §61.113: Private pilot 

privileges and limitations: Pilot in command. 

Helios requests an exemption from 14 C.F.R. §61.113 so that the PIC of the UA will not 

be required to possess a private or commercial pilot’s license. As the FAA and numerous other 

national airspace regulators have recognized, UA operations conducted by persons who do not 

hold a pilot’s license can still achieve the equivalent level of safety of current operations by 

manned aircraft with pilots holding a private or commercial pilot’s license. 

Although it recognizes that a pilot’s license is unnecessary for safe UA operation, the 

FAA has to date declined to allow grant exemptions under Section 333 that would permit 

individuals who possess neither a private nor a commercial pilot’s certificate to conduct 

commercial UA operations. It has specified two reasons for declining to do so. First, it has stated 

that it does not possess the authority under Section 333 to exempt individuals from the 

requirement under 49 U.S.C. §44711 to hold an airman certificate authorizing the airman to 

serve in the capacity for which the certificate was issued. Exemption No. 11110 at 14. Second, 

the FAA has concluded that the Department of Homeland Security (DHS) security screening 

required of all certified airmen meets the statutory requirement in Section 333 that operations not 

pose a threat to national security. Exemption No. 11110 at 15.

Helios respectfully requests that the FAA reconsider its position. There is no dispute that 

it is unnecessary for an operator of a UA to go through the rigorous process of becoming a 

certified pilot in order to safely operate a UA. In addition, the FAA does have the authority to 

exempt UA operators from the requirement in 49 U.S.C. §44711to hold an airman certificate for 

“serv[ing] in the capacity for which the certificate was issued.” Indeed, it has exercised that 

authority repeatedly in the Section 333 process. Finally, the FAA’s security concerns can be 

addressed by a variety of methods involving operator background checks to be conducted by 

government agencies. 

1. The FAA and foreign regulators recognize that obtaining a manned aircraft 

pilot license is unnecessary for safe operation of a UA

The FAA, like the other national airspace regulators that have considered the issue, has 

concluded that UA operations conducted by persons who do not hold a pilot’s license can still 

achieve the equivalent level of safety of current operations by manned aircraft with pilots 

holding a private or commercial pilot’s license. In its recent UAS NPRM, the FAA stated:

“While these airman certification requirements are necessary for manned aircraft 

operations, they impose an unnecessary burden for many small UAS operations. 

This is because a person typically obtains a private or commercial pilot certificate 

by learning how to operate a manned aircraft. Much of that knowledge would not 

be applicable to small UAS operations because a small UAS is operated 

differently than manned aircraft. In addition, the knowledge currently necessary to 

obtain a private or commercial pilot certificate would not equip the certificate 

holder with the tools necessary to safely operate a small UAS... Thus, requiring 

persons wishing to operate a small UAS to obtain a private or commercial pilot 

certificate imposes the cost of certification on those persons, but does not result in 

a significant safety benefit because the process of obtaining the certificate does 
18

not equip those persons with the tools necessary to mitigate the public risk posed 

by small UAS operations.” Operation and Certification of Small Unmanned 

Aircraft, 80 Fed. Reg. 9543 at 9550 (proposed Feb. 23, 2015 (to be codified at 14 

C.F.R. Parts 21, 43, 45, et al.)).

The FAA’s conclusion that manned aircraft flying experience is unnecessary for the 

operation of a UA is supported by research by the FAA and the Army Research Laboratory. 

They demonstrate that UAs, even those much larger than the sUAS proposed by Helios, can be 

safely flown by non-certificated pilots with a small amount of training. For example, one Army

Research Laboratory study concluded: 

"[T]he specific motor skills needed to control the radio-controlled UAV would 

have to be learned by aviators independently of the motor skills learned in flying 

an aircraft. In particular, the somatic and visual cues that pilots use during aircraft 

landings would not be useful (and perhaps even counter-productive) for the 

different skill sets and perceptual viewpoint necessary for radio-controlled 

landings.”1

Additional research reports lend further support for the exclusion requested. For example, a 

report sponsored by the FAA concluded that "We know that certain systems, like the U.S. Army 

Hunter and Shadow systems, are successfully flown by pilots with no manned aircraft 

experience."2

In addition, foreign government airspace regulators that have examined the issue have 

consistently recognized that the skills required to fly a manned aircraft are irrelevant to operating 

a UA. For that reason, they have concluded that UA operators do not need to have a private or 

commercial pilot’s license. Canada, for example, does not require a pilot’s license to operate a 

UA. Transport Canada requires training of UA operators, but that training is limited to pilot 

ground school and flight operation training on UAs, not manned aircraft.3 Moreover, Canada 

allows this training to be “provided by other pilots, manufacturers, [UA] flight training

organizations or . . . self taught.” 4

Similarly, the United Kingdom’s Civil Aviation Authority (CAA) recognized that 

determining “Remote Pilot qualification requirements on the same basis as manned aircraft may 

yield requirements that are too inflexible, too onerous and inappropriate for UAS operations.”5 

As a result, the CAA only requires UA operators to demonstrate UA operator competence.6

While there are a variety of ways to demonstrate competence, the most common is to complete a 

course that will lead to a ground exam and flight test. Australia, too, requires only passage of a 

UA-specific ground school program in lieu of a private pilot license.7 Finally, more than a dozen 

countries, including Germany, Italy, France, Spain and the Netherlands, have adopted the 

National UAS Certificate for Small Unmanned Aircraft (BNUC-S) Standard for UA pilot 

certification.8 This standard results in a type-specific UA certificate and does not require the 

operator to have a pilot’s license. The process involves taking a short ground school course, 

passing a ground school test and then passing a practical test on commercial operation of the 

specific UAS per the UAS manufacturer’s operations manual. 

All of this experience and evidence indicates that the proposed exemption will provide a 

greater level of safety than operations under 14 C.F.R. §61.113. In this instance, the PIC has had 

decades of UA experience. He has focused his training and education on UAs generally, and in 

particular on the aircraft to be operated, rather than taking additional time and risk to train on a 

manned aircraft, weighing several thousand pounds and carrying highly flammable fuel.

The FAA has concluded in the NPRM that such UA-specific training is more than 

sufficient to provide an equivalent level of safety for UA operations. Sometime in the next 18-

24 months, that position will be enshrined in a valid regulation. However, in the meantime, the 

FAA claims it lacks the authority to relax the requirement to possess a pilot certificate. As we 

show in the next section, that position is both incorrect and contradicted by the FAA’s recent 

decisions.

2. The FAA has and has already exercised the authority to exempt applicants from 

the airman certificate requirement

The FAA claims that it lacks authority to exempt UA operators from the requirement of 

49 U.S. §44711 to hold an airman certificate authorizing the airman “to serve in the capacity for 

which the certificate was issued.” See, e.g., Exemption No. 11110 at 14. This claim is 

inconsistent with both (i) the statutory language of that section and Section 333, and (ii)

numerous recent FAA decisions.

The operative part of 49 USC §44711 provides that a “person may not . . . serve in any 

capacity as an airman with respect to a civil aircraft, . . . used, or intended for use, in air 

commerce — (A) without an airman certificate authorizing the airman to serve in the capacity 

for which the certificate was issued . . . “ If the FAA’s interpretation were correct, this language 

would require that any person wishing to operate a UA for commercial operations have an 

airman certificate authorizing the person to serve as an airman in commercial operations. 

However, in all of its recent grants of Section 333 petitions, the FAA has – without 

explicitly acknowledging the fact - exempted commercial UA operators from the § 44711(A) 

requirement that they hold an airman certificate authorizing them “to serve in the capacity for 

which the certificate was issued.” It has done so by allowing them to operate a UA so long as 

they hold a private pilot’s or sport pilot’s authorization, even though such a certificate does not 

permit commercial operations. Exemption No. 11062 at 15-18; Exemption No. 11110 at 14-16; 

Exemption No. 11191 at 3-5; and Exemption No. 11229 at 3 and 8.

The FAA argues that it cannot exempt applicants from the requirements of §44711 

because, while the specific language of Section 333 grants it limited statutory flexibility relative 

to 49 U.S.C. §44704 for the purposes of airworthiness certification, Section 333 does not provide 

flexibility relative to §44711 and other sections of Title 49. Exemption No. 11110 at 14. This 

argument ignores the plain language of the statute. The relevant language of Section 333 is:

(a) IN GENERAL.—Notwithstanding any other requirement of this subtitle, and 

not later than 180 days after the date of enactment of this Act, the Secretary of 

Transportation shall determine if certain unmanned aircraft systems may operate 

safely in the national airspace system before completion of the plan and 

rulemaking required by section 332 of this Act or the guidance required by 

section 334 of this Act.

(b) ASSESSMENT OF UNMANNED AIRCRAFT SYSTEMS.—In making the 

determination under subsection (a), the Secretary shall determine, at a 

minimum—

(1) which types of unmanned aircraft systems, if any, as a result of their size, 

weight, speed, operational capability, proximity to airports and populated areas, 

and operation within visual line of sight do not create a hazard to users of the 

national airspace system or the public or pose a threat to national security; and

(2) whether a certificate of waiver, certificate of authorization, or airworthiness 

certification under section 44704 of title 49, United States Code, is required for 

the operation of unmanned aircraft systems identified under paragraph (1).

(c) REQUIREMENTS FOR SAFE OPERATION.—If the Secretary determines 

under this section that certain unmanned aircraft systems may operate safely in 

the national airspace system, the Secretary shall establish requirements for the 

safe operation of such aircraft systems in the national airspace system.
21

The language of Section 333(b) is permissive: it requires that the Secretary “determine, at 

a minimum . . . whether a certificate of waiver, certificate of authorization, or airworthiness 

certification under section 44704 of title 49, United States Code, is required for the operation of 

unmanned aircraft systems identified under paragraph (1).” Nothing in (b) precludes the 

Secretary from determining whether or not a pilot’s license is required for operation of a UA 

identified under paragraph (b)(1).

Indeed, the FAA has implicitly conceded the point by granting exemptions from the 

requirement that commercial UA operators hold a commercial pilot certificate. From an 

analytical standpoint, there is no difference between granting an exemption from the commercial 

pilot’s license requirement and granting an exemption from the private or sport pilot’s license 

requirement. Both are clearly exemptions from a specific statutory requirement in 49 U.S.C. 

§44711. If the FAA has the statutory authority under Section 333(b) to do the former, it has the 

same authority to do the latter.9

For all of the reasons set forth above, the FAA should reconsider its position and exercise 

its full authority to grant an exemption from all the requirements of 49 USC §44711, so that a 

person serving as a commercial UA operator need not have a pilot’s license. 

 

9 The FAA has not specifically identified the statutory provision that underpins its authority to 

grant the exemptions from the commercial pilot’s license requirement. Whether the statutory 

basis is Section 333 or some other provision makes no difference. If there is a basis for a partial 

exemption from in 49 U.S.C. § 44711, that basis also justifies an exemption from the entire 

provision.

Specially designed for WKM to solve the high power consumption problem of the power

 support system. It contains two power outputs for the entire WKM system and receiver

 separately, a battery voltage monitor, and two CAN-Bus interfaces.

Built-In Damper

Small footprint and weight offer ease of installation in tight spaces, for various aircraft

 sizes.

Precise Position And Altitude Hold

With WKM, the multirotors will have position and altitude lock in windy conditions.

 Precise hovering in less than 2m horizontal and 0.5m vertical.

High Accuracy And Driving Handfeel

With the WKM, flying a multi-rotor will be as easy as driving a car. The pilot is released

 from the stress of controlling the multi-rotor and able to pay more attention to other

 tasks such as camera angle, instead of focus on flying.

Motor Arm/Disarm Mode

27
1. Start Motor: When using WKM, pushing throttle stick before takeoff will not start

 motors. You have to execute any one of following four Combination Stick

 Commands (CSC) to start motors.

2. Stop Motor: We provide two options to stop motors: Immediate and Intelligent.

 Immediately Mode: By using this mode, in any control mode, once motors start and

 throttle stick is over 10%, motors will stop immediately when throttle stick is back

 under 10% again. In this case, if you push the throttle stick over 10% in 5 seconds

 after motors stop, motors will re-start, CSC is no needed. If you don’t push throttle

 stick after motors start in three seconds, motors will stop automatically. Intelligent

 Mode: By using this mode, different control modes have different way of stopping

 motors. In Manual Mode, only executing CSC can stop motors. In Atti. or GPS Atti.

 Mode, any one of following four cases will stop motors:

Multiple Flight Control Mode/ Intelligent Switching

GPS Atti. Mode Atti. Mode Manual Mode

Applications AP work Sports flying. —

Point Of Interest (POI)

WooKong-M has a new function: Point of Interest. When the GPS signal is good, users

 can record the present position of the aircraft as a point of interest by the preset switch

 on the remote control. The aircraft could achieve a circle flight around the point of

 interest with the nose in the point in an area of 5 meters to 500 meters radius, when the

 rolling command is given. This function is easy to set up and convenient to operate, it is

 suitable for all-round shooting of a fixed scenic spot.

28
RTH Switch From Transmitter

In addition to the function of failsafe RTH, WooKong-M now has a new function of

 RTH switch from transmitter. It is unnecessary to turn into failsafe mode.

Support IOSD MARK II

The WooKong-M now support iOSD MARK II. This will undoubtedly give you a

 fantastic flight performance. Depending upon DJI’s accumulation of historic and reliable

 information integration technology, the iOSD MARK II can grab the most accurate firsthand flight data information in the shortest possible time.

Intelligent Orientation Control (IOC)

Usually, the forward direction of a flying multi-rotor is the same as the nose direction. By

 using Intelligent Orientation Control (IOC), wherever the nose points, the forward

 direction has nothing to do with nose direction:

In course lock flying, the forward direction is the same as a recorded nose direction. See

 the following figures (Mode 2) In home lock flying, the forward direction is the same

 as the direction from home point to multi-rotor.See the following figures (Mode 2)

Enhanced Fail-Safe And Auto Go Home/Landing

Enhanced fail-safe is the feature to ensure that the multi-rotor will hover automatically if

 it loses RC signal. After losing the signal in a certain time period, WKM will calculate

 the safest way to return the helicopter to the home position. The helicopter will hover

 over your GPS start point and land automatically. This feature will guarantee the safety

 of your expensive payloads and equipments on the platform.

29
Multi-Rotor One-Power Output Fail Protection

In most conditions, the whole multi-rotor will retain good attitude and rotate around the

 frame arm with no power output, due to imbalanced mechanical structure and external

 environment. Rotating is mainly caused by payload and external environment. When

 payload is heavier, rotating speed is faster. On rotating, the hexa-rotor physical structure

 can cause rudder to become out of control. The humanistic protection function from

 WooKong-M, in Attitude or GPS Mode, keeps attitude under control even with any one

 power output failed and highly reduces crash risk.

Two Levels Low Voltage Protections And Auto Go Home

In order to prevent your multi-rotor from a crash or other harmful consequence caused by

 low battery voltage, we have designed two levels of low voltage protection. You can

 choose to not to use them, but all two level protections have LED warning as default.

 First level will blink yellow light continuously; second level will blink red light

 continuously. Compare the Go Home and Landing of low voltage protection and the Go

 Home and Landing in Enhanced Failed-safe, the generations of Home Location are the

 same; the Go Home routes are the same; the difference is that there is no hovering before

 landing in low voltage protection.

Upgrade To Ground Station Control System

WooKong-M can be upgraded to ground station which is a more powerful unmanned

 platform to satisfy the high requirement of customers.

Now you just need to buy a DJI professional datalink and upgrade to the latest

 WooKong-M 5.26 firmware, then free Ground Station function is available without S/N

 and free 50 waypoints supported. Besides the 3D map, it also contains such ground

 control functions as joystick/keyboard control, one key takeoff and click & go.

Introduction 

DJI iOSD is specially designed for DJI autopilot system during the FPV flight or other aero-modeling activates. DJI iOSD 

can transmit video and iOSD information in real time, which will help you to obtain the aircraft status information during a 

FPV flight. It can display power voltage, flight velocity, height, distance from the home point, horizontal attitude, GPS 

satellite number, etc. iOSD and video information are superposed on the receiver, making iOSD data clearly visible and 

bringing you a more involved flight experience. 

DJI iOSD should be used in conjunction with a DJI autopilot system. It supports two video input sources under PAL or 

NTSC mode, which can be selected remotely by an R/C transmitter switch. The R/C TX switch can also change the 

wireless video transmitter channel remotely when user uses the wireless video transmitter specified by DJI. The iOSD 

supports online upgrades. The iOSD has built-in BEC, which is on one hand for the power supply of the camera, on the 

other hand for the power supply of the autopilot system’s main controller to improve the power supply reliability of the

Connection to PC 

To connect board to your PC, you need a miniUSB cable. First time a USB cable is plugged, you need 

to install the appropriate software driver. If your PC does not install the driver automatically, install one 

manually from this link: http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx. 

After you install the driver and connecting the board, a new virtual COM port will be created. You need 

to choose this COM port in the SimleBGC software (GUI) to initiate the connection. 

It is safe to connect USB and main power (battery) simultaneously. But be very careful to not reverse 

the polarity of the main battery, because in this case it will burn out controller and may damage your 

PC!

There is also a possibility to use Bluetooh–To-Serial adapter (HC-05, HC-06, Sparkfun BlueSMiRF, and 

comparable) to connect to the GUI and tune the board remotely. There is a special connector on the 

board that matches the same one on the BT module. It is marked as UART and contains pins: 5V, 

GND, RX, TX. You can solder BT module over it or use extender Male-Male 4pin cable.

IMPORTANT NOTE: Bluetooth module must be configured at 115200 baud rate and Even

parity (generally its not set by default!). Refer your module's user manual to find out how to 

configure bluetooth. With these settings, you will be able connect to the GUI and even to 

upgrade firmware remotely.

Running application

Follow these steps to connect your main controller board to the GUI software:

 Connect the mini-USB cable

 Start the GUI, select correct COM-port from the list, and click "Connect". 

After the connection is established, all board settings and profiles will be loaded into the 

GUI. You can re-load the current board parameters anytime by clicking the "READ" button.

 After adjusting parameters in the GUI you should write them to the controller board by 

clicking the "WRITE" button. Only the current profile parameters will be saved to the board. 

To return to the default settings push the "RESET TO DEFAULTS" button.

 To choose a different profile (with different settings) select it from the list of profiles (located 

in the upper right corner of the GUI window). You can store different settings as three 

different profiles onto the controller board. You can switch profiles saved on the board by 

choosing the profile in the GUI or by pressing the MENU button on the controller board.

Remember that some settings are common for all profiles and can not be saved on a per-profile basis. 

Parameters such as sensor orientation, hardware configuration, RC inputs, and motors outs are the 

same across all profiles.

The GUI starts in the English version of the user interface. To change the interface language, choose 

one in the 'language' menu and restart the program.

GUI Blocks

The GUI contains different functional blocks:

1. Configuration block in the central part of the window, organized by ‘tab’: 

 Basic – Basic gimbal stabilization settings. Adjusting these settings is usually adequate to 

achieve good camera stabilization.

 Advanced — More precise tuning options. 

 RC Settings – settings to control the gimbal roll/pitch/yaw orientation with RC inputs.

 Service – Specify the behavior of the MENU button (located on the controller board or 

mounted externally) and tune the battery monitoring service.

 Follow Mode – settings related to special mode of the camera control.

 Real-time Data — real-time sensor data monitoring. This screen is extremely helpful in 

tuning your gimbal performance. Firmware Update — Firmware and GUI software versions 

and update options.

 Firmware Upgrade – lets you to check the fresh version of firmware and upgrade if 

necessary.

2. Connection — COM-port selection and connection status.

3. Profile — Profile selection, loading, re-naming, and saving. 

4. Control Panel — graphic visualization of gimbal orientation angles in three axes. 

 Black arrows are displaying the angles, blue arrows are a 10x time magnification to provide 

higher precision. Red marks show target angles that gimbal should keep. 

 Thin blue lines shows the maximum (peak) deflection from the central, neutral point.

© 2013-2014 Basecamelectronics® 3

60
 Blue digits show peak deflection amplitude. Using these numbers, stabilization quality can

be estimated.

 Vertical red bars to the right of the scales show actual power level, from 0 to 100%.

5. READ, WRITE, RESET TO DEFAULTS buttons are used to transfer setting from/to board.

6. MOTORS ON/OFF button is used to toggle motors state.

7. At the bottom of the screen, tips, status or error messages (in red color) are displayed . Overall 

cycle time and I2C error count is also displayed.

8. Battery voltage indicator with warning sector.

Basic Settings

Note: Before tuning your controller, install the camera into the gimbal firmly and ensure your gimbal’s 

center of gravity is leveled as much as possible.

 P,I,D – PID regulation parameters for all axes. .

◦ P – describes the power of disturbance response. Higher values means a stronger 

response reaction to external disturbance. Raise this value until the stabilization quality of 

fast disturbances will be adequate. If the “P” value is too high, oscillations of the axis will 

start to be present. These oscillations will get worse if there are vibrations that reach the 

IMU sensor board. If oscillations occur, raise the “D” parameter by 1 or 2 units, and then try 

to raise the “P" value again.

◦ D – The “D” value reduces the reaction speed. This value helps to remove low-frequency 

oscillations. A “D” value that is too high can cause high-frequency oscillations, particularly, 

when the IMU sensor is exposed to vibrations.

◦ I – The “I” value changes the speed at which the gimbal moves to incoming RC commands 

and to move the gimbal back to neutral. Low values result in a slow and smooth reaction to 

RC commands and to getting back to neutral. Increase this value to speed up the 

movement

 Limit Accelerations - this option lets to limit angular accelerations in case of hard RC or Serial 

control (useful to prevents jerks or skipped steps, smoother camera control, less impact on the 

multirotor's frame). The less is value, the smoother is camera rotation under control.

 POWER – maximum voltage supplied to the motors (0 - 255, where 255 means full battery 

voltage). Choose this parameter according to your motor characteristics. Basic tuning:

◦ Motors should not get too hot! Motor temperatures of over 80С will cause permanent 

damage to motor magnets.

◦ A Power value that is too low will not provide enough force for the motor to move the gimbal

and stabilize the camera adequately. A low power value will be most noticeable in windy 

conditions, when the gimbal is not well balanced, or if the gimbal suffers from mechanical 

friction. Slowly lower the Power parameter to find its optimal value. Find the lowest value 

that still provides good stabilization and adequate holding torque.

◦ Raising the power equals raising the “P” value of PID settings. If you raise the POWER 

value, you should re-tune your PID values as well.

 “+” - Additional power that will be add to the main power in case of big error (caused by 

missed steps). It helps to return camera to the normal position. If main power + additional power

is greater than 255, the result is limited to 255.

 INVERT – reverse motor rotation direction. It's extremely important to choose the correct motor 

rotation direction to not damage your gimbal. To determine the correct direction, set the P, I, and

D values to 0 and the POWER values to 80 (or higher if your motors don’t produce enough 

force to hold/move the camera). Level the camera tray horizontally and click the AUTO button in

the "Motor configuration" settings. The gimbal will make small movement to determine correct

motor rotation direction. Wait for the calibration procedure to complete. Then, re-set your PID 

values and tune your Power values.

 NUM.POLES – Number of motor poles. This value needs to be equal to the number of magnets

in your motor’s bell. During the “auto” calibration process described above, this value is 

automatically detected. However, this value is sometimes not correctly determined during the 

“auto” calibration process and will need to be verified and possibly corrected manually. Most 

brushless gimbal motors are built with 14 poles (or magnets) and utilize a DLRK winding 

scheme. Count your motor magnets and enter this value if the value is not correct in the GUI.

 External FC Gain – Gain value for matching the gimbal data from your flight controller 

(optional). For better stabilization and utilization of some additional features, the knowledge 

about the frame inclination angles is required. SimpleBGC IMU doesn't provide such 

information. Most of FC have servo outs for connecting gimbals. This outs should be connected 

to SimpleBGC controller through EXT_ROLL and EXT_PITCH inputs.

◦ Activate gimbal outs in FC and set range limits for angles you generally fly (for example ,+-

30 degrees of frame inclination should equals full servo range about 1000-2000).

◦ Deactivate all filters and smoothing of FC gimbal settings (if present).

◦ In the RC-settings tab, make sure that inputs EXT_ROLL, EXT_PITCH doesn't used to 

control gimbal. (i.e. are not chosen as source for any other RC control task).

◦ In REALTIME DATA tab, check availability of EXT_FC_ROLL, EXT_FC_PITCH signals, and

make sure they are split to axes correctly. (Frame roll angle tilting should cause 

EXT_FC_ROLL change in approximately 900..2100 range. The same is for pitch.)

◦ Connect power supply, and setup stabilization as described above (tune POWER, INVERT, 

PID)

◦ Push AUTO button in FLIGHT CONTROL GAIN group, and smoothly incline copter frame 

to different directions by all axes for 10-30 seconds.

◦ Push AUTO button again to complete calibration. (Calibration will stop automatically after 

some time too). New gains will be written into EEPROM and shown in the GUI.

NOTE : You may skip this step and leave zero values at initial setup.

 Sensor — Specify your IMU sensor board’s orientation and position on the gimbal . For a 

standard IMU sensor installation, look at the gimbal from behind just like the camera will view 

out from the gimbal. Viewing the gimbal in this way, the UP and Right direction will match the Z 

and X axis. You can place the IMU sensor in any direction, keeping its sides always parallel to 

the motor axis (be very accurate here, it is a very important to precisely align the sensor and 

mount it firmly). Configure your IMU orientation in the GUI. The correct configuration should 

result in the following:

▪ Camera pitches forward – the PITCH arrow spins clockwise in the GUI.

▪ Camera rolls right - ROLL arrow spins clockwise in the GUI.

▪ Camera yaws clockwise - YAW arrow spins clockwise.

◦ Skip Gyro calibration at startup - With this option, the board starts working immediately 

after powering it on, using the saved calibration data from last gyroscope calibration call. 

However, stored calibration data may become inaccurate over time or during temperature 

changes. We recommend you to re-calibrate your gyro from time to time to ensure the best 

performance.

Second IMU sensor

There is an option to install the second IMU sensor on the gimbal's frame. The advantage is more 

precise stabilization (you may use lower PID's to get the same quality) and knowing of frame tilting, that

greatly helps for 3-axis system to extend the range of working angles.

Second IMU should be connected to the same I2C bus as main (in parallel). Sensors should have 

different I2C-address (Main IMU – 0x68, Frame IMU – 0x69). On the Basecam IMU, address 0x69 may 

be set by cutting the ADDR bridge, located on the back side of the sensor:

Mounting the Frame IMU

There are two options where to place the second IMU: below YAW motor and above it. In case of 2-

axis stabilization, there is only one option – above ROLL motor. 

If the sensor is placed above YAW motor, it helps to stabilize ROLL, PITCH and YAW motors. But the 

system becomes less stable during long work (because the frame heading, estimated from the second 

IMU, may drift with time and auto-correction may not work in all cases). 

If the sensor is placed below YAW motor, it does not help YAW axis stabilization, but works more 

reliable.

Like the main (camera) IMU, the frame IMU may be mounted in any orientation, keeping its axis parallel

with motor's axis.

Configuring the frame IMU

To configure the frame IMU, first of all set its location in the “Advanced” tab, “Sensor” area. Write 

settings to the board and go to the “Basic” tab. Press the button “Frame IMU”:

If the second IMU is connected properly, this button becomes active. It means that all IMU settings now

affect on the frame IMU. Change sensor orientation (axis TOP, RIGHT) and write setting to the board, if

necessary (board will be restarted). After restart, calibrate the accelerometer and gyroscope like you did

it for the main IMU. For the accelerometer, you can do simple calibration or extended 6-point 

calibration.

You may notice that right panels with arrows are displaying now angles not for the main, but for the 

frame IMU. Also, in the “Realtime Data” tab, accelerometer's and gyroscope's data go for the frame 

IMU. It helps to properly configure an orientation of the sensor and check its calibration.

RC Settings tab

 RC Input Mapping – here you can assign hardware RC inputs to virtual control channels. 

There are 4 hardware inputs provided on the board for RC Radio control connections, which 

you can assign to control any of three channels, one for each axes, and one command channel.

If control for an axis is not needed, leave the option at "no input".

 RC_ROLL pin mode – allows to configure several formats of incoming signal for RC_ROLL pin:

◦ Normal – incoming signal is in the PWM format, that most RC-receivers generally outputs 

◦ Sum-PPM - some receivers may have this signal output. It is a PWM format modification, in 

which every channel transmits sequentially through one cable. In this case you do not need 

to connect other channels (read your receiver's user manual to check if it has SumPPM 

out). 

◦ Futaba s-bus – receivers made by Futaba may transmit data in special digital format, up to 

16 channels by one wire. Connect it to RC_ROLL pin.

◦ Spektrum – another digital multi-channel protocol, that is used to communicate Spektrum's 

satellite modules with the main module, and in its clones. Because there are many 

modifications of this protocol, it may not work as expected in the first versions of 

SimpleBGC firmware (but we will work on correct implementation in next versions). There is 

a dedicated socket on the board (marked Spektrum) that matches standard connector. You

should bind satellite module with the transmitter manually.

 For each control targets you can choose appropriate hardware input from the drop-down list.

◦ RC_ROLL, RC_PITCH, RC_YAW, FC_ROLL, FC_PITCH – hardware inputs on board that 

accept signal in the PWM (Pulse Width Modulation) format (excepting RC_ROLL, see 

above). Most RC receivers output this signal type.

◦ ADC1, ADC2, ADC3 — dedicated analog inputs, marked on the board as A1, A2, A3 and 

accepts analog signal in range from 0 to +3.3 volts. For example, joystick variable resistor 

provides such signal. Connect A1..A3 to the center contact of variable resistor, +3.3V and 

GND to side contacts. See Connection Diagram for more info.

◦ VIRT_CH_XX – In case of RC_ROLL pin mode is set to multi-channel signal format, you 

can chose one of the virtual channels.

 Control targets:

© 2013-2014 Basecamelectronics® 7

64
◦ ROLL, PITCH, YAW - controls the position of the camera

◦ CMD allows to execute some actions. You can configure 2- or 3-position switch on your RC 

for specified channel, and assign it to CMD channel. Its range is splitted into 3 sections : 

LOW ,MID ,HIGH. When changing the position of your RC-switch, signal jumps from one 

section to another, and assigned command is executed. The full list of available commands 

is described in the section “MENU BUTTON” of this manual.

◦ FC_ROLL, FC_PITCH – is used to mark any of PWM inputs to be a signal from the external

flight controller. See “External FC gain” section for details.

 RC Mix - you can mix 2 inputs together before applying to any of ROLL, PITCH or YAW axis. It 

lets to control the camera from the 2 sources (joystick and RC for example). You can adjust the 

proportion of the mix from 0 to 100%.

 ANGLE MODE — RC stick will control the camera angle directly. The full RC range will cause a

camera to go from min to max angles, as specified above. If RC stick doesn't move, camera 

stands still. The speed of rotation depends on the “SPEED” setting and the acceleration limiter 

setting.

 SPEED MODE — RC stick will control the rotation speed. If stick is centered - camera stands 

still, if stick is deflected, camera starts to rotate, but does not exceed min-max range. Speed is 

slightly decreased near min-max borders. Speed of rotation is proportional to stick angle and 

the SPEED setting. RC control inversion is allowed in both of control modes.

 MIN.ANGLE, MAX.ANGLE – range of the angles controlled from RC or in Follow mode. To 

inverse the control, set higher value first, and lower value second. For example, if you want to 

configure a camera to go from leveled position to down position, set 0-90 (or 90-0 to inverse).

 LPF – Control signal filtering. The higher is value, the smoother is reaction to the stick 

commands. This filter cuts fast stick movements, but adds some delay.

Follow Mode 

There is a special control mode, when the camera “follows” for a tilting of the outer frame, but 

eliminates small frame jerking. Several modes of operation are possible:

• Disabled – camera is locked to ground and may be rotated only from RC.

◦ Estimate frame angles from motors - it use magnetic field for rough estimation of frame 

tilting. Helps to increase the range of the frame angles where the gimbal's operation is 

stable. To proper operation in this mode, it is strictly required to calibrate Offset setting (see 

below). Like with the Follow mode, its not recommended to use this option in flight, its 

dedicated for hand-held systems only. 

NOTE that this option is ignored if you connect second IMU mounted on the frame, because

the data from the second IMU is more precise than from motors.)

• Follow Flight Controller – camera is controlled from RC together with the mixed signal from 

an external flight controller (FC). Almost every FC has servo outputs to drive a gimbal. It feeds 

the information about the frame angles to this outputs, in the PWM format that all servos 

understand. SimpleBGC can get this information and use it to control a camera. It is necessary

to connect and calibrate external flight controller (see EXT.FC GAIN settings). After calibration 

you can setup the percentage values for ROLL and PITCH axis, so the camera will follow frame 

inclinations.

• Follow PITCH, ROLL – this mode is dedicated to

hand-held systems. FC connection is not required.

In this mode, the position of the outer frame by

PITCH and ROLL is estimated from the motor's

magnetic field. This means that if motor skips steps,

position will be estimated incorrectly and operator

should correct camera by hands, returning it to

proper position. You should use this mode carefully

for FPV flying, because if the camera misses its

initial direction, there is no chance to return it back

automatically.

◦ Follow ROLL start, deg. - Set the angle (in degrees) of the camera PITCH-ing up or down,

where the ROLL axis enters follow mode. Below this angle, ROLL is in lock mode.

◦ Follow ROLL mix, deg. - Set the range (in degrees) of the camera PITCH-ing, where the 

ROLL axis is gradually switched from the 'lock' mode to 'follow' mode (see picture)

Hint: to completely disable follow for ROLL, set these values to (90, 0). To permanently 

enable follow for ROLL (regardless of the camera PITCH-ing), set values to (0, 0).

• Follow YAW – the same as above, except it can be enabled only for YAW axis. For example, 

you can lock camera by ROLL and PITCH axis by selecting “Disabled” option, but still control 

camera by YAW by enabling “Follow YAW” option.

There are additional settings to tune follow mode:

• Dead band, degrees: you can set the range where the rotation of an outer frame does not 

affect the camera. It helps to skip small jerks when you operate gimbal by hands.

• Expo curve: you can specify the strength of the control when outer frame declines from neutral 

position. For example: when the expo curve is enabled (i.e. is not flat), small or medium 

declination of an outer frame will cause very fine control even if I-term is configured high. But 

the strength of control exponentially grows when angles of declination becomes close to 60 

degrees. It gives a big freedom in camera operation: from fine and smooth control to very fast 

movements.

• OFFSET: it is a very important to properly configure the initial position of the motor's magnetic 

poles, because all further calculations use this information. For YAW axis it allows to fine adjust 

a camera heading relative to a frame heading. For PITCH and ROLL axis there is an option to 

calibrate offset automatically. To do this, power on system, hold frame leveled, and press AUTO

button. Don't forget to write setting when finished.

If the camera after power on is not leveled, you need to adjust the offset setting.

• SPEED - adjust the speed of the camera rotation in the follow mode. Don't set big values that 

motors can not handle (if motor does not produce enough torque, it will skip steps and 

synchronization will be broken). In this case, acceleration limiter may help to have big speed 

but do not miss steps.

Operation in the Follow Mode

At system startup in the follow mode, keep the frame horizontally and manually adjust the camera to 

the horizontal position, and adjust it's heading. Camera easily "jumps" between the magnetic poles. 

Rotate the camera by hands to desired horizontal position, it will stick to the nearest magnetic pole.

Gently rotate and tilt the frame. Turns within ± 45o will control the speed of the camera from 0 to 100%.

Camera rotates in accordance with the SPEED settings until it's angles are not equal the frame's 

angles, or until given restrictions will be achieved. 

If the camera moves unpredictably, perhaps its the wrong direction of rotation of the motors and you 

need to change the Reverse flag in the 'Basic' tab .

To achieve the smooth motion, increase the LPF parameter (in the 'RC' tab), increase Expo curve, 

and decrease the SPEED and the Acceleration limits. For more dynamic control, change these 

settings in the opposite direction.

In case of failure of stabilization due to external disturbances, the camera can completely lose 

synchronization with the frame . In this case, it is necessary to return it to the proper position by hands. 

IT IS VERY IMPORTANT to keep the frame horizontally, because at this point the frame's zero angles 

are calibrated. 

You can switch between modes on-the-fly by activating different profiles. Camera will keep their position

between modes.

Advanced tab

 AHRS - options influencing on camera angle determination accuracy.

◦ Gyro trust – The higher is value, the more trust to the gyro data compared with the 

accelerometer data when estimating angles. It can reduce errors caused by accelerations 

during moving, but also decreases gyro drift compensation, resulting in horizon drift over 

time. For smooth flying, it is recommended to set low values (40-80), which will give more 

stable horizon for longer time. For aggressive flying, it's better to set higher values (100-

150).

◦ Accelerations compensation – enable it to use a physical model of multirotor to 

compensate accelerations during flight. This option works only when external FC is 

connected and calibrated.

 Serial port speed — changes baud rate used for serial communication. Decrease it when 

using over-the-air serial adapters that can't work on maximum speed. The GUI can auto-detect 

the baud rate configured in the board.

 PWM Frequency — sets the PWM frequency used to drive motors by power stage. Two modes

are available : Low Frequency (in audible range) and High Frequency (outside audible range). 

In the high frequency mode it is necessary to increase the POWER setting a bit.

 Motor outputs — you can assign hardware motor outs for any of stabilization axes. For 

example, you can use second controller for YAW stabilization and set it up this way: 

ROLL=disabled, PITCH=disabled, YAW=ROLL_OUT, and connect a YAW motor to hardware 

ROLL_OUT.

 RC Sub-Trim – allows to correct transmitter inaccuracy.

◦ ROLL, PITCH, YAW trim – central point trimming. Central point here is PWM 1500. It's 

better to trim it in transmitter. But in case of it is not possible (when using joystick, for 

example), you can use AUTO function in the GUI. Just place stick in center, and press 

AUTO button. Actual data becomes new center point. Press WRITE button to apply settings.

◦ Dead band — adjusts a dead band around neutral point. There's no control while RC signal

is inside this range. This feature works only in SPEED mode, and helps to achieve better 

control by eliminating jitters of stick around neutral point.

◦ Expo curve – adjusts the curvature of an exponential function, that allows to get precise 

control from RC in the range of the small values, but rough and strong control near 

endpoints. Works only in SPEED mode.

 Sensor

◦ Gyro LPF – adjusts filtering gyro data. It's not recommended to set values different than 0,

67
because it will make adjusting PID controller harder. You can experiment with this.

◦ Gyro high sensitivity - Increases gyro sensitivity twice. Use this option for big-sized DSLR 

cameras, in case if your PID settings are close to upper limits, but stabilization still not good.

Increasing gyro sensitivity equals to multiplying P and D values by 2.

◦ I2C Pullups Enable - turns ON built in I2C pull-up resistors for SDA and SCL lines.

Use function on only if sensor doesn't work properly.

◦ Frame IMU – set the location of the frame IMU. See Second IMU sensor section of this 

manual.

Service tab

Menu Button

If you've connected menu button to BTN connector on the controller, you can assign different actions to 

it.

Available actions:

 Use profile 1..5 — loads selected profile

 Calibrate ACC – the accelerometer calibration, works the same way as button in the GUI.

 Calibrate Gyro – gyroscope calibration.

 Swap RC PITCH – ROLL — temporary swap RC inputs from PITCH to ROLL. In the most 

cases only one PITCH channel is enough to control a camera in 2-axis systems. Before a flight 

you can assign control from pitch channel to roll, and make a camera precisely leveled. 

Activating this function again swaps channels back, and saves roll position in the static memory.

 Swap RC YAW – ROLL — like the previous point.

 Set tilt angles by hand – motors will be turned off, after that you can take the camera in hands

and fix it in the new position for a few seconds. Controller will save and hold the new position. 

This function may be useful to correct camera position before flight if there is no RC control 

connected.

 Motors toggle, Motors ON, Motors OFF - commands to change the state of the motors.

 Reset controller

Battery Monitoring

On some latest board versions there is a voltage sensor installed to monitor the main battery voltage. It 

is used to apply voltage drop compensation (PID becomes stable during whole battery life-cycle), and 

to make low-voltage alarms and do the motor cut-off when the battery becomes discharged.

• Calibrate - adjusts the rate of internal multiplier to make measured voltage more precise. You 

need a multimeter to measure the real voltage, than enter this value in the calibration dialog.

• Low voltage - alarm - set the threshold to make alarm when the voltage drops below it.

• Low voltage - stop motors - set the threshold to stop motors when the voltage drops below it.

• Compensate voltage drop - set this option to automatically increase the POWER parameter 

(which controls the output power goes to the motors), when the battery loose voltage due to 

discharge process.

• Set defaults for - select the battery type to fill the fields above with the default settings for 

selected type.

NOTE: you can add the voltage sensor to old boards in DIY way, by soldering a voltage divider 

33k/10k: 33k goes to the battery “+”, 10k goes to the GND, and common point goes to the pin 19 of 

the 328p MCU (if this pin is grounded, de-solder it first).

Buzzer

On some boards there is an output to the buzzer. It is used to buzz on some events. Events are 

© 2013-2014 Basecamelectronics® 11

68
configured (turned ON or OFF) in the GUI. You can connect an active buzzer only (which has an 

internal sound generator), working from 5..12V, currents below 40mA (check this Digikey product 

search for example)

NOTE: you can connect the buzzer to old boards in DIY way, by soldering its “+” wire to the pin 32 

of the 328p MCU, and “-” wire to the GND.

Realtime Data tab

In this tab you can see raw sensor data stream, and logical RC input levels.

 ACC_X,Y,Z – accelerometer data.

 GYRO_X,Y,Z – gyroscope data. Helps to determine quality of P and D settings. Disturb gimbal 

by hand and see trace. If it looks like sine wave, D setting is too low and gimbal tends to lowfrequency oscillations. If some noise is always present even without any disturbance, D setting 

is too high and gimbal tends to high-frequency self-excitation.

 ERR_ROLL,PITCH,YAW – stabilization error graph. Same as peak indicators on the control 

panel and shows maximum deflection angle.

Each graph can be turned on or off, scale can be adjusted for Y axis. You can pause the data 

transmission at any time.

Setup step-by-step sequence

1. Adjusting the mechanics

Mount the camera on the tray and balance the gimbal in all three axes. Stabilization quality strongly 

depends on balance quality. To check your balance, pick your turned off gimbal in hands. Make fast 

motions along all axes, try to catch resonance point and swing the gimbal. If it is hard to do - gimbal is 

balanced correctly.

NOTE : Good balance and low friction can scale down power consumption and keep good 

quality of stabilization.

If you rewound motors by yourself, it's recommended to check winding. Remove motors from gimbal, 

connect them to controller and set parameters P=0, I=0.1, D=0 for each axis and set enough POWER. 

Connect main power supply. Motors should spin smoothly, while rolling the sensor. Little jitter is normal 

due to magnetic force between rotor and stator (“cogging” effect).

Pay great attention to sensor installation. Its axes must be parallel with motor axes. Pay attention to 

mechanical links. They must be a VERY RIGID and backlash-free. Sensor provides feedback data for 

stabilization, and even any little freedom or flexibility will cause delays and low-frequency resonances. 

This can complicate setting of PID, and cause unstable work in real conditions (frame vibrations, wind, 

etc)

2. Calibrating the sensor

Gyro is calibrated every time you turn the controller on, and it takes about 4 seconds. Try to immobilize 

sensor (camera) as hard as you can in first seconds after powering on, while signal LED is blinking. 

After powering on you have 3 seconds to freeze gimbal before calibration starts.

If you activated option “Skip gyro calibration at startup”, gyro is not calibrated every time and controller 

start working immediately after powering up. Be careful and recalibrate gyro manually, if you will notice 

something wrong with IMU angles.

Calibrating Accelerometer

You must perform ACC calibration only once, but it's recommended to recalibrate it from time to time or 

when the temperature significantly changes.

© 2013-2014 Basecamelectronics® 12

69
 Simple calibration mode: set the sensor horizontally, and press CALIB.ACC in the GUI (or 

menu button, if it's assigned). LED will blink for 3 seconds. Try not to move sensor during 

calibration. At this step no matter how camera is leveled. You are calibrating the sensor, not the 

camera!

 Advanced mode (recommended): perform calibration in simple mode as above. Then turn 

sensor in order that each side of sensor looks up (6 positions at all, including base one). Fix the 

sensor in each position, press CALIB.ACC button in the GUI, and wait about 3-4 seconds, while

LED if flashing. The order does not matter, but the base position always goes first (because the 

simple calibration cancels a result of advanced calibration). You have not to press WRITE 

button, calibration data is written automatically after each step.

NOTE: Precise accelerometer calibration is a very important for horizon holding during 

dynamic flying or YAW rotation.

4. Tuning basic settings

 Connect the main power supply.

 Set POWER according to the motor configuration (see recommendations above)

 Auto-detect number of poles and motors direction. Do not proceed to next step until proper 

direction will be detected!

 Adjust PID controller. To check stabilization quality, use peak indicator in the control panel 

(shown by the blue traces and blue numbers). Incline the frame by small angles and try to 

minimize peak values by increasing P, I and D to its maximum. You may use gyro data from 

Realtime Data tab to estimate stabilization quality, too.

Better to tune PID with the “Follow Mode” turned OFF for all axes.

Suggested algorythm for PID tuning: 

1. Set I=0.01, P=10, D=10 for all axes. Gimbal should be stable at this moment. If not, 

decrease P and D a bit. Than start to tune each axis sequentially:

2. Gradually increase P until motor starts oscillate (you may knock camera and see on the 

gyro graph, how fast oscillation decays). Increase D a little – it should damp oscillations, 

and decay time decreases. The lower is decay time, the better.

3. Repeat step 2 until D reaches its maximum, when high-frequency vibration appears (you 

may feel it by hands and see noisy line on the gyro graph). Current P and D values are 

maximum for your setup, decrease them a little and go to step 4

4. Increase I until low-frequency oscillation starts. Decrease I a little to keep gimbal stable.

Now you found a maximum for all PID values for selected axis. Repeat from step 1 for 

other axes.

5. When all axes are tuned in static, try to move gimbal's frame, emulating a real work. You 

may notice that cross-influence of axes may make gimbal not stable. In this case, decrease 

a little PID values from its maximum for axes that looses

The result of good tuning – stabilization error is less than 1 degree when you slightly rock a gimbal's 

frame.

5. Connecting and configuring RC

• Connect one of the free receiver's channels to RC_PITCH input, preserving right polarity

In the RC Settings tab:

• Set SORCE=PWM

• Assign RC_PITCH input to PITCH axis 

• Leave all other axes and CMD as “no input”

• For PITCH axis, set MIN.ANGLE=-90, MAX.ANGLE=90, ANGLE MODE=checked, LPF=5, 

SPEED=10 (not used in angle mode)

• Connect the battery to the main controller and receiver, and check that RC_PITCH input 

receives data in the “Realtime Data” tab (slider should be blue filled and reflects to stick 

movement)

Now you can control the camera from your RC transmitter, from -90 to 90 degrees. If you are not 

satisfied with the speed of movement, adjust the I-term setting for PITCH in the “Basic” tab.

Try the SPEED mode and feel difference with the ANGLE mode.

Connect and tune remaining axes the same way, as required.

6. Testing gimbal in real conditions

Connect controller to the GUI and turn ON multirotor motors, holding it above your head. Check the 

vibrations on the camera by using Realtime Data tab / ACC raw data. Try to decrease the level of 

vibrations using soft dampers.

NOTE: Brushless motors versus traditional servos provide faster reaction, but less torque. 

That's why it's hard for them to fight against wind and air flows from props. If you are developing

multirotor frame by yourself, try to avoid this influences (for example, lengthen arms a bit, or tilt 

motors away from center or place camera above props in case of H-frame). Also bear in mind, 

when copter moves with high speed, an air flow is deflected and can affect the gimbal.

Status LED

There are 2 LEDs on board. Red led lights when power is connected. Green/blue LED signals show actual 

state of the system:

 LED is off — pause before calibration, to take hands off or to level gimbal.

 LED blinks slowly – Calibration is in action. Freeze gimbal during this process.

 LED blinks fast — system error, stabilization cannot be performed. To check error description, 

connect to GUI.

 LED is on — normal operation mode.

 LED is on, but blinks irregularly – I2C errors appears. 

Also, additional LEDs may present to signal serial communication on RX and TX line.

deflects by ROLL, and then slowly 

gets to horizon.

-Bad accelerometer calibration

-Sensor is not in parallel with motor 

axes

-Make advanced ACC calibration by 6

positions

-Align sensor with motor axes

During fast motion with acceleration, 

camera deflects, and then slowly gets 

to horizon

-This is normal effect of accelerations -Try to increase Gyro Trust in 

Advanced tab

YAW arrow slowly spins in the GUI -Slow drift is normal (less than 1 

degree/minute). It’s because of gyro 

drifts over time .

-Note to sensor Immobility during gyro

calibration

-Re-calibrate gyro

Camera slowly drifts by any or all axes

just after power on

- Bad gyro calibration -Re-calibrate gyro

Clicks and 

crunch are heard during work. LED is 

synchronously blinking.

-I2C errors present. Errors are 

possible if sensor wires are too long, 

or motors outs affect sensor by 

capacitive linkage.

-Shorter sensor wires;

-Lower pullup resistors value on the 

sensor board;

-Install spike LC-filter on motor outs 

(make 2-3 turns of motor cable 

through ferrite coil);

- Install spike LC-filter on sensor wires

(the same as motor filter);

- Replace sensor with version with 

LLC;

High-frequency oscillations. -Feedback self-excitation as a result 

of high D parameter

-Check the graphs to understand on 

what axis is the problem, and lower D 

value.

Low-frequency oscillations. -Feedback self-excitation as a result 

of high D parameter or high P

Lower P, increase D

GUI cannot connect to the board. -Wrong COM-port selected

-GUI and firmware versions doesn’t 

match.

-Try different COM-ports

-Upload the latest firmware, and 

download matching GUI version.
