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.

SkyFly Cinema , LLC

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 SkyFly Cinema, LLC (“ SkyFly Cinema ”) an operator of Sma ll Unmanned Aircraft Systems (“ UA s ”) for the commercial purposes of aerial photography, videography, and cinematography . Specifically, petitioner seeks an exemption from the Federal Aviation Regulations (“FARs”) listed in Appendi x A to allow commercial operation of its UA s, so long a s 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. This request is substantially similar to other data collection petitions previously approved, and should be con sidered under the expedited summary grant procedure.

Approval of the exemption for petitioner will allow operation of the Cinestar 8 HL and Copterworks Af25b for the proposed uses in Class G airspace nationwide , or as otherwise prescribed by an Air Traffic Organization (ATO) issued COA

. The Cinestar 8 family has been previously approved for the proposed uses in the exemption grants identified in Section VII of the petition. The Cinestar 8 HL is a small battery

- powered aircraft weighing 18.7 lbs. The Copterworks Af25b is larger, h as a dry weight of 35 lbs., a maximum takeoff weight of 71 lbs. and is powered by a fuel mixture of gasoline and oil. Operation of these UAs under the strict conditions propos ed below will provide an equivalent level of safety, as Congress intended, while still allo wing commercial operations. Operations using these UAs are far safer than conventional operations conducted with helicopters and fixed

- wing aircraft that weigh thousands of pounds

, carr y la rge amounts of highly flammable fuel, and operat e in close proximity to the ground, trees, infrastructure , and people.

Congress directed the FAA to consider seven factors in deciding whether to approv e Section 333 exemption petitions

- size, weight, speed, operational capability, proximity to airports, proximity to populated areas, and operation within visual line of sight . In this case, each factor

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:

Petitioner 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. 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. 91.109; 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. 91. 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 (2) ; and 14 C.F.R. 91.417 (a) and (b) to operate commercially small unmanned aircraft system s ( UAs ) ( 71 lbs. or less ).

Approval of the exemption requested by petitioner will allow commercial operation of the Cinestar 8 HL and Copterworks Af25b for the purpose s of aerial photography, videography, and cinematography in Class G airspace nationwide, unless otherwise prescribed by an ATO

- issued COA. The requested exemption should be grante d because operation of UA s weighing no greater than 71 lbs. (32.2 kg)

, inclusive of battery and/or fuel

, 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 large amounts of highly flammable fuel, and operating in close proximity to the ground and people. The seven factors Congress directed the FAA to consider when approving Section 333 exemption petitions

- size, weight, spe ed, 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. The subs tantial increase of safety and decrease of risk to human life, coupled with the low risk use of UA s to conduct these operations, weigh heavily in favor of granting the exemption.

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 t han 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 f or 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.

Approval of the commercial operations outlined in this petition presents no national security issue. The PIC will possess, at minimum, a sport pilot’s certificate . Therefore, he or she will have been subject to security screenings by the Department of Homeland Security.

V. Proposed Conditions of the Exemption

1. The UA s , including battery and technical payload

, will weigh no more than approximately 71 lbs. (32.2 kg).

2. UA operations under this exemption will be limited to conducting operations for the purpose of aerial photo graphy, videography, and cinematography in Class G airspace nationwide

, unless otherwise prescribed by an ATO issued COA

.

3. Flights will be operated within line of sight of a PIC and VO

.

4. Flights will be operated at an altitude of no more than 4 00 feet AGL, as indicated by the procedures specified in the operating documents. All altitudes reported to ATC must be in feet AGL.

## 9

5. The UA s will not be flown at an indicated airspeed exceeding 39 knots.

6. Minimum flight crew for each operation will consist of the UA PIC and a VO

.

7. The PIC will possess at a minimum sport pilot license and either a third class medical certificate or a U.S. driver’s license.

8. The petitioner will not permit any PIC to operate the UA unless the PIC meets its qualification criteria and demonstrates the ability to safely operate th e UA s in a manner consistent with how the UA s 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 w ith 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 traini ng, proficiency, and experience

- building flights, all persons not essential for flight operations will be considered nonparticipants, and the PIC will operate the UA s 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 re gard 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 s , in cluding the Ground Control Station, to ensure it is in a condition for safe flight. If the inspection reveals a condition that affects the safe operation of the UA s , the PIC will not operate the UA s until the necessary maintenance has been performed and th e UA s are 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 rec ord keeping requirements, in accordance with the UA manufacturer’s aircraft/component, maintenance, overhaul, replacement, inspection, and life limit requirements set forth in the operating documents. Maintenance, inspection, alterations, and status of rep lacement/overhaul component parts will be noted in the aircraft records, including total time in service, description of work accomplished, and the signature of the authorized person returning the UA to service. The authorized person will make an entry in the aircraft record of the corrective action taken against discrepancies discovered between inspections.

## 10

15. 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.

16. 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 prepare to land with at least 25% battery power remaining.

17. Actual total flight time for each operational flight will result in no less than a 25% battery

reserve

.

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

19. The UA will be programmed so that if it loses communications 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

20. If the UA and its radio control link disconnect during flight, the system’s failsafe protection will be triggered and the multiro tor will return to home and land automatically, rather than flying off uncontrollably or landing at an unknown location.

21. The operating documents required under 14 CFR §§ 91.9 and 91.203 will be maintained and available to the PIC at the Ground Control St ation of the UA any time the UA s are operating. These documents will be made available to the Administrator or any law enforcement official upon request. If a discrepancy exists between the conditions and limitations in the exemption grant and the procedur es 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 documen ts, 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 amendmen t to the grant of exemption.

22. Petitioner will obtain written and/or oral permission from the landowners/authorized agents of the landowners over which flights will be conducted.

23. 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.

24. UA operations will not be conducted during night, as defined in 14 CFR § 1.1. All operations will be conducted under visual meteorol ogical conditions (VMC). Flights will not be conducted under special visual flight rules (SVFR).

25. The petitioner will obtain an Air Traffic Organization (ATO) issued Certificate of Waiver or Authorization (COA) prior to conducting any operations under th e grant of exemption. Petitioner will request a Notice to Airman (NOTAM) not more than 72 hours in advance, but

## 11

not less than 24 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.

26. 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 w ith 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.

27. Th e 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.

28. All operations shall be conducted in Class G airspace or as otherwise prescribed in an A TO issued COA.

29. 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.

30. 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 ove rsight agency requirements.

31. The UA will remain clear and yield the right of way to all manned aviation operations and activities at all times.

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

33. Petitioner will conduct all flight operations at least 5 00 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 nonpartic ipating persons from the UA s 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 fee t of the UA s , the PIC will ensure that fligh t 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 safet y 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).

34. 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 r eport accidents to the National Transportation Safety Board (NTSB) per instructions contained on the NTSB Web site: www.ntsb.gov

.

## 12

35. The petitioner will have a motion picture and television operations manual (MPTOM) available at the Ground Control Station, submitted as Exhibit 2 to this petition request.

36. At least 3 days before aerial filming, petitioner will submit a written Plan of Activities to the local Flight Standards District Office (FSDO) with jurisdiction over the area of proposed filming. The 3-day notification may be waived with the concurrence of the FSDO. The plan of activities will include at least the following:

a. Dates and times for all flights; b. Name and phone number of the operator for the UA aerial filming conducted under this grant of exemption;

c. Name and phone number of the person responsible for the on-scene operation of the UA ; d. Make, model, and serial or N−Number of UA to be used;

e. Name and certificate number of UA PICs involved in the aerial filming; f. A statement that the operator has obtained permission from property owners and/or local officials to conduct the filming production event; the list of those who gave permission must be made available to the inspector upon request;

g. Signature of exemption holder or representative; and h. A description of the flight activity, including maps or diagrams of any area, city, town, county, and/or state over which filming will be conducted and the altitudes essential to accomplish the operation.

37. Flight operations may be conducted closer than 500 feet from participating persons consenting to be involved and necessary for the filming production, as specified in the petitioner ’s MPTOM, Exhibit 2.

VI. Privacy

There is little concern that the proposed flights will cause invasions of privacy. All flights will occur over either (a) public rights of way where there is no expectation of privacy; or (b) over private property with permission of the landowner/authorized agent and consent of participating individuals.

If data collected is made available for public view, all images containing uninvolved persons will be blurred or blacked-out. No attempt will be made to identify any individuals filmed during the flights except in cases where they are trespassing upon or damaging customer property, or interfering with the petitioner’s or its customers’ operations.

VII. Public Interest and Safety

The planned UA use will increase ground safety for aerial photography, videography and cinematography. This type of data collection has previously been done by manned aircraft or by individuals on the ground. Both are more time consuming and are more expensive than using UA s

. Use of manned aircraft poses enhanced risk to the pilot and onboard crew, who would be several hundred feet in the air.

The enhanced safety and reduced environmental impact achieved using UAs and carrying no passengers or crew, rather than a manned aircraft of significantly greater mass, carrying crew in addition to large amounts of flammable fuel, gives the FAA good cause to find that the UA

## 13

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, 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 petitioner’s UA s for aerial photography, videography, and cinematography pursuant to SkyFly Cinema ’s rules of operation.

Please refer to the following Exhibits for petitioner’s internal rules to ensure safety: Exhibit 1: SkyFly Cinema sUAS Flight Operations Manual Section 15: Risk Management Section 16: Onside Safety Assessment Exhibit 2: SkyFly Cinema Movie Production Television Operations Manual Section 15: Risk Management

The FAA has determined that the use of the Cinestar 8 family is in the public interest in the fo llowing Exemption Nos.: 11251 (Cinestar 8, cinematography); 12496 (Cinestar 8 Octo, cinematography); 12697 (Cinestar 8, cinematography); 11284 (Cinestar 8 HL, closed-set motion pictures, television and film); 11854 (Cinestar 8 HL, closed-set motion pictures); 12473 (Cinestar 8 HL, filming and motion pictures); 11488 (Cinestar 8, closed-set motion pictures and commercial videography); 12008 (Cinestar 8, closed-set motion pictures); 12092 (Cinestar 8, film industry); and 12318 (Cinestar 8, closed-set motion pictures).

The Copterworks Af25b is a larger UA, with a frame weight of approximately 35 lbs., a maximum fuel weight of approximately10 lbs., and a maximum takeoff weight of 71 lbs. The FAA has previously approved UAS operations where the UA weighed significantly more than 55 lbs. in Exemption No. 11448 (maximum takeoff weight not to exceed 218 lbs.). However, should the FAA require additional information or time before approving the Copterworks Af25b to operate at its full takeoff weight, petitioner requests that the FAA allow it to operate at weights up to 55lbs.

The Copterworks Af25b is a gasoline-powered UA. The FAA has previously determined that operation of UAs fueled by gasoline is in the public interest in Exemption Nos. 12080, 12090 and 12586.

# 1 Flight-Ctrl V1.0: Schematic, Parts Soldering and Getting Started

1.1 Tasks

This board is the MikroKopter ’s control board . It fulfils the following tasks:

measuring the angular velocity of the three axes • measuring the acceleration data of the three axes • measuring the atmospheric pressure for altitude control • evaluation of a digital compass signal • measuring the battery voltage • evaluation of the R/C signal • processing of sensor data and computing the actual angular position • driving four Brushless ESCs (electronic speed controllers) •



# 1.2 Other Features:

Dimensions 50 * 50mm • Two LEDs (e.g. Okay & Error) • Two transistor outputs for external lights (or other functions) • Undervoltage detection • A receiver can be powered by 5V •



## 1.2.1 Version V1.3

1/16

### (only the differences are listed)

automatic Gyro adjustment, i.e. no manual adjustment of resistors required • One-sided assembly - it is now possible to build FlightCtrl much flatter • External connection areas (supply, I2C, etc.) have been enlarged • Optional: second voltage supply 7805 for servo supply (eg for camera tilt servo, targeting 7805 as the first with a cooling surface to the outside, not included) •

Servo and external lighting connected via a pin header • New (compatible) accelerometer sensor • 4-layer design • The transistors (PDTC143) to the outputs SV2 of version 1.3 can only switch 100mA! This corresponds, for example, to half a LED strip (3 pieces of 2x3 LED). •



## 1.2.2 ME Variant

See FlightControl ME • Is not a new version, but as a separate variant parallel to the previously distributed version 1.3 • Quality MEMS gyroscope technology manufactured by Analog Devices • 5 servo outputs • Supply is now a Recom-switching regulator • Optional: 2nd supply voltage for servo output (not included) • Servo and external lighting connected via pin header • 4-layer design • en/FlightCtrlManual 10/13/15 19:17:24

# 2 Micro Controller

Computing and processing is accomplished by a Atmel ATMEGA644 @ 20MHz. This is a low cost and popular 8-Bit-processor.

The criteria for the choice of the micro controller were:

satisfactory performance • good availability • low cost • easy to solder • availability of free development software Sensors •

The flight attitude of a quadrocopter must be controlled electronically. We need different sensors for this.


# 2.1 Gyro Sensors

They measure the angular velocity (rotational speed) of each axis. We need three sensors to stabilize all three axes. These sensors are the most elementary components (-> GyroScope )



# 2.2 Acceleration Sensor

The main function of the acceleration sensor is to measure the actual tilt of the MikroKopter and to support the altitude adjustment. Here we use a three axis sensor. •

Theoretically we could omit this sensor if the quadrocopter should work in the so called Heading-Hold-Mode. ( --> Acceleration Sensor )


# 2.3 Atmospheric pressure sensor

It serves to stabilize the flight altitude. This sensor is optional. The large pressure openings should be closed with adhesive tape where we make a tiny hole with a needle. This protects from false readings due to wind and light. (--> en/heightsensor )

Airpressure sensor at high altitude: If the Mikrokopter is going to be flown at very high altitudes (eg 2500 meters), then it is possible that the airpressure sensor will not operate correctly. The resistors have been calculated for airpressures of 850 to 1100 hpa. At 2500 metes the airpressure will be about 750 hpa. to correct this, solder a 1.5 (to 4.7) kOhm resistor (value dependent upon altitude) parallel to R21.



# 2.4 Interfaces

The controller board communicates with the outside world through different interfaces.


# 2.5 PPM input

Here we connect the receiver. Two wires for the supply voltage and one for the receiver’s R/C sum signal. Compared to a normal servo PPM signal the sum signal contains all the channels sent by the R/C transmitter before they are decoded by the receiver. This signal is available in every receiver but there are only a few where this signal is directly accessible from outside (e.g. the RX3 Multi by ACT). ( --> RC receiver )

3/16

# 2.6 I2C Bus

We connect the BL-ESCs to this bus, which carries the command sequences. The Flight-Ctrl needs our special brushless ESC, to ensure fast communication via the I2C Bus. Standard ESCs cannot be used as they are to slow. The I2C Bus has a clock (SCL) and data (SDA) line. The bus connects all SCL and SDA lines together.


# 2.7 Serial Interface (asynchronous)

Here we connect a PC for testing and calibration. The signal is TTL and not V24. For this reason we need to
connect an interface converter if we want to communicate with the standard serial interface of the PC. Later on this interface can also be used for the communication (asynchronous) with other controllers.


# 2.8 ISP Interface (synchronous)

The ATMEL controller will be programmed via an ISP interface. This interface can be also be used for a fast communication (synchronous serial) with other controllers.


# 2.9 Compass connection

A digital compass can be connected to the PC4 input of the universal connector. en/FlightCtrlManual 10/13/15 19:17:24

# 3 General security notes

We do not guarantee an error free behaviour of the electronics or the software. Despite thoroughful design and verification we will not be held responsable (directly or indirectly) for the flawlessness of the software, the hardware or the informations included. You use the electronics at your own risk (this is also applicable for the PC software delivered). Further on we deny any responsability for colateral damages of goods or people which could arise from the use of this application. It is your own responsability to make a complete system

test.

The MikroKopter

is not a children’s toy. It is too expensive and too dangerous for this. Do not fly over people!

In any case you should contract a special model airplane insurance before the first flight because most ordinary liability insurances will not cover damages caused by model airplanes.



# 3.1 Conditions of use

The use of the whole or parts of the MikroKopter project (hardware, software and documentation) is only allowed for private (non-commercial) use. If you intend a direct or indirect commercial use please contact us
for conditions.

# 4 Setting up the board

4.1 Step 1: Connection and Control of the supply voltage

Before powering up you should once again check the correct position of the voltage regulator IC4 (μA7805) and the diode D1. The supply voltage is connected to the pad J1 (marked „+“ at the switch) and to the pad J2 (marked „-“ close to the switch). It is strongly advised to use a current limited power supply until you know that everything is working correctly. The supply current for the Flight-Ctrl board plus the four BL ESCs is
about 200 mA.

5,0V Test of the digital supply. Check at TP1 to GND. Voltage should be between 4,9 and 5,1 V.

3,0V Test of the analog supply. Check at TP2 to GND. Voltage should be between 2,9 and 3,1 V.


# 4.2 Step 2: Gyro Amplifier Calibration

The outputs of the gyro amp (Pins 8, 7 and 1 of IC2) should show a voltage of about 1,2-1,8V (ideal value would be 1,5V) in idle state (board/copter not moving). The factory adjusted output signal of the gyros may vary slightly, we must therefore sometimes correct the signal.

We need to add the resistors R9 (for TP4), R13 (for TP5) and R17 (for TP3) to increase the value of the signal (the lower the value of the resistor, the higher the output signal). Or we need to add the resistors R29 (for TP4), R20 (for TP5) und R15 (for TP3) to lower the signal (the lower the value of the resistor, the lower the output signal).

Default values for the calibration resistors:

Increasing the amplifier signal: signal value < 0,8V : 150kOhm < 1,0V : 220kOhm < 1,2V : 470kOhm

Lowering the amplifier signal: signal value > 2,2V : 150kOhm > 2,0V : 220kOhm > 1,8V : 470kOhm

6/16

### After a severe crash or irregular movements of the MikroKopter (e.g. pitch is smoother in one direction than the other) the signal should be checked and recalibrated if needed.


# 4.3 Step 3: Programming with the MikroKopter Tool (avrdude)

The software transfer (In System Programming) is easiest with our serial converter ( SerCon ), which contains already an ISP circuit. The PC must have a “real“ serial interface for programming. USB to serial/parallel converters or similar adaptors are definitively not working! The serial converter is connected to the 6 pin header with a ribbon cable. The LED on the converter board will be in an indifferent state (on or off). The Flight-Ctrl board must be connected to the supply voltage for programming.

As an alternative the software can be programmed via USB with an AVR ISP mkII. The description is
available under USB-AVRISPmkII . Another possibility for a later data communication via USB is the USB-TTL-232 adaptor

.

A boot loader is now available for the Flight-Ctrl. Instructions for programming can be found under MikroKopterTool

... 

# 4.4 Step 4: Hardware Test

4.4.1 Test of sensor values

When the controller has been successfully programmed, you can check the sensor values with the MikroKopter

tool. For this procedure you connect the serial converter with the large ribbon cable. The ISP cable must be disconnected for debugging or the jumper must be removed from the converter board.



## 4.4.2 Test of gyro and acceleration sensor data

The board must be put in a horizontal position and switched on (or reset), then start the scope option in the MikroKopter

tool (if the scope was already running you should stop it for a moment to reset the zoom range). We observe here only the first five analog values. The other analog values can be switched off via the tab „Scope“ in the MikroKopter tool if the display becomes to difficult to read. en/FlightCtrlManual 10/13/15 19:17:24

7/16

### Now you tilt the board as smoothly as possible to about 45 degrees in direction of the pitch axis. On the scope

you check the signal values. The signal of the pitch integral and the pitch acceleration sensor (here red and yellow) should show a significant value

.

It is important that the overlaid graphs are identical as far as possible.

The same check has to be made on the roll axis (here blue and green):

Then we check the yaw gyro. For this purpose we turn the board around the yaw axis and observe the signal of the gyro. As long as we turn the board there will be a value > 0 which will come back to zero when we stop moving the board.

We check the offset values of the gyros in the virtual display (the values in parenthesis):

For this purpose we click through the buttons in the corresponding menu. The offset values should be around 500 (+-100). In this example the yaw gyro has a problem (178). It must be recalibrated or changed. en/FlightCtrlManual 10/13/15 19:17:24

8/16

## 4.4.3 Test of the Rx signal

In the virtual display we can read the R/C values:

With the R/C control we can adjust the values in the range of ca. -120 to +120.



## 4.4.4 Test of the voltage measurement

In this menu you can check the value of the voltage measurement:

In this example we have 11,3V.

The Rx level is 0 because no receiver was connected.


# 4.5 Step 5: Installation into the MikroKopter

More information on our homepage



## 4.5.1 Synopsis of the connection of other components

4.5.2 Short form:

The arrow on the mounted Flight-Ctrl board points in flight direction • Addressing the motors : 1=front 2=back 3=right 4=left • The direction of rotation of the motors: the left and right motor (roll axis) turn counter clockwise (seen from above) and the front and back motor (pitch axis) turn clockwise. •



## 4.5.3 Connections:

the multi signal from the receiver with a 3 wire servo cable •

a LiPo battery (11,1V ca. 1,5-2,5Ah dischargeable with 15-20C) with two wires of 0.75mm2 minimum (positive=red; negative=black) •

four BL-ESCs with two supply wires of 0.75mm2 minimum (positive=red; negative=black) • I2C Bus for the communication with the Brushless-ESCs •

9/16

# 4.6 Step 6: Control of the MikroKopter (short form)

=== Initial Calibration ===

After building, flashing new firmware or changes to the airframe: Place the MK at a level surface, and make sure it's perfectly level. Store ACC data for this position by applying full-throttle+yaw-right (in mode2 - left stick in upper right corner). -From now on you can start from sloping surface.



## 4.6.1 Switching on the motors

Calibrate the sensors, apply full-throttle+yaw-left (in mode2: left stick in upper left corner) until the buzzer beeps. •

To start push the throttle/yaw lever to the lower right corner until the motors start • The levelling control starts working from a certain throttle value only. •



## 4.6.2 Calibration of the sensors and choice of flight mode setting / parameter
set

For the calibration of the sensors push the throttle/yaw lever to the upper left corner until the beeper beeps and the green LED goes off. This way the controller regards the current gyro values as "levelled". The beeper will tell you which "setting" is currently active. There are 5 possible settings. During the calibration as just described you can choose the appropriate setting with the pitch/roll lever
like this:

Meaning: Pitch-Roll lever left middle = Setting1 ; left upper = Setting2 and so on.

The image below shows greater detail of how the sticks are used to select settings and calibration modes: en/FlightCtrlManual 10/13/15 19:17:24

10/16

## 4.6.3 Switching off the motors

Push the throttle/yaw lever to the lower left corner until the motors stop.

Here you will find a video demo of how to start the motors, calibrate (1 beep confirms setting1), and stop the

motors.



## 4.6.4 Behaviour when loosing Tx or Rx signal

If the Rx signal gets lost during the flight the motors will continue to turn for a few seconds while the MikroKopter

tries to get in a horizontal position. This should (more or less) allow for a controlled descent of the quadrocopter.

# DJI Ace One Introduction

DJI Ace One is an autopilot system for radio

- controlled helicopters, which completely takes the stress out of flying RC helicopters for

both professional and hobby applications. Ace One can be installed in a variety of models, from small electric helicopters to large

ga soline and turbine helicopters.

##  Built

- in f unctions include :

 Integrated tail gyro
The flying direction (YAW) of helicopter will be effected by cross

wind. Ace One system can detect the drifting angle & Speed, and

control the rudder servo to eliminate such influences.
In the case of flying forward in cross

- wind, Tail Gyro can work on

two different modes as the example shown.

 Flybarless rotor head support

 Integrated engine governor for internal combustion engines

 Tilt and roll gimbal stabilization© 201 2 DJI Innovations. All Rights Reserved. 5 | 

# Package Contents

 Main Controller (MC)

The Main Controller is the brain of Ace One . The MC communicates with the IMU,
GPS/Compass, engine governor, servos and RC transmitter to carry out autopilot
functionality. The MC provides a “black box” flight log, and USB interface to read flight logs,

co nfigure Ace One and update firmware from a PC

. (System requirement: Windows XP SP3 or Windows 7)



##  GPS & Compass module (GPS)

The GPS/Compass module includes two status

- indicat ing

LEDs. It should be installed on the tail boom, where there is a clear view of the sky

.



# ×1  IMU

# × 1© 201 2 DJI Innovations. All Rights Reserved. 6 | 

# Mounting and Connection 

# A1 Before you Begin

Fly the helicopter without Ace One and make sure that the helicopter works properly without any autopilot as sistance . To complete this
step, you will need a tail gyro instead of Ace One system . This is a good time to isolate and resolve unwanted vibration s

. IT IS

IMPORTANT THAT YOU SHOULD NOT SKIP THIS STEP.



# A2 Mount the devices on your helicopter

 IMU

 Where? The IMU is best positioned near the helicopter’s center of gravity, where
vibration is relatively low.



###  What orientation? Orient the IMU such that the arrow marked on the above
surface of the IMU faces the sky and points directly forward, backward, left or
right. The sides of the IMU should be precisely parallel to the helicopter body.

DO NOT MOUNT THE IMU UPSIDE

- DOWN.



###  How? Use double

- sided foam tape for secured installation.

1 Check the double

- sided foam tape or Velcro regularly to ensure that the IMU is securely positioned.

2 DO NOT cover the ventilation holes, keep them unobstructed.

3 The IMU module is NOT water

- proof or oil

- proof.


##  GPS & Compass Module (GPS)

 Where? Mount it on the tail boom, between the

rotor

- head and the tail

- rotor. The compass is
sensitive to magnetic interference, so position the

module at least 20 cm from servos and 30 cm from
electric motors or gasoline (petrol) engines. The

GPS is sensitive to vibration interference, so position

the module at least 10 cm from the tail rotor. The

GPS should not be close to the main rotor head

because rotor blades can interfere with GPS satellite
signal, the farther from the center of the rotor disk,

the better.



###  What Orientation? The DJI logo marked on the
GPS should face the sky, with the orientation arrow
pointing directly forward. The GPS is packaged with
a special indication line for mounting for the first

time. The LED status indicators should face the tail

r otor.

1 If you are uncertain whether materials near the GPS are magnetic or not, you can use a compass or magnet to check it.

2 GPS mounting

- support hardware is included in the Ace One package. If however you prefer to use your ow n GPS mount, please make sure that the mount material is NOT magnetic.



##  Main Controller (MC)

 Where? There is no orientation requirement for the MC. Maintain at least a 20

- centimeter

- distance between the MC and the
engine or motor. Choose a mounting location where as shorter servo extension wires are needed as possible. This helps reduce

the risks of ele ctronic interference. Please also m ake sure the USB port is accessible when installing the MC so as to facilitate
software configuration.
After choosing a location to mount the MC , it is recommended that you DO NOT mount the MC until all wirings and software
configurations are completed.

# A3 Connections

 CAN Bus

– Interface for Ace One Module

The Ace One MC uses CAN

- Bus to power and communicate with

other Ace One modules. Three connection ports are provided: two

on the MC and one in

- line connection on the GPS/Compass wire.

Ace One identifies the connected devices automatically without
configuration.



###  GPS module can be connected to either port of MC

.


###  IMU can be conn ected to the MC or to the in

- line port on the
GPS wire. Connect the GPS/Compass and IMU to the MC

. Press & P ull out© 201 2 DJI Innovations. All Rights Reserved. 8 | 

##  Receiver & Servos

STEP1: Set the transmitter to single

- servo CCPM (Futaba: H

- 1; JR/ Spectrum : 1sNORM; Hitec: 1

- Servo 90°).

Connect the receiver to the MC input servo ports. (High voltage receiver is essential

, over 7.4v )

For Camera Gimbal control

For Control Mode Switch
For collective pitch or up/down
For gyro sense adjusting For rudder control

For throttle control
For cyclic pitch or front/back
For cyclic roll or left/right

STEP2: Connect the cyclic servos and throttle servo or ESC ( NOT the rudder servo) to the

Ace One output servo ports using the diagram corresponding to the swash type of
your helicopter

. (High voltage servo is essential, for example, JR HV series.)

For swashplate servos

For throttle servo or ESC

For rudder servo

For Gimbal servos



##  Battery or BEC

Ace One uses the same power source as the servos and receiver; power to all electronics connected to the MC can be supplied by

either servo input or output port s on the MC

. Ace One operates with a power source between 4.8 to 8.4 volts DC

. When choosing a
power source, bear in mind that all servos and Ace One will use that same power source, thus please make sure the power source you

use will also satisfy the servo requirements. A hi gh capacity battery of 4000mAh or above is strongly advised , especially for large scale
electric powered helicopter.

The power consumption of Ace One is 5W maximum (testing condition : 0.9A@5V ). For s ome small scale helicopter s
, the

BEC provided may not be able to supply enough overall power consumption , please use high performance BEC

Ace One Assistant Software

- MOUNTING page STEP1: Select I MU Mounting orientation

STEP2: Fill in the distance between IMU / GPS and the C.G. of

helicopter in X, Y & Z axles, please measure the C.G.
with following method:

a) Adjust your helicopter, and make it balance on X

and Y axle as shown below.

b) The C.G. should be on the extended line of
helicopter main shaft.

c) Hang the helicopter by the tail
and use a plum line to find C.G.
on Z axle. You can use your own

methods to estimate the C.G. of
your helicopter.

*Step c) is not required in pod /boom without
camera mounted, and scale helicopt er. Simply

enter value zero will be sufficient

.

# B3 Flybarless

When system is powered on, you must not move your helicopter or sticks on transmitter until the system initialization is
finished (about 5 second).
Once you changed the Flybarless to “ON”, the AILE and ELEV swash mix ratios in swashplate settings will be disabled, while
[Direction Reverse] button will always be available for AILE and ELEV. After you have set the Flybarless to “ON”, you have

to a djust your swashplate parameters before setting your Flybarless control parameters.

1 You have to adjust flyberless function and test it in M anual M ode first.

2 Don’t try to use Atti. M ode

, GPS Atti. Mode and GPS Cruise M ode until you can fly flybar

- less without any problems.

3 You might need to reduce the control gain of flybarless if you cannot make the helicopter stably hover or fly under Atti.

Mode

, GPS Atti. Mode and GPS Cruise Mode

.

In Ace One Assistant Software, page

- FLYBARLESS:

STEP1: Choose flybarless ON/OFF, you MUST NOT enable
flybarless function for helicopter with flybar, otherwise
the helicopter will be out of control.

When F lybarless is turned on , elevator & aileron will

have stabilization in manual mode.

STEP2: During test flight procedure, pl ease perform the

following configuration procedure.

Gain Parameter range: 20% to 500%
If the helicopter is sluggish, increase it; if the helicopter oscillate back after brake, decrease it. Adjust this parameter 10% increment
time until your control feeling is sharp and the helicopter would not bounce after brak ing

. Note: this parameter will only affect the stability but not control feeling.
Direct Input Parameter range: 3 0% to 300%
This is the direct connect ratio for command stick effect, the rolling speed might not be uniform if it is too high, and also will lead to
quick or sudden change in cyclic response.
Cyclic Rate Parameter range: 20 deg/s to 450 deg/s
This is the helicopter body rolling speed ratio, which determines the maximum rolling speed corresponding to command stick en d
point. The helicopter would response very quickly if it is too high, for example high rate in 3D.
Flybar Weight Parameter range: 20% to 300%
The higher the value, the better the static stability of the helicopter. But, it will increases the sluggish on your control feeling, such as
bank turn, and braking is also not sharp enough, like an large inertia helicopter. Similar to adding weight to blade tip.

# B4 Swashplate

You should finish the setup for your swashplate in M anual M ode

.

In Ace One Assistant Software, page

- SWASHPLATE : STEP1: You have to set the transmitter to single

servo swash (Futaba: H

- 1; JR/Spektrum:1sNORM;

Hitec: 1

- Servo 90° ), and Ace One will do the CCPM

instead.

STEP2: Please make your selection according to your
swashplate type

. IMPORTANT

STEP3: The swashplate can be rotated in 360°, with 1° step

increase or decrease. Not required in most conditions.

STEP4: Click / button, you can reverse the working

Direction of swashplate servos. Servo Trim is in

range

- 100 to + 100, with default value at 0. T he
swashplate must be level

. The Current Output will let

you indicates whether your swashplate servos are on
their center position or not.

If you have enabled Flybarless function, then Swash

Mix ratio settings for AILE (Cyclic Roll) and ELEV
(Cyclic Pitch) will not be available, please read
Flybarless setting for detail. Please read your helicopter ’s manual, and make sure
the swashplate servo linkage and all the mechanical
parts were correctly adj usted before you use the

above function for swashplate level adjusting.

Swash Mix is identical to Tx CCPM mixing, this function is no
longer avaliable on Tx after set to single servo (on Tx). STEP5: Click / button, you can reverse the moving

direction for PITCH (Collective Pitch), AILE (Cyclic
Roll) and ELEV (Cyclic Pitch).

The Swash Mix ratio is 0~100%, which defines the
maximum working range for PITCH (Collective Pitch),
AILE (Cycli c Roll) and ELEV (Cyclic Pitch), similar to
Tx setting.
Suggestion: 35~ 45%

, it can give you soft flying

movement , and easy to configure for the following

parameters

. 

# B5 Pitch and Throttle Curve Set up
We suggest you to use the following pitch curve for
better lifting power and safety descending speed. Throttle curve for electric power,
this is the example for JIVE ESC : Throttle curve for integrated engine ( with
governor function ): STEP2 STEP3

# B6 Tail Gyro

When system is powered on, you must not move your helicopter or sticks on transmitter until the system initialization is
finished (about 5 second).

In Ace One Assistant Software, page

- Tail Gyro: STEP1: Please properly set your rudder servo type before you
connect your tail

- gyro servo to it, otherwise your servo
might be damaged due to incorrect servo type chosen.

STEP2: We have [LimitA] and [LimitB] (Range:

- 140 to +140),

which represent end

- points of the tail rotor pitch. The
initial value for both is 50. Adjust these two limit value,
make sure your rudder servo can work the fu ll range for
your tail rotor pitch, without any mechanical binding.
Otherwise, the performance of the tail

- gyro will be
affected. You can identify which side of the tail rotor
pitch is represented by LimitA / LimitB like this:

1. Set one of them to 0, another to 50.

2. Move your rudder stick on your transmitter.

3. One side of the tail rotor pitch will not move.

4. This side should be related to the LimitA / LimitB
whichever you are giving value 0 to.

STEP3: Move your rudder stick, and check whether the tail rotor

pitch is wo rking to your expected direction. If not, please
change to proper direction. Transmitter related channels Input Operation Description

use Head

- Locking Mode.

STEP5: Gyro Sense setting: Set your gyro sense via transmitter, with the channel which you plug into input port

- G on Ace One MC.

We suggest you start from 45% in [Head

- locking mode] , take off the helicopter

, reduce the Gyro sense if tail got vibrating; if
the tail response too slow and drift then increase it. Land you helicopter and switch to [Rate mode] , then take off the
helicopter again, fine

- tune the rudder servo to make the tail stop drifting and land again. Switch the tail gyro between [rate
mode] and [Head

- locking Mode] by 3 times, then center position of Tx will be recorded, now you finished the gyro sense
setting. You can identify the Tail

- Gyro working mode on the status bar of Ace One Assi stant, but that gyro sense percentage
may not be the same as your Tx reading due to different Tx manufacture. STEP3

# B7 Engine Governor

In Ace One Assistant Software, page

- ENGINE: STEP1: Before using Governor Control mode, fine tune your
Gas/Nitro engine to good condition. Otherwise the
performance would be negatively impacted.

STEP2: Select the operation mode:

 Select [TX Control] for electric motor;

 F or Gas/Nitro engine , select [TX Control] first , and finish

next ste p: set throttle servo working range . T hen select
[Governor Control]

. STEP3: S et throttle servo travel range, move the throttle stick to

For Electric For Gas/Nitro Click to set

Maximum open position [SET

- MAX]

lowest stick throttle Engine idling position [SET

- IDLE]

Throttle hold Cut position [SET

- STOP]
Notice: you must not turn on the throttle

- cut.

STEP4: After three of the throttle positions being set, click

[ TEST ] button above to review your throttle working
range settings. Throttle servo will be forced to stay on
each respective position for about 2 seconds. Repeat

the [ SET ] procedure if any incorrect s

.

If a mistake is made , e.g, STOP position being set between MAX and IDEL , you will be notified by (Wrong), and Engine governor will be force d to work in [Tx Control] mode automatically.

STEP5: A third party engine speed sensor is required for the engine speed governor to function. We suggest using Futaba magnetic

engine speed sensor. You have to adjust the sensor/magnet mounting, and leave a proper space between the sensor head
and magnet. You can check this with the percentage bar at page “ENGINE”, over 60% means the magnet is directly facin g the sensor, and less than 2% means that the sensor is far from directly pointing at the magnet.
Notice: Only ONE magnet can be mounted on cooling fans of the engine.

STEP6: Please refer to user manual of your helicopter and engine, find the following parameters:

 M ain rotor speed, in range: 800 to 2500 RPM ;

 main gear ratio, in range: 1.0 to 20.0;

 Engine RPM, in range: 6000 to 25000 RPM . ( Will be calculated automatically )

STEP7: Gov Gain setting , range: 50% to 300%;

Suggestion: 10 0% for Nitro engine; 1 50 % for gasoline engine;
The higher the gain, the higher the frequency of engine rpm fluctuation

.

Governor STARTS to work in all of the following conditions:

 t hrottle stick position i s higher than 20% from cut

- throt tle ;

 When e ngine speed has been raised above 70 % of set RPM ;

 When e ngine speed sensor works correctly.

Governor STOPS working in either one of the following conditions:

 Throttle stick position lower than 10% from cut

- throttle ;

 Engine speed < 3000 RPM or sensor not working

.

GPS Cruise, GPS Atti. and Atti

. Modes take over the throttle, pitch & cyclic positions at the point of switching from Manual

mode . It is essentially how Ace One knows to maintain throttle relative to rotor RPM, not withstanding Go

- Home function

hence throttle hold other than M anual M ode will not cut the engine or motor. Unless, it is switched back to Manual Mode

##  Base Parameters

 Gain
Range: Front/back & Left/Right 40%

~ 400%; Vertical 50%~250%
If too large, you will find the helicopter oscillating in the
corresponding direction (About 5~10Hz). If too small, the
helicopter will likely to be hard to control.

In GPS Atti. Mode and GPS Cruise Mode , if helicopter drifting
on front/back or left/right direction for 2~5 meters, then increase
10% on the corresponding direction it drift s to until the helicopter
getting oscillation . If helicopter vibr ate on its vertical direction,
then reduce vertical parameter by 10% until it get stable. If
altitude drop and drift happens during sharp braking, then

increase I.D.R

- Vertical in advance parameters.

 MAX Speed Limit ( m/s )

# C1 Digital Compass Calibration

 Why calibrate the compass?

Ferromagnetic substances placed on helicopter or around its
working environment will affect the reading of earth magnetic
for digital compass, it also reduce s the accuracy of the
helicopter control, or even reads incorrect heading.

Calibration will elimina te such influences, and ensure Ace

One system performs well in a non

- ideal magnetic

environment.



##  When to do it?

1 The first time you install Ace One on your helicopter.

2 When the helicopter mechanical setup is changed: a) If the GPS module is re

- positioned.
b) If electronic devices are added / removed /

re

- positioned ( MC , servos, batteries, etc).
c) When the mechanical structure of the helicopter is
changed.

3 If the flight direction appears to be shifting (meaning the helicopter doesn’t “fly straight”).

4 The LED indicat or often indicates abnormality blinking when the helicopter yaws. (It is normal for this to happen
only occasionally.) 

##  Calibration procedure:

STEP1: Enter calibration mode: quickly slide the control mode

switch from Position

- 1 to Position

- 3 for 10 times, and LED
indicator will be constantly on in blue;

STEP2: Calibration in horizontal: rotate you helicopter along with

the horizontal surface until the green light is on constantly,
then go to the next step;

STEP3: Calibration in vertical: while gr een light is constantly on,

hold your helicopter vertically and rotate it along with its

vertical axis , keep rotating until the green light is off,
meaning the calibration is finished.

STEP4: After you finished the calibration, LED indicator will show

whether the calibration was successful or not:

 If white light turns on for 3 seconds, calibration succeed s,

calibration mode will auto e xit ;

 If red light keeps blinking quickly, the calibration has failed.

Slide the control mode switch one time to cancel current

calibration, and then re

- start from step 1 for re

- calibration. 1 Don’t calibrate your compass where there is strong magnetic interference, such as
magnetite, car park, and steel reinforcement
under the ground.

2 DO NOT carry ferromagnetic materials with you during calibration, such as keys or cell phones.

3 You don’t need to rotate your helicopter on a precise horizontal or vertical surface, but keep at

least 45° difference bet ween horizontal and

vertical calibration.

4 Ace One cannot be work in the polar circle. If you keep having calibration failure, it might suggest that
there is very strong magnetic interference around the GPS,
please avoid flying in this area.© 201 2 DJI Innovations. All Rights Reserved. 22 |
