Re: Exemption Request Under Section 333 of the FAA Reform Act and Part 11 of the 

Federal Aviation Regulations 

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, Indiana UAS Services, LLC ("IUS") seeks an exemption from 

the Federal Aviation Regulations ("FARs") listed below and discussed in Appendix A. 

Details of IUS and the Blade 350QX3 ("QX3") sUAS are described in Appendix B. Attached 

as Appendix C is a summary of this request. 

The requested exemption would permit IUS commercial operation of IUS's QX3 (see details 

in Appendix B), which weighs 2.1 lbs. (3.3 lbs with imaging payload), to perform aerial 

surveys and inspections that consist of still photographs, video, and other data acquired by 

onboard sensors. The QX3 produces high quality imagery and data that can be used 

independently or combined with mapping software to produce precision digital contour 

maps of the surveyed area. Applications for these sUASs include inspection of sensitive 

infrastructure including oil and gas pipelines and flare stacks, power lines and towers, wind 

turbines, damage inspections and surveying tasks such as precision agriculture, mining, 

transportation, and forestry. Use of the QX3 for these inspection and surveying applications 

reduces the need to operate conventional aircraft, providing data more quickly, accurately, 

economically, safely, and with reduced environmental impact. 

Operations under the exemption will be subject to strict operating requirements and 

conditions to ensure at least an equivalent level of safety to currently authorized operations 

using manned aircraft and under conditions as may be modified by the FAA as required by 

Section 333. As described more fully below, the requested exemption would authorize IUS 

to perform market research and commercial operations of aerial inspections and surveys 

using the QX3, which at 3.3 lbs. is small in size and powered electrically by battery. The 

QX3 will be operated under controlled conditions at low altitude in airspace that is limited in 

scope, as described more fully herein and it will have automated control features, as 

described below. The IUS QX3 is designed to be operated by one person but under this 

exemption will involve two people: an operator and an observer. The operator is responsible 

for flying the sUAS, monitoring its status and flight dynamics while maintaining visual line of 

sight, and keeping the flight within the specified factory limits (in terms of wind, flight range, 

battery life, etc.) to ensure safe operation of the sUAS itself. The observer is responsible for 

monitoring the airspace for other aircraft and hazards and communicating with the operator 

before and during flight as necessary to ensure safe separation from these aircraft and 

Page 1 of 18 
hazards. The operator also will be an individual who has passed an FAA approved or 

equivalent ground training exam and authorized IUS training program for the QX3. Finally, 

the airspace in which the QX3 will operate will be disclosed to and approved, as needed, by 

the FAA in advance. 

IUS respectfully submits that because this small, unmanned aerial system -the QX3- will 

be used in lieu of comparatively hazardous operations now conducted with fixed wing and 

rotary conventional aircraft, the FAA can have confidence that the operations will achieve at 

least an equivalent level or greater level of safety. Approval of this exemption would thereby 

enhance safety and fulfill the Secretary of Transportation's (the FAA Administrator's) 

responsibilities under Section 333(c) of the Reform Act to "establish requirements for the 

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

THE APPLICABLE LEGAL STANDARD UNDER SECTION 333 

IUS submits that grant of this exemption application for use of the QX3 in surveying and 

aerial inspection operations will advance the Congressional mandate in Section 333 of the 

Reform Act to accelerate the introduction of sUASs into the national airspace system 

("NAS") if it can be accomplished safely. This law directs the Secretary of Transportation to 

consider whether certain sUASs may operate safely in the NAS before completion of the 

rulemaking required under Section 333 of the Reform Act. In making this determination, the 

Secretary is required to determine which types of sUASs do not create a hazard to users of 

the NAS or the public or pose a threat to national security in light of the following: 

•The sUAS's size, weight, speed, and operational capability; 

•Operation of the sUAS in close proximity to airports and populated areas; and 

•Operation of the sUAS within visual line of sight of the operator. 

Reform Act§ 333(a)(1). If the Secretary determines that such vehicles "may operate safely 

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

operation of such aircraft in the national airspace system." /d. §333(c) (emphasis added). 

The Federal Aviation Act expressly grants the FAA the authority to issue exemptions. This 

statutory authority, by its terms, includes exempting civil aircraft, as the term is defined 

under §401 01 of the Act, from the requirement that all civil aircraft must have a current 

airworthiness certificate and those regulations requiring commercial pilots to operate aircraft 

in commercial service: 

The Administrator may grant an exemption from a requirement of a regulation prescribed 

under subsection (a) or (b) of this section or any of sections 4470244716 of this title if the 

Administrator finds the exemption is in the public interest. 

49 U.S.C. §44701 (f). See also 49 USC §44711 (a); 49 USC §44704; 14 CFR §91.203(a)(1). 

The grant of the requested exemption is in the public interest based on the clear direction in 

Section 333 of the Reform Act; the additional authority in the Federal Aviation Act, as 

amended; the strong equivalent level of safety surrounding the proposed operations; and 

the significant public benefit, including enhanced safety and cost savings associated with 

transitioning to sUASs for surveying and aerial inspection applications. Accordingly, the 

applicant respectfully requests that the FAA grant the requested exemption without delay. 

Airworthiness of the QX3 

A critical element of the exemption application involves evidence of the airworthiness of 

IUS's sUAS including the QX3. IUS believes the QX3 has demonstrated a history of safe 

and reliable flight operations. The specific QX3 intended for use by IUS under this 

exemption is serial number 2146178058 and is registered with the FAA Civil Aviation 

Registry as N5885J. 

The operating documents for the QX3 system consist of: 

• 350 QX3 Instruction Manual 

• DX8 Instruction Manual 

Both of these manuals are attached. 

Page 3 of 18 
The QX3 also has a significant set of automated features to ensure safe takeoff, flight and 

landing in many conditions, further details of operation can be found in Appendix B. 

Mandatory Operating Conditions 

Grant of the exemption to IUS will be subject to the following mandatory conditions, which 

are based upon operating conditions set forth for operation of sUAS by public entities 

pursuant to Certificates of Authorization, with additional restrictions: 

•All operations to occur in Class G airspace. 

•Operations to avoid congested or populated areas 

•Operations to be conducted over private or controlled access property. 

•Permission from land owner/controller required before commencing any flight. 

•Operations to occur during Visual Flight Rules Meteorological Conditions (VMC). 

•Aircraft to remain within Visual Line of Sight (VLOS). 

•VLOS guaranteed with a cylinder of operation around operator of% nautical miles (NM). 

•Cylinder walls may be expanded by observer with ability to control aircraft. 

•Operations to occur during daylight hours. 

•Above Ground Level (AGL) altitude to be restricted to 400 feet. 

•All operations conducted in vicinity of airport to remain more than 2.5 NM from centerline 

azimuth of runway centerline measured from runway thresholds. 

•Operator will file a NOT AM for each flight. 

•All required permissions and permits will be obtained from territorial, state, county or city 

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

agencies. 

•All operations will include one pilot for flight control and one observer for VLOS 

enhancement of surrounding area near the aircraft 

Operator Requirements 

IUS respectfully proposes that operator requirements should take into account the 

characteristics of the particular sUAS. Certain sUASs, such as IUS's QX3, are 

characterized by a high degree of preprogrammed control and various built-in technical 

capabilities that limit the potential for operation outside of the operating conditions set forth 

above. The QX3 sUAS also provides many built-in functional and safety features to assist 

the operator in safe and reliable operation. 

QX3 navigation aids including landing zones and flight areas that may be designated to 

ensure the QX3 operates only within user specified flight parameters. All flight operations 

are GPS controlled making the system easy to navigate, and the flight control system also 

employs a variety of sensors to ensure high stability and reliability in challenging weather 

conditions. At all times during flight operations, the operator can interrupt a pre programmed 

flight and take immediate control. 

Additional automated safety functions and safety enhancing features of the QX3 include the 

following: 

•Automated preflight system performance checks 

•User preflight checklist 

•Automated condition or fault detection, warnings, and predefined responses to a number 

of flight and system conditions. 

Page 4 of 18 
grant of the exemptions requested herein, including exempting IUS from the requirements 

of Part 21. 

The QX3's satisfaction of the criteria set forth in Section 333 of the Reform Actsize, weight, speed, operating capabilities, lack of proximity to airports and populated areas, 

operation within visual line of sight, and national security - and its showing of an equivalent 

level of safety as it may relate to the requirement for a pilot's license, provide more than 

adequate justification for the grant of the requested exemptions allowing IUS commercial 

operation of the QX3 in surveying and aerial inspection operations. 

Very truly yours, 

Jack Morton 

Indiana UAS Services, LLC 

Page 6 of 18 
Additional automated safety functions and safety enhancing features of the QX3 include the 

following: 

•Auto detection of lost GPS warns the pilot and initiates an immediate landing. 

•Low battery on the QX3 triggers a Non-Fatal Warning alarm to return home, land and 

replace the battery 

•Very low battery on the QX3 triggers a Fatal Error alarm and initiates an emergency high 

speed descent landing. 

•If the QX3 detects a lost link to the ground station the vehicle will perform its predefined 

Non-Fatal Condition Response. 

Given these safety features, IUS proposes that operators of the QX3 should not be required 

to hold a commercial or private pilot certification. Instead, operators should be required to: 

•have successfully completed, at a minimum, FAA private pilot ground instruction and 

passed the FAA Private Pilot written examination or FAA recognized equivalents including 

ICAO issued commercial, private license and ground school; 

•have completed IUS's training program for operation of the sUAS (described in Appendix 

B). 

IUS notes that the FAA has found that safety factors permitted operation of sUASs by 

operators with these qualifications in the case of operations pursuant to public COAs where 

the mandatory operating conditions specified above are present. See Federal Aviation 

Administration, Notice N8900.227, Unmanned Aircraft Systems (UAS) Operational 

Approval, at 2021 (July 30, 2013). The FAA has the statutory authority, granted at 49 

U.S.C.§44701 (f) to waive the pilot requirements for commercial operations. 

Given these conditions and restrictions, an equivalent level of safety will be provided by 

allowing operation of the QX3 without a private pilot's certificate or a commercial pilot's 

certificate, under the conditions set forth herein. 

The risks associated with the operation of the QX3 (given its size, speed, operational 

capabilities, and lack of combustible fuel) are so diminished from the level of risk associated 

with private pilot operations or commercial operations contemplated by Part 61 with 

conventional aircraft (fixed wing or rotorcraft), that allowing operations of the sUAS as set 

forth above meets or exceeds the present level of safety provided under 14 C.F.R. § 

61.113(a) & (b) and does not rise to the level of requiring a commercial pilot to operate the 

aircraft under§ 61.133(a). 

14 C.F.R. § 91.7(a): Civil aircraft airworthiness. 

This regulation requires that no person may operate a civil aircraft unless it is in airworthy 

condition. Should the exemption be granted allowing commercial operation of the QX3 

without an airworthiness certificate, no standard will exist for airworthiness of the QX3. 

Given the size of the aircraft and the previous COAs issued, an equivalent level of safety 

will be achieved by ensuring compliance with the IUS operating manuals prior to each flight. 

14 C.F.R. § 91.9(b)(2): Civil Aircraft Flight Manual in the Aircraft. 

Page 9 of 18 
14 CFR § 91.119: Minimum Safe Altitudes 

Section 91.119 establishes safe altitudes for operation of civil aircraft. Specifically, 

91.119(c) limits aircraft flying over areas other than congested areas to an altitude of 500 

feet above the surface, except over open water or sparsely populated areas. In those 

cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, 

or structure. 

As set forth herein, the QX3 will never operate at higher than 400 feet AGL. It will, however, 

be operated to avoid congested or populated areas. Because survey and aerial inspection 

work must be accomplished at relatively low altitudes and at altitudes less than 500 feet 

AGL, an exemption from Section 91.119(c) is needed. 

The equivalent level of safety will be achieved given the size, weight, speed, and material 

with which the QX3 is built. Also, no flight will be taken without the permission of the land 

owner or those who control the land. Because of the advance notice to the landowner, all 

affected individuals will be aware of the flights. Compared to aerial survey operations 

conducted with aircraft or rotorcraft weighing far more than 3.3 lbs. and carrying flammable 

fuel, any risk associated with these operations will be far less than those currently allowed 

with conventional aircraft operating at or below 500 feet AGL. Indeed, the low altitude 

operations of the sUAS will maintain separation between these sUAS operations and the 

operations of conventional aircraft that must comply with Section 91.119. 

14 C.F.R. § 91.121(a) & 14 C.F.R. § 91.205: Instrument Requirements 

These regulations require each aircraft to have a set of operable instruments available for 

the pilot to reference during flight. Since there is no pilot on board, there would be no use 

for these instruments even if they could be incorporated into such a small platform. 

The only information provided by these instruments that would be relevant to a UAS 

operator would be AGL altitude. Before engine startup in the QX3, a GPS position is 

established as zero AGL. As the QX3 climbs, a highly accurate AGL GPS position is 

maintained and preprogrammed altitude limits are enforced. IUS intends to have this 

altitude limit set at 400' at all times. 

14 C.F.R. § 91.151(a): Fuel Requirements for Flight in VFR Conditions 

This regulation prohibits an individual from beginning "a flight in an airplane under VFR 

conditions unless (considering wind and forecast weather conditions) there is enough fuel to 

fly to the first point of intended landing and, assuming normal cruising speed - (1) During 

the day, to fly after that for at least 30 minutes, or (2) At night, to fly after that for at least 45 

minutes." 

The QX3 batteries provide approximately 40 minutes of powered flight. Without an 

exemption from § 14 CFR 91.151, the sUAS's flights would be limited to approximately 10 

minutes in length. Given the limitations on its proposed operations and the location of those 

proposed operations, a longer time frame for flight in daylight VFR conditions is reasonable. 

IUS believes that an exemption from 14 CFR § 91.151 (a) is safe and within the scope of a 

prior exemption. See Exemption 10673 (allowing Lockheed Martin Corporation to operate 

Page 11 of 18 
The QX3 is nearly maintenance free, it performs automatic preflight checks and the failure 

of any check will prevent takeoff. Checks which cannot be done by the system will be 

performed by a qualified person prior to each flight. 

Preflight checklist includes: 

1 . Visual inspection of the airframe 

2. Visual inspections of rotor integrity 

3. Check charge of all batteries (aerial vehicle, command station, radio repeater station) 

An equivalent level of safety will be achieved because the sUAS is small in size, will carry 

no external payload, will operate only in restricted predetermined areas and is not a 

complex mechanical device. As provided in the Instruction Manual, the operator of the QX3 

will ensure that the sUAS is in working order prior to initiating flight, perform required 

maintenance, and keep a log of any maintenance that is performed. Moreover, the operator 

is the person most familiar with the aircraft and is best suited to maintain the aircraft in an 

airworthy condition and to ensure an equivalent level of safety. 

The QX3's Maintenance guidelines ensure an equivalent level of safety to the maintenance 

requirements in Part 91. In addition, any component failure detectable by the system will be 

reported to the control station and will cause the UAV to perform a Fatal Condition 

Response (FCR) or Non-Fatal Condition Response (NFCR), depending on the type of 

failure.

Physical Characteristics 

Measurements- 22" diameter 

Weight -2.1 lbs (3.3 lbs with imaging payload) 

Fuel- Lithium polymer batteries are self-contained, high duration systems with "SMART" 

intelligence onboard. This includes cycle charge times, locations, GPS antenna, chemical 

management, and real-time data feeds to ensure maximum flight duration and subsystem 

safety processes. Charging is done via a dedicated battery charger and can be charged via 

standard wall outlet, or via a vehicle. 

Landing style/type- Autonomous vertical lift 

Propulsion System 

•Engines- The QX3 is powered by 4 electric brushless DC motors. 

•Batteries - Lithium polymer batteries are self contained high duration systems with 

SMART intelligence onboard. This includes cycle charge times, locations, GPS antenna, 

chemical management, and real time data feeds to ensure maximum flight duration and 

subsystem safety processes. Charging is done via a dedicated battery charger and can be 

charged via standard wall outlet, or via a vehicle. 

Performance Characteristics 

•Maximum Altitude- Software limited to 400' 

•Maximum Endurance- 40 minutes 

•Maximum Range- 600' 

•Maximum Speed- 20 MPH 

•Weather Minimums- 500' below reported ceiling 

•Winds Maximum - 10 MPH sustained 

•Minimum visibility- 1 SM 

•Icing conditions- no icing conditions 

•Precipitation- no visible moisture 

Maintenance- The UAS is nearly maintenance free, it performs automatic preflight checks 

and the failure of any check will prevent takeoff. Checks which cannot be done by the 

system will be performed by a qualified person prior to each flight. 

Preflight checklist includes: 

• Visual inspection of the airframe 

• Visual inspections of rotor integrity 

Page 15 of 18 
Redundant Systems- The UAS combines the input from a multitude of sensors. Even 

though the data from all sensors is required for optimal system performance, a single 

sensor malfunction is likely to result in degraded performance rather than leading to a 

catastrophic failure. 

Emergency Procedures and System Failures 

Failure Handling- The UAS has extensive failure detection and handling capabilities. All 

failures are deeded to be either fatal or nonfatal. Failures classified as fatal result in a Fatal 

Condition Response (FCR) and failures classified as nonfatal result in a Non-Fatal 

Condition Response (NFCR). 

Sensor Failure- Failure of onboard flight instruments/sensors will degrade the UAS 

performance and will result in either a FCR or a NFCR, depending on their severity. If the 

UAS becomes unstable due to sensor failure, it will stop all four motors and free fall to avoid 

a fly away condition. 

Motor Failure- The UAS flight performance will degrade significantly if one or more motors 

fails. 

Airframe Failure - If airframe is damaged in ways that impacts flight characteristics, the 

UAS will behave similar to if an on board flight instrument failed. 

Navigation System Failure- In a navigation system failure, degraded GPS will result in 

FCR or NFCR's depending on failures. 

Power Failure- A complete battery failure which results in power loss to the UAS will result 

all four motors stopping and free fall. 

Low Battery Condition- Operator will be alerted of a low battery condition and will land 

the aircraft as soon as able. 

Line of Sight Loss -All flight operations will be conducted with the UAS within visual sight 

of the pilot. If the pilot's view becomes obstructed and line of sight is lost, the pilot may 

instruct the UAS to hover in place until line of sight is reestablished, to return to the takeoff 

position, or to land at the current position. 

Security 

The system and communication links are encrypted by the manufacturer's proprietary 

software.

Low Voltage Cutoff (LVC) 

Low voltage cutoff (LVC) protects the Li-Po battery from over-discharge in flight 

and activates when the battery reaches a preset value. When the battery is 

discharged to the cutoff point, the aircraft will display rapidly flashing red, green 

and blue LEDs to warn you it's time to land. When you see this LED code, land 

immediately to prevent over-discharge and damage to the battery. 

When the LVC is activated, you have approximately 2 minutes until the battery is 

depleted and can no longer maintain a hover. Repeated flying to LVC will damage 

the battery.

GPS Functionality 

To acquire a reliable GPS signal, it is important the 350 QX3 has a clear view of 

the sky. Obstructions that can affect the aircraft's ability to acquire an acceptable 

signal include: 

• Flying close to or around tall/big buildings 

• Flying under dense vegetation 

• Flying indoors or under a structure 

If you cannot acquire a GPS lock at startup, the motors cannot be started in either 

Smart Mode or AP Mode. You will have to re-bind the quadcopter with the GPS 

functions turned off to allow you to start the motors for flight (see the Binding. 

section). It is not possible to use Smart Mode without having GPS enabled. If the 

350 QX3 is initialized with GPS disabled, it will default to AP Mode without position 

hold, but will still be capable of altitude hold. 

If you lose the GPS signal while flying, the aircraft will not have Stick Relativity, the 

SAFE Circle'M feature, Position Hold or Return Home functions available. We recommend maneuvering the 350 QX3 by steering with forward elevator and rudder only 

if GPS signal is lost. 

A · CAUTION: Do not attempt to fly the 350 QX3 with GPS enabled while 

LU indoors or in a location where the GPS signal is known to be poor, as loss 

of signal could result in a crash. 

GPS Functions 

(see the Binding section for turning GPS functions ON and OFF) 

With GPSON 

• If the 350 QX3 took off with GPS lock and a home position set, when Return 

Home mode is activated the quadcopter will fly back to the start position 

(maintaining altitude along the way), then reduce altitude to land. 

• If the 350 QX3 loses GPS lock while flying in Smart, AP or Return Home 

mode, the LED will flash green, purple or red, depending on which flight mode 

you are currently using. The 350 QX3 will default to a stable flight mode with 

similar control response to AP Mode without the availability of position hold. 

• If the 350 QX3 deviates too far from its intended GPS path when in Return 

Home mode, it will descend using the barometric pressure sensor to maintain 

the descent rate. 

• Once the 350 QX3 has landed in Return Home mode, it will stop the motors. 

With GPS OFF 

• The LED will show solid white. 

• The flight mode available will be similar in control response to AP Mode 

without the availability of position hold. 

• Altitude hold will function normally. 

Loss of GPS Signal 

If the 350 QX3 loses GPS signal in flight, it will respond according to the 

following conditions: 

Smart Mode: (Green flashing LED) 

If the 350 QX3 loses GPS signal in flight while in Smart Mode the LED will 

flash green. The stick relativity feature of Smart Mode will not function. The 

350 QX3 will follow the control stick input direction relative to the position and 

orientation of the aircraft rather than the position of the pilot, similar to the 

control response in AP Mode. Return home will not function. The aircraft will 

still use the pressure sensor to maintain altitude and control rate of descent. 

If GPS signal is reacquired, after receiving 5-10 seconds of reliable GPS 

signal, the Smart Mode functions return. 

AP Mode: (Purple flashing LED) 

If the 350 QX3 loses GPS signal in flight while in AP Mode the LED will flash 

purple. The quadcopter will not enter GPS position hold when the right stick is 

returned to center. Return home will not function. If GPS signal is reacquired 

after receiving 5-10 seconds of reliable signal, AP Mode functions return. 

Loss of Transmitter Signal 

If the transmitter signal is lost for any reason, the 350 QX3 will respond 

according to the following conditions: 

• If the motors are stopped, the 350 QX3 will disarm. 

• If the motors are turning but the 350 QX3 is not flying, it will stop the motors 

and disarm. 

• If the 350 QX3 is flying and has a good GPS lock with a home position set, it 

will activate the Return Home function (rapid red flashing LED) upon the loss 

of the transmitter signal. 

• If the compass is faulty, not connected or if there is no GPS lock, 

the 350 QX3 descends slowly when the transmitter signal is lost. 

• If the pressure sensor is not working, the 350 QX3 reduces power to 

control the decent when the transmitter signal is lost.

Flying the 350 QX3 

Throttle stick 

Takeoff 

The throttle control for the 350 QX3 changes the altitude . 

of the quadcopter by moving the throttle stick above or 

below half throttle. As you move the throttle stick above 

half, the quadcopter will climb. As you move the throttle 

stick below half, the quadcopter will descend. The farther 

away from half you move the throttle stick, the faster the 

quadcopter will climb or descend. 

To takeoff, slowly advance the throttle to slightly above 

half. The 350 QX3 will slowly climb. When the quadcopter 

reaches the desired height, ease the throttle back to half 

to hold that altitude. 

Explore the flight envelope of the 350 QX2 AP in 

Smart Mode without fear of losing orientation. See 

the diagrams in the Flight Modes Explained section for 

more details on the aircraft's function in Smart Mode. 

In Smart Mode, the direction the aircraft is pointing 

does not affect the control, and the aircraft's response 

relative to you (the pilot location) does not change with 

orientation. AP Mode operates more like a conventional 

RC helicopter or multicopter. 

NOTICE: If you begin to lose control, release the control 

sticks and the model will self-level. 

Pay close attention to the LED while flying. If at any time 

the LED indicates the flight battery voltage is low (below 

1 0.6V), as shown In the LED code section, land the 350 

QX3 immediately and charge the flight battery. 
Landing 

To land the 350 QX2 AP there are two options: 

• Guide the aircraft to where you wish to land. Slowly 

reduce the throttle below half to descend and land. 

When the quadcopter has landed, lower the throttle 

completely and press the bind button to stop the 

motors. 

• Activate the Return Home function to return the 

350 QX3 to the assigned home location and land 

automatically. 

h.. CAUTION: Do not activate the Return Home 

LU function if the 350 QX3 is showing the low 

battery indication. Manually land the aircraft 

immediately. 

Return Home 

NOTICE: Return home will only function if the 

350 QX3 has GPS lock. 

• When this feature is activated, the LED will rapidly 

flash red. 

• The 350 QX3 will fly back to its assigned home location and land. After landing, the motors may take up 

to 5 seconds to stop. 

• The return home function may be cancelled by 

switching back to Smart or AP Mode using the flight 

mode switch. 

• To restart the props after landing in Return Home, 

move both transmitter sticks to the bottom inside 

corners and then back to center. 

A. CAUTION: The 350 QX3 will not recognize the 

£ll SAFE Circle feature when Return Home is used. 

Activating Return Home may cause the 350 QX3 to 

fly directly over the pilot if the aircraft was flown to a 

position behind where the pilot was standing when the 

home position was established. 

After Your Flight 

1. Turn off the power switch on the 350 QX3. 

2. Turn off the power to your transmitter. 

3. Unplug and remove the battery from the 350 OX3. 

Recharge your battery following the charging 

warnings and instructions. 

A CAUTION: Always disconnect the U-Po batL.U tery from the aircraft when not flying to avoid 

over-discharging the battery. Batteries discharged to a 

voltage below the lowest approved voltage may become 

damaged, resulting in loss of performance and potential 

fire when batteries are charged. 

Location alert 

The motors will beep under the following conditions: 

• At any time the props stop spinning after they have 

been initialized. 

• After 30 seconds of no throttle input (waiting armed 

on the ground). 

This will alert the pilot to the location of the aircraft if it 

lands in a location with low visibility. 

Beeping will continue until the battery can no longer 

supply enough power to the motors. 

If the quadcopter crash lands and one or more motors 

are stopped by an impact, the quadcopter enters 

emergency mode. The LED will flash white and the 

motors will beep loudly.

1. Power the transmitter. 

2. Power on the 350 QX3 and face the 

quadcopter pointing North. 

3.Cycle the top left transmitter switch completely 

4 times as shown at the left. 

4. The 350 QX3 indicates it has entered compass 

calibration mode by slowly flashing the LED orange. 

5. When the LED begins to flash rapidly, complete 

all 4 rotations of the 350 QX3 as shown in the 

illustration at left within 30 seconds, rotating the 

quad 45° counterclockwise between each rotation. 

6. Hold the quad level, facing North and check the LED. 

Green = Ready 

Red = Repeat Compass Calibration 

Accelerometer calibration procedure: 

1. Power on the transmitter and 350 QX3 and 

place the quad on a flat, level surface. 

2. While holding the bind switch on the transmitter, 

cycle the top left switch 4 times as shown at the left. 

3.The 350 QX3 will emit a series of slow tones 

followed by a series of rapid tones, indicating the 

calibration has started. 

4. Do not move the 350 QX3 while it performs the 

accelerometer calibration procedure. 

5.When the procedure has completed, the 350 QX3 will 

emit a "happy" tone and the LED will display ~reen 

indicating the calibration was successful. If it emits a 

"sad" tone and the LED displays solid red, repeat the 

calibration procedure. 

Pressure Sensor Calibration 

The pressure sensor is calibrated at the factory on the 

350 QX3. Recalibration should only be necessary if you 

replace the sensor. 

1. Place the 350 QX3 in a cold area. Allow it to remain 

in the cold for 30 minutes or more. 

2.Bring the 350 QX3 out of the cold and into a warm 

area. The greater the difference in temperature 

between the cold and warm areas, the more accurate 

the calibration will be. 

3. Ensure your transmitter is off and then connect a 

flight battery to the 350 QX3Power the 350 QX3 ON 

and let it initialize. The status LED will remain off. 

4. Hold the 350 QX3 upside down until the status LED 

flashes blue, indicating it has entered bind mode. 

5. Set the quadcopter back upright. 

6.Bind your transmitter to the 350QX3 with the rudder 

stick fully to the right. The LED will blink red and blue 

rapidly. Leave the aircraft and transmitter powered 

on and allow the aircraft to warm up for 10 minutes. 

Do not move the aircraft during this time. 

?.After 10 minutes the motors on the aircraft will beep 

to indicate the calibration is complete. Power off the 

aircraft and then your transmitter. 

If the 350 QX3 displays the failed calibration code, power 

off the aircraft and then begin the pressure calibration 

procedure again.

SPEKTRUM'S DXB WITH INTEGRATED 

TELEMETRY 

The DXB is Spektrum's first aircraft system that incorporates integrated telemetry. 

The transmitter's screen displays real-time telemetry including receiver battery 

voltage, flight log data and signal quality. External sensors allow rpm, external 

voltage and temperature to be displayed on screen in real time. Alarms can 

be programmed to warn of low battery, over temperature, exceeded rpm and 

diminished RF signal strength. 

The DXB offers sophisticated programming to meet the demands of even the 

most experienced airplane and helicopter pilots. An easy-to-use rolling selector 

combined with intuitive software makes setting up models quick and easy. The 

DXB is SO-card compatible allowing an infinite number of models to be stored 

and transferred. Plus firmware updates can be downloaded from the 

SPEKTRUMRC.com website providing the user with the latest software upgrades.

CHARGING YOUR TRANSMITTER 

The DXB features a built-in multi-chemistry charger designed to charge 4-cell 

NiMH and 2-cell LiPo batteries at a charge rate of 200mAh. The charge jack on 

the right side of the transmitter is non-polarity-critical, allowing you to use any 

type of 12-volt supply to charge the battery regardless of connector polarity. 

Using the included SPMB2000NMTX NiMH battery pack, you should plug the 

included 12-volt ACto DC power supply in for 10 to 12 hours to fully charge 

the battery. 

& CAUTION: Never plug in a peak detection or fast charger into your 

DXB as this could damage the internal charge circuit. Use only a 12V DC 

source. 

With the transmitter power turned off, plug the included 12 volt power supply 

into a wall outlet. Then plug the male charge plug into the charge jack. The blue 

LED on the front of the transmitter will illuminate. When charging the optional 

SPMB4000LPTX, a full charge can take up to 30hrs depending on the initial 

charge state of the battery. When charging a LiPo, the blue light will turn off 

when the charge cycle is complete. 

SPEKTRUM DXB • RADIO INSTRUCTION MANUAL 

*M* 

NIMH/LIPO BATTERY SUPPORT 

The DX8 includes a rechargeable NiMH battery pack. A low battery alarm 

sounds when the battery reaches 4.3 volts. Spektrum offers an optional2-cell 

LiPo battery pack (SPMB4000LPTX) for the DXB. LiPo batteries have a higher 

operational voltage and when switching to a 2-cell LiPo battery in the transmitter, 

it is important to change the low battery alarm to the LiPo setting to prevent 

over-discharging the pack. 

To Access and Change Battery Type 

In the System Setting screen (see page 20 in your manual) rotate the roller to 

select NEXT at the bottom right of the System setting screen. The following 

screen appears. 

Extra Settings 

Batt Alat'"m: 6 . 4V

RECEIVER INSTALLATION 

In gas and glow aircraft install the main receiver by wrapping it in protective foam 

and fastening it in place using rubber bands or l1ook and loop strap. 

In electric airplanes or helicopters, you can use thick double-sided foam tape to 

fasten the main receiver in place. 

Mount the remote in a slightly different location from the primary receiver. This 

gives tremendous improvements in path diversity. Essentially, each receiver sees 

a different RF environment and this is key to maintaining a solid RF link. This is 

especially the case in aircraft with substantial conductive materials (e.g., larger 

gas engines, carbon fiber, pipes etc), which can weaken the signal. 

Using servo tape, mount the remote receiver keeping it at least 2 inches 

away from the primary antenna. Ideally, you should position the antennas 

perpendicular to each other. In airplanes, we recommend mounting the primary 

receiver in the center of the fuselage on the servo tray and the remote receiver to 

the side of the fuselage or in the turtle deck. 

SPEKTRUM DXB • RADIO INSTRUCTION MANUAL 

Y-Harnesses and Servo Extensions 

Do not use amplified Y-harnesses and servo extensions with Spektrum 

equipment. Only use standard non-amplified Y-harnesses and servo extensions. 

When converting existing models to Spektrum, replace all amplified Y-harnesses 

and/or servo extensions with conventional non-amplified versions 

Power System Requirements 

Onboard power systems must provide adequate power, without interruption, 

to the receiver even when the system is fully loaded (servos at maximum flight 

loads). Inadequate power systems are a primary cause of in-flight failures. Some 

components that affect the ability to properly deliver adequate power include: 

the selected receiver battery pack (number of cells, capacity, cell type, state of 

charge), switch harness, battery leads and, if used, the regulator and power bus. 

The AR8000's minimum operational voltage is 3.5-volts. Test the system per the 

following guidelines to a minimum voltage of 4.8-volts during ground testing. 

This will compensate for battery discharging or actual flight loads that are greater 

than ground test loads. 

Recommended Power System Guidelines 

1. When setting up large or complex aircraft with multiple high-torque 

servos, use a current and voltmeter (HAN172). Plug the voltmeter in an 

open channel port in the receiver, and with the system on, load the control 

surfaces on your aircraft by applying pressure with your hand. Monitor the 

current as you load control surfaces. The voltage should remain above 4.8 

volts even when all servos are heavily loaded. 

2. With the current meter in line with the receiver battery lead, load control 

surfaces while monitoring the current. The maximum continuous 

recommended current for a single heavy-duty servo/battery lead is 3 amps. 

Short-duration current spikes of up to 5 amps are acceptable. If your system 

draws more than these currents, you need to use multiple packs of the same 

capacity. with multiple switches and multiple leads plugged into the receiver. 

3. If using a regulator, perform tests for a 5-minute period. A regulator may 

provide adequate short-term power, but this tests its ability to maintain 

voltage at significant power levels over time. 

4. For really large aircraft or complex models, multiple battery packs with 

multiple switch harnesses are necessary. No matter what power systems 

you choose, always carry out test #1. Make sure the receiver is constantly 

provided with 4.8 volts or more under all conditions. 

it, CAUTION: When charging any brand of NiMH battery pack, make sure 

the battery is fully charged. Due to the nature of peak charges and variations in 

charging rates, heat development, and cell types-the capacity reading of a battery 

charged on a fast peak charger may only reach 80% of its nominal value. Use a 

charger that displays total charge capacity. Note the number of mAh put into a 

discharged pack to verify the charge is at full capacity. 

BINDING 

You must bind the receiver to the transmitter before the receiver will operate. 

Binding teaches the receiver the specific code of the transmitter, so it will only 

connect to that transmitter. 

1. To bind an AR8000 to a DSM2 transmitter, insert the bind plug in the BATI/ 

BIND port on the receiver. 

11 
-

Note: To bind an aircraft with an electronic speed controller that powers 

the receiver through the throttle channel (ESC/BEC), insert the bind plug 

into the BAIT/BIND port in the receiver and the throttle lead into the throttle 

(THRO) port. Proceed to Step #2. 

2. Power the receiver. The LED on the receiver will be flashing, indicating the 

receiver is ready to be bound to the transmitter. 

3. Move the sticks and switches on the transmitter to the desired failsafe 

positions (low throttle and neutral control positions). 

4. Press and hold the trainer button while powering on transmitter. 

5. The system will connect within a few seconds. Once connected, the LED on the 

receiver will go solid indicating connection. 

6. Remove the bind plug from the BATI/BND port on the receiver. Power off the 

transmitter and store the bind plug in a convenient place. 

NOTICE: Remove the bind plug to prevent the system from entering bind mode 

the next time the power is turned on. 

7. After setting up your model, rebind the system so the true low throttle and 

neutral control surface positions are set. 

FAILSAFES 

When you bind your transmitter, you are programming the receiver with failsafe 

defaults. If connection is lost between the transmitter and receiver, the receiver 

immediately operates in those preprogrammed default positions. Those positions 

are failsafes. The ARSOOO has three failsafes: SmartSafe Failsafe, Hold Last 

Command Failsafe, and Preset Failsafe. 

SmartSafe Failsafe 

SmartSafe Failsafe is always active in both hold last command failsafe and in 

preset failsafe. SmartSafe is a safety feature on the throttle channel only that offers 

the !allowing benefits: 

• Prevents electric motors from operating when the receiver only is turned on 

(no signal present) 

• Prevents the speed controller from arming until the throttle is moved to low 

throttle position after connection is made 

12 

• Shuts off electric motor and reduces gas/glow engines to idle if signal is lost 

• If throttle is at any position other than low, the ESC won't arm 

• If connection is lost in flight: 

-SmartSafe sets the throttle to the position it was in during the binding 

process. 

How To Program 

SmartSafe is automatically set when hold last command failsafe or Preset failsafe 

is programmed or the system is bound. Note: It's important to have the throttle 

stick in the low position to store low throttle during binding 

To Test 

Confirm the failsafe setting is correct by turning off the transmitter. The throttle 

should go to the preset low throttle position. 

& CAUTION: Make sure the aircraft is restrained on the ground. If failsafe is 

not set, your aircraft might advance to mid or full throttle. 

Hold Last Command 

If you lose connection, all channels except for throttle channel hold last given 

command and the aircraft continues on its path. So, if you were turning when 

connection was lost, your aircraft would continue turning. 

How to Program 

1. Leave the bind plug in the bind port through the entire binding process. 

2. Remove bind plug only after receiver connects to transmitter 

To Test 

Confirm the failsafe settings are correct by turning off the transmitter. All channels 

except tor the throttle should hold the last command. 

& CAUTION: Make sure the aircraft is restrained on the ground. If failsafe 

is not set, your aircraft might advance to mid or full throttle. 

Preset Failsafe 

If the signal is lost, all channels are driven to their failsafe position set during 

binding. 

Preset Failsafe is ideal for sailplanes, as spoliers can be deployed during loss of 

signal, preventing a flyaway. 

How To Program 

1. Insert the bind plug and power on the receiver. 

2. When the receiver LEOs blink indicating bind mode, remove bind plug 

before binding the transmitter to the receiver. 

3. LED lights will continue to blink. 

4. Move transmitter's control sticks and switches to the desired Preset Failsafe 

positions then turn it on in bind mode. 

5. The system should connect in less than 15 seconds. 

NOTICE: Failsafe features vary according to receiver, so if using a receiver other 

than the ARSOOO, consult your receiver's instructions for the fail sales that apply. 

Before flight, ALWAYS confirm your binding is good and failsafe is set. To do 

this, make sure the system is connected, turn your transmitter off. Confirm that 

low-throttle is active. 

& CAUTION: Make sure the aircraft is restrained on the ground. If failsafe is 

not set, your aircraft might advance to mid or full throttle.

SYSTEM SETUP 

The DX8 organizes the programming screens in two separate categories: 

System Setup Mode and Functions Mode. The System Setup Mode contains 

programming that is generally used when initially setting up a model, and 

seldom used at the field. System Setup functions includes Model Type, Model 

Name, Wing Type, (Swashplate Type for Helis) Model Reset. etc. Note: No

Model Match 

The DXB features ModeiMatch technology that prevents operating a model using 

the wrong model memory. This feature can prevent stripped servo gears, broken 

linkages and even a crash due to attempting to operate a model using the wrong 

memory. 

How ModeiMatch Works 

Each individual model memory (30 in total) has its own embedded code 

transferred to the receiver during the binding process. The receiver actually 

learns the specific model memory selected during binding. When bound, it 

operates only when that model memory is selected. If a different model memory 

is selected, the receiver won't connect. At any time you can reprogram the receiver 

to operate with any other model memory by rebinding with the transmitter 

programmed to the desired model. 

1'-1 

MODEL TYPE ~~ 

Model Type programs the selected model memory to function in Helicopter or 

Airplane programming. You should program Model Type first when setting up a

TRIMSTEP ~~ 

The Trim Step function allows servo movement adjustment per click of trim. For 

example you usually want a large trim step (8 to 1 0) for a new model. Each click 

of trim will have a large amount of trim travel so you can quickly adjust an out-oftrim model in flight. Later you can use a finer trim step (1-5) to adjust for precise 

flight. The Trim Step function allows the trims to be common or independent in 

each active flight mode. Many helicopter pilots use independent trims because 

they are automatically active when a flight mode is activated. Important: The 

trim step function has no effect on the overall trim travel, only the total number of 

clicks available. If you select a 0 value in trim step, the trim is turned off.

MODEL COPY ~-~ 

The Model Copy function copies the currently selected model's programming of 

another model memory. Thirty model memories are available. Some of the more 

common uses of the Model Copy function include: 

• Moving the order of models around in model memory so they can be organized 

by category, type, etc. Note: You will need to re-bind alter moving models. 

• Experimenting with the programming lor an aircraft while preserving a copy 

of the original setup. Note: II you want to use the model copy function to try 

two slightly different setups with the same model you will need to rebind the 

receiver each time you switch between model memories. 

• Copying the programming for an existing model over to a new model that 

is similar. Many pilots lind this to be a good way to provide more accurate 

baseline programming lor the new model. For example Vibe 50 w/120CCPM 

mixing, gyro and governor programming provides a good base programming 

lor any other nitro powered 120CCPM mixing helicopter. An Extra 300 with 

dual aileron and elevator servos that is properly programmed with dual flap and 

dual elevator mixing in Wing Type provides good foundational programming 

for another aerobatic airplane with the same basic control system. 

Important: The model memory you are copying to will be over-written by the 

copied programming, permanently deleting any programming that may already exist.

Installing the TM1 DOD 

Mount the TM1000 module near the receiver in a position that allows the 3-inch 

data lead to extend from the receiver's Data port to the Data port on the telemetry 

module. You can use servo tape to secure the TM1 000 module or wrap it in loam 

with the receiver. Plug the Data lead into the TM1000 port marked DATA and plug 

the other end of the lead into the receiver's DATA port. 

NOTICE: Route and secure the antenna away from any metallic or conductive 

materials to give the best range. 

At this point the internal telemetry including the flight log data and the receiver 

pack voltage is fully functional. 

Before continuing, bind the system to the transmitter and confirm the telemetry 

system is functioning. 

To Bind the Telemetry Module and Receiver 

1. Press and hold the bind button on the side of the TM1 000 telemetry module. 

2. While depressing the bind button, power the receiver. The main receiver, 

all attached remote receivers and the TM1000 telemetry module will blink 

indicating the system is in bind mode.

Temperature, Voltage and Optional RPM Sensors 

The TM1000 includes a temperature and external voltage sensors. Optional RPM 

sensors are available for Gas/Glow and electric brush less models to monitor RPM. 

Temperature Sensor 

To monitor the temperature of most any component, secure the sensor on the 

object. It must come into contact with the surface to get an accurate temperature 

reading. You can loop the temperature sensor around the engine's cylinder head 

to assist in tuning an engine. To monitor battery temperature, you can wrap the 

sensor around the battery. 

The mounting position of the sensor, especially on gas or glow engines, will 

result in different temperature readings. So it's important to experiment with 

different positions. 

Installation 

Insert the temperature sensor connector into the port labeled TEMPNOLT. 

The temperature sensor is now active and the actual temperature displays 

on screen.

'.}olts: 0. 1 v 

RPM: 

Temp: 

External Voltage 

External voltage telemetry is commonly used to monitor flight pack voltage or 

you can monitor ignition batteries on gas engine equipped aircraft. You can set 

warnings to prevent over-discharging batteries. 

Installation 

Plug the connector of the voltage sensor into the TEMPNOLT port in the 

Telemetry module. 

Attach the opposite ends of the voltage sensor (stripped wires) to the 

voltage source you wish to monitor. 

Note the polarity (Red=+ positive /Black=- Negative). 

Typically, you can solder the wires to the battery connector. At this point the 

External voltage displays on the telemetry screen. 

Note: A Y-harness is provided if you want to use temperature and voltage 

sensors simultaneously. 

SPEKTRUM DXB • RADIO INSTRUCTION MANUAL 

RPM (optional sensor sold separately) 

Two RPM sensors are available: SPMA9569 for nitro and gas engines, 

SPMA9558 for brushless electric motors. 

Engine RPM Sensor 

Mftll 

The optional engine RPM sensor mounts inside the backplate of aircraft engines. 

The sensor picks up the crankpin as the engine rotates giving accurate RPM. 

Additionally, you can use this sensor as an RPM pickup on any rotating gear/ 

collar or shaft that has a steel setscrew or other magnetic metal by locating the 

sensor within 5 mm of the rotating steel object. 

Note: On some engines you may need to space the sensor further away 

from the backplate. The sensor picks up the crankpin only; on some 

engines if the sensor is too close, it will not distinguish the crankpin from 

the crank weight. 

Installation 

Install the backplate sensor in the backplate. 

Install the connector into the RPM port in the TM1000. 

Testing 

Turn the transmitter and receiver on and scroll to the RPM telemetry screen. 

Rotate the engine rapidly and the RPM should register on the screen. 

The RED LED on the TM1 000 indicates the sensor is picking up properly. 

You may need to adjust the sensor's position to optimize the pickup. Move 

the sensor closer or farther away until you have a reliable RPM pickup. 

19 
Electric RPM Sensor 

The optional electric RPM sensor is designed to be used with any brushless 

motor. The sensor has two leads to attach to any two of the three motor wires. 

This is typically done by soldering. 

Installation 

To install the electric RPM sensor using servo tape, attach the sensor in 

a convenient place that allows the leads to reach the motor wires and the 

TM1 000 telemetry unit. 

Solder the two sensor wires to any two motor leads. 

Plug the sensor lead into the RPM port on the TM1000 telemetry module. 

Testing 

Turn the transmitter and receiver on and scroll to the RPM telemetry screen. 

Run the motor and the RPM should register on the screen. 

The RED LED on the TM1000 indicates the sensor is picking up properly. 

NOTICE: It is necessary to program a matching pole count in the telemetry 

RPM screen to have accurate reading on screen. The motor's pole count is 

normally in the motor manufacturer's instructions or on the manufacturer's 

website. 

FRAME RATE ~~ 

The Frame Rate function allows the selection of 11 ms or 22ms frame rate. When 

a 11ms frame rate receiver is used, the transmitter defaults to 11 ms frame rate. 

This fast frame rate is not compatable with some types of analog servos and the 

Frame Rate screen allows the selection of a 22ms frame rate when a high frame 

rate receiver is being used with analog servos. 

To access the Frame rate Function 

Press and hold the roller while turning on the the transmitter. When system setup 

appears on screen relese the roller. The DXS is now in System Setup mode. 

Rotate the roller to highlight Frame Rate then press. 

The following screen appears:

TRAINER ~,......~ 

The DXS features a programmable trainer function with three trainer modes. The 

transmitter assigns the trainer function to the trainer button. The function activates 

when the switch is depressed and one of the three trainer modes is selected. The . 

three trainer Modes include: 

Inhibit 

In Inhibit you can use the transmitter as a slave only. However, the slave 

transmitter must have the same programming as the master (e.g., servo 

reversing, travel adjust, sub-trim, trims). 

Programmable Master 

With Programmable Master you can program the transmitter to transfer any or 

all channels when you activate the trainer switch. This is ideal tor beginners 

so the student learns control of individual channels (aileron only for example) 

while the trainer maintains control of all other channels. 

Note: When Programmable Master is selected for the master transmitter, 

all settings for the slave transmitter (i.e. Servo reversing, wing type, Sub 

trim. Travel Adjust. Mixing, etc.) must match the master's transmitter 

programming. If two DXS's are being used simply copy and transfer the 

model memory using the SO card from the master's model to the slave. 

The slave transmitter is then programmed to inhibit in the trainer screen. 

Pilot Link Master 

When Pilot Link Master is selected the slave transmitter has control of the 

stick function only (aileron, elevator rudder and throttle) while the master 

maintains control of all other channels and functions including D/R and 

switch positions. This is ideal for complex models as the master maintains 

control of all secondary functions and controls all other channels. 

Slave 

Use Slave mode when flying with the DXB as a slave when the master 

radio has activated its Pilot Link. In this case, there is no need to match 

programming between the slave and master transmitter. 

SYSTEM SETTINGS ~~ 

Use the System Setting screen to establish the overall transmitter setting that will 

apply to ALL model memories. These settings include: User Name. Contrast. 

Mode, Region and Language. If you select Mode One, then Mode One will be 

selected for all30 model memories. Note: Even when models are imported from 

an SD card the system settings in the transmitter will remain. 

To Access the System Settings Function

DIFFERENTIAL 1-:p • 

The Differential function provides precise adjustments of up/down aileron travel 

of each aileron (or elevon if Delta wing is activated). Typically, you can use 

Aileron differential to reduce unwanted yaw characteristics. In aerobatic airplanes 

adjusting differential provides an axial roll (minimum displacement of yaw 

during a roll). You can program up to three Differential values and assign them 

to a switch. Note that positive+ and negative- differential is available; however, 

normally more up aileron travel is required than down aileron.

SWASHPLATE 

The Swash plate screen adjusts the amount and direction of travel for the aileron, 

elevator and pitch functions when you activate CCPM mixing in Swash Type (see 

pages 15-16). This screen also allows an Expo function that compensates for the 

effect of the servo's rotation at extremes of travel. An E-ring function also prevents 

servo over-travel when simultaneous extreme aileron and elevator inputs are given. 

Unless using a linear servo or a type of linkage that eliminates this effect, you 

should turn on the Expo function when any CCPM mix is enabled. Swashplate 

values increase or decrease the overall control travel of the selected channel. For 

example if you increase Pitch value, the travel of all three servos that control pitch 

will increase./! you increase aileron, the aileron and pitch servos will increase. 

Increasing or decreasing this value affects the travel of that function and not the 

individual servo. Note: Negative and positive swashp/ate values are available. 

To achieve the correct travel direction for Aileron, Elevator and Pitch, first use 

the reversing function to set the servo direction on the aileron, elevator and pitch

channels. Do this so that when an aileron input on the transmitter's stick tilts the 

swashp/ate right and left, an elevator input tilts the swashplate fore and aft, and a 

pitch input raises and lowers the swashplate. You synchronize the outputs with this 

function. Then you can adjust swashplate values positively or negatively to achieve 

the overall correct travel direction for aileron, elevator and pitch.

MIXING 

The DX8 offers eight mixes in helicopter model type. You can program a cyclicto-throttle mix to advance the throttle when aileron, elevator and or rudder inputs 

are given. This prevents rpm decay during cyclic and rudder inputs. A Swashplate 

SPEKTRUM DX8 • RADIO INSTRUCTION MANUAL 

Mix mixes Aileron to Elevator and Elevator to Aileron to adjust swashplate timing. 

Six programmable mixes allow the mixing of any channel to any other channel. 

You can assign Mixes to activate in various flight modes as well as with the gear 

switch. Programmable mixes include a trim offset function that adjusts the mix 

crossover point and a trim include function that applies the master's trim to the 

slave channel. 

To Access the Mixing Functions 

With the transmitter on and the main or telemetry screen displayed, press the 

roller. The Function list displays.

control to maintain rpm. At full throttle, programming prevents the throttle from 

overdriving the servo. 

Important: When using a governor, Cyclic to throttle mix is not recommended.

Solution 

• Move transmitter 8 to 12 feet from receiver. 

• Move to an area with less metal. 

• Check model selected and ensure you are bound 

to that model. 

• Rebind your transmitter and receiver. 

• Replace or contact Horizon Product Support 

• Mount main and remote receivers at least 2 

inches apart and perpendicular to each other. 

• Charge batteries. Spektrum receivers require 

at least 3.5V to operate. An inadequate power 

supply can allow voltage to momentarily drop 

below 3.5V and cause the receiver to brown out 

and reconnect. 

• Check the wires and connection between battery 

and receiver. Repair or replace wires and/or 

connectors 

• If stand is depressing bind button, remove from 

stand and rebind. 

• Rebind your system following binding 

instructions 

• Check battery voltage 

• Turn off transmitter when receiver is turned off 

• Move sensors away from backplate 

• Mount sensor behind cylinder head. When 

installing sensors note engine temperature 

with engine properly tuned. Use this as 

reference value. If temperature goes above this 

significantly, the engine is running too low

APPENDIX 

MODE CHANGES 

The DX8 can be easily converted to mode 1, 2, 3, or 4. This conversion requires 

a mechanical and a programming change. (Stick and switch positions for mode 

1 and 2 are illustrated on pages 8 and 9.) Following are detailed instructions on 

making mode changes 

MECHANICAL CONVERSION 

Mechanical conversion is required to switch between modes 1 and 2 or between 

modes 3 and 4. The centering spring for elevator and the friction straps for 

throttle must be engaged on the appropriate gimbal and throttle limiting wedges 

must be swapped. 

Step 1. Carefully pull back the rear grips and side rubber panels and unscrew 

the six Phillips head screws shown. 

Step 2. Remove the back case noting that a wire harness connects the back 

to the main case. Carefully set the main case to the left side of the 

transmitter being careful not to damage the wire harness. 

(Cages are pictured in white for clarification. The cages 

in your transmitter are black.) 

Changing Throllle Friction from One Gimbal to Another 

Step 3. Locate the silver throttle friction straps on both gimbals. Two straps are 

located on each gimbal. One strap engages a serrated section on the 

gimbal giving a ratcheted throttle feel while the other strap engages a 

smooth section on the gimbal giving a smooth friction feel.

USING A FLIGHT LOG-OPTIONAL 

The Flight Log (optional) is compatible with the AR8000 receiver. The Flight 

Log displays overall RF link performance as well as the individual internal and 

external receiver link data. It also displays receiver voltage. 

Using the Flight Log 

After a flight and before turning off the receiver or transmitter, plug the Flight Log 

into the Data port on the ARSDOO receiver. The screen will automatically display 

voltage i.e. 6v2= 6.2 volts. Note: When the voltage reaches 4.8 volts or less, the 

screen will flash indicating low voltage. 

Press the button to display the following information: 

A- Antenna fades on internal antenna A 

B- Antenna fades on internal antenna B (not used on the AR8000) 

L - Antenna fades on the left external antenna 

R- Antenna fades on the right external antenna (not used on the AR8000) 

F- Frame loss 

H- Holds 

Antenna fades-represents the loss of a bit of information on that specific 

antenna. It's normal to have as many as 50 to 1 DO antenna fades during a flight. 

If any single antenna experiences over 500 fades in a single flight, the antenna 

should be repositioned in the aircraft to optimize the RF link. 

Frame loss-represents simultaneous antenna fades on all attached receivers. 

If the RF link is performing optimally, frame losses per flight should be less than 20. 

A Hold- occurs when 45 continuous frame losses occur. This takes about one 

second. If a hold occurs during a flight, it's important to re-evaluate the system, 

moving the antennas to different locations and/or checking to be sure the 

transmitter and receivers are all working correctly. 

Note: Use a servo extension to allow the Flight Log to be plugged in without 

having to remove the aircraft's hatch or canopy. On some models, the Flight 

Log can be plugged in, attached and left on the model using double-sided 

tape.lt is common with helicopters to mount the Flight Log to the side frame.
