IMPORTANT INFORMATION REGARDING WARRANTY

SAFETY WARNINGS AND PRECAUTIONS

Please read our Warranty and Liability Limitations section before building this product. If you as the Purchaser or user are not prepared to accept the liability associated with the use of this Product, you are advised to return this product immediately in new and unused condition to the place of purchase.

LOW VOLTAGE CUTOFF

Protect yourself and others by following these basic safety guidelines.

1. This manual contains instructions for safety, operation and maintenance. It is essential to read and follow all the instructions and warnings in the manual, prior to assembly, setup or use, in order to operate correctly and avoid damage or serious injury.

2. This model is not a toy, rather it is a sophisticated hobby product and must be operated with caution and common sense. This product requires some basic mechanical ability. Failure to operate this product in a safe and responsible manner could result in injury or damage to the product or other property.

3. This model must be assembled according to these instructions. Do not alter or modify the model outside of these instructions provided by Flex Innovations, LLC. as doing so may render it unsafe and/or unflyable. It is your responsibility to ensure the airworthiness of the model.

4. Inspect and check operation of the model and all its components before every flight.

5. If you are not an experienced pilot or have not flown a high-performance model before, it is recommended that you seek assistance from an experienced pilot in your R/C club for your first flights. If you're not a member of a club, the Academy of Model Aeronautics (AMA) has information about clubs in your area whose membership includes experienced pilots.

6. Keep area around airplane clear from such items as loose clothing, jewelry, long hair, or tools as they can become entangled in the fan unit. Keep your hands and body parts away from the fan unit as injury can occur.

7. Never fly in visible moisture, or submerge the airplane or any of its electronic components in water. Permanent damage to electronic components may occur, or corrosion of components may lead to intermittent failures.

LiPo batteries have a nominal (rated) voltage of 3.7V per cell, and fully charged, reach 4.2V per cell. Batteries are designed to be discharged below the nominal voltage, however, if they are discharged below 3.0V per cell, damage will occur and the pack will lose capacity. For best long term battery life, set a timer and land after a time that leaves approximately 15% of the battery's capacity remaining.

Low voltage cutoff is a feature that is built into the Hobby Wing SkyWalker 80A ESC that is designed to protect the connected battery from being discharged too far and causing permanent damage to the cells. Circuitry within the ESC will automatically detect when the input voltage from the battery pack reaches below 3.15V per cell (average) and will remove power to the motor, but still deliver power to the servos so that a safe landing may be made. If the motor begins to lose power rapidly during flight, the LVC has sensed that the total voltage of the pack has dropped blow 3.15V per cell average, and the airplane should be landed immediately.

The following terms are used throughout the product literature to indicate various levels of potential harm when operating this product:

ATTENTION

WARNING

Set to 3:30 for initial flights with 4200mA

DO NOT ATTEMPT RADIO SETUP WITH MOTOR PLUGGED INTO ESC. INADVERTENT POWER-UP COULD CAUSE

DEATH OR SERIOUS INJURY.

TRANSMITTER SETUP

Start with a freshly reset new model memory in your transmitter. Make ONLY the changes shown in the Transmitter Configuration Guide.

The Aura 8 installed in the FlexJet defaults to 3 flight modes that are switched via CH6/Aux 1 in your transmitter. You may need to reassign CH6/Aux 1 to a 3-position switch.

The retracts in the FlexJet are operated via CH5/Gear in your transmitter. You may need to reassign CH5/Gear to a 2-position switch.

Consult your transmitter manual if you have questions on how to change the switch or channel assignments.

The Aura comes pre-programmed with dual rates and expos specifically configured for the FlexJet. For large (greater than 5%) changes in expo or dual rates, it is highly recommended to reset all expos and rates to default in the transmitter, and tune through the Aura Config Tool.

The Aura Config Tool is free to dowload, and can be used on any Windows-based PC or tablet. Download at:

AURA 8 AFCS

The Aura 8 advanced flight control system installed in your FlexJet is a giant leap forward in aircraft flight control system technology. Compatible with virtually every receiver on the market today, the Aura features special configuration for DSM systems via remote receiver connection(s), and serial data connection for Futaba or Hitec S.Bus, Spektrum SRXL, Graupner HOTT (Sum D of 8), JR XBus (Mode B), and Jeti UDI12 (standard) systems, as well as being compatible with traditional receivers via PWM servo connections.

The Aura 8 advanced flight control system in your FlexJet has been pre-tuned for ease of use, eliminating many hours of tedious setup. For the latest Aura features, programs, transmitter downloads, and instructions, please visit http://wiki.flexinnovations.com/wiki/Aura

The Aura is programmable through any Windows based PC or tablet. All dual rate, expo, travel, and assignable mode programs are adjusted inside the Aura through the PC application. An assignable master gain that is OFF by default can be enabled by the Aura application. If desired, assign CH 8/AUX 3 on a proportional dial or slider.

By default, CH6/Aux1 is used to select the 3 flight modes by 3 position transmitter switch. CH5/Gear is used to retract/deploy the landing gear.

Description of Pre-Loaded Aura Flight Modes (FM)

Mode 1 (Gyro Off): Rates are set for general flight (same as

Sport Mode). Exponential is tuned for comfortable flight.

Mode 2 (Sport Mode): Rates are set for general flight (same as Mode 1). Gains are moderate and tuned for comfortable feel/best performance for precision aerobatics. Expo is tuned for comfortable flight.

Mode 3 (High Rate Sport/Advanced Mode): Gains are highest and tuned for sport aerobatics. Rates are set to highest. Exponential is tuned for comfortable flight.

NOTE - Rudder stick movement will also move ailerons and elevator. This is NORMAL, due to pre-programmed mixing in the Aura 8 for knife-edge correction.

Each of the modes has been tuned by the Flex Team to offer a solid start. Because tastes in control feel are unique, if changes in rates and expo are needed, adjustments should be made through the Aura 8, not in the transmitter. Changes in gain value can only be made through the Aura or via master gain (if activated).

Works conveniently with all major radio systems

Accepts signals from DSM Remote Receiver(s), Spektrum SRXL, Futaba S.Bus, Graupner Hott (Sum D of 8), JR XBus (Mode B), Jeti UDI12 (standard), Hitec S.Bus, PPM Stream, or any brand of receiver via male to male servo connectors

RECEIVER INSTALLATION/SERVO CONNECTIONS (CONTINUED)

Spektrum Remote Receivers

Please note, for optimum connection reliability and performance using Spektrum, the Flex Team highly recommends the use of a traditional receiver using SRXL. Remote receivers may still be used, however:

Connect (2) Spektrum Remote Receivers to Mini Port 'A' and Mini Port 'B' at the top of the Aura case.

To bind a DSMX Spektrum Remote Receiver connection, insert a

2A.

bind plug into Aura Port S8.

To bind a DSM2 Spektrum Remote Receiver connection, insert a

2B.

bind plug into Aura port S1 AND S8.

If you are unsure which type of DSM remote receiver you have, start by attempting the bind process with a bind plug in S8. If you continue to have trouble binding, then insert one bind plug in S1, and one bind plug in S8.

Connect the flight battery to the ESC, and the remote receivers should begin to flash, indicating that they are ready to bind. Bind from here as recommended by your transmitter manufacturer.

Once bound (indicated by each remote receiver showing a solid

orange LED), Aura will begin the Auto-Detect process, indicated by flashing/sweeping LEDs on the Aura. Once found, you will see solid orange (power and calibrated sensor) and solid green (valid receiver data) LEDs, indicating the Aura is in its flight-ready state.

Mount your receivers using double sided foam tape, or hook and loop tape. Consult your receiver manual for proper mounting orientations and procedures.

Note: It may be necessary to move the ESC lead to another open

port (such as 'Port B') during the binding precedure. Be sure to

return the ESC lead back to S1 after binding is complete.

Note: There are many JR-branded remote receivers that use

Spektrum DSM2 and DSMX RF protocol. For these, follow the

instructions as Spektrum remote receivers.

Connecting a Traditional Receiver to Aura with PWM Servo Connections

PWM is an acronym which stands for Pulse Width Modulation. A servo will move to a specific angle in a specific direction based on the width of the signal pulse it receives. Most transmitters output a total pulse width of 1.1-1.9ms, with the midpoint being 1.5ms. Lower pulse widths will move the servo to one side of neutral and higher pulse widths to the other side of neutral. In order to utilize this type of receiver connection with your FlexJet, male to male servo leads that connect the corresponding receiver ports to Aura 8 are required. A minimum 6channel receiver is required to set up the FlexJet/Aura 8 with PWM servo connections. Please purchase (1) FPZAU01 Aura 3-piece male

to male servo cable/S.Bus and (2) FPZA1012 Servo Y-Harnesses to complete the PWM connection setup.

Bind your receiver to your transmitter by following the instructions provided by your transmitter and receiver manufacturer. Verify that it is bound by connecting a spare servo to the receiver and verify that it responds to the appropriate input.

With the transmitter and receiver powered OFF, re-wire the Aura and connect to your receiver using the diagram below. Note that the throttle is plugged directly into the receiver.

With the motor unplugged from the ESC, and ALL connections made between Aura and the receiver (observing correct polarity), power on your transmitter and the airplane with the flight battery, ensuring that the airplane is kept stationary. After a few seconds, the LEDs on Aura will sweep back and forth as Aura searches for a valid control signal. Once found, Aura will emit solid orange, green, blue and red LEDs. After the source is found, apply transmitter right rudder to assist Aura with determining your radio type. A solid orange (Aura running), and solid green (Aura receiving valid signal from the receiver) LED is illuminated after which point control of the model is established. This is only required during initial setup.

VERIFY PROPER POLARITY OF ALL CABLE CONNECTIONS PRIOR TO ADDING POWER TO THE SYSTEM

All four (4) PWM male to male connections must be connected AND connected in the proper polarity from receiver outputs

to Aura inputs for Aura to activate servo outputs. (Aileron - S1, Elevator - S2, Rudder - S3, Aux1/CH6 - S4)

WARNING

CAUTION

RECEIVER INSTALLATION / AURA 8 INSTALLATION NOTE

CAUTION

Throughout the manual we will ask you to power up the radio system. In order to assemble your FlexJet properly, It is critical that the receiver is bound to your transmitter and is communicating with Aura 8. Please do not proceed until the Aura 8 emits a solid green LED (Aura received valid signal from reciever) and solid orange LED (Aura has power and calibrated sensor) when powered up. In the event that you are having difficulties with radio or Aura 8 installation please see the following:

For issues with your transmitter and/or reciever, please review your transmitter/receiver manual or contact the manufacturer directly.

For issues regarding Aura 8 please reference the following:

• Wiki page: wiki.flexinnovations.com/wiki/Aura

• Email us at [email protected]

• Contact Aura Support at 866-310-3539

CONNECTING A BATTERY/ARMING THE ESC

Observe the following procedures to safely power up your model after it has been bound.

Lower the throttle stick and trim to their lowest setting and turn on the transmitter. Wait for your transmitter to indicate the radio signal is being broadcast before proceeding.

If a battery is connected to the ESC with the throttle fully open on the active transmitter, the ESC will enter programming mode. If this occurs, simply disconnect the battery, lower the throttle, and reconnect the battery.

Ensure the aileron, elevator and rudder gimbals are centered.

With the airplane on a solid surface, connect the battery to the ESC and wait. The ESC will make the motor emit a series of audible tones during its intialization process.

The ESC will make the motor emit a short, final tone sequence idicating that the ESC is now armed, and the motor will spin in response to throttle stick movement.

Always connect the battery when the throttle stick

and throttle trim is in the idle/cut-off position.

While assembling the FlexJet, ensure motor is disengaged by unplugging all wire leads that connect the ESC to the motor.

Page 10

RETRACTS AND GEAR SEQUENCER OPERATION

The following steps will be required each time the aircraft is powered for flight:

Ensure your radio has Ch5/gear assigned to a 2-position switch.

Hold the FlexJet in a manner that the gear doors and retracts are unobstructed and free to close and open.

Cycle your transmitters Ch5/Gear switch from down to up, then down again waiting about 1 second in each position.

The gear sequencer is now armed and the gear will deploy or retract.

Test the retracts. Ensure the gear/doors open and close without

binding. When satisfied with the result, power off the aircraft.

Please note, Ch5/Gear can be reversed in the transmitter for user preference.

EDF ACCESS HATCH, TAIL PIPE, and EXHAUST NOZZLE REMOVAL

Required Tools and Fasteners:

Remove the two M3x10 Phillips washer head self-tapping screws that secure the EDF access hatch to the fuselage. Remove the EDF

access hatch and place the hatch and screws in a secure location to be used at a later step in the assembly process.

Remove the two M3x25 Phillips self-tapping screws that secure the exhaust nozzle to the fuselage. Remove the exhaust nozzle and

place the nozzle and screws in a secure location to be used at a later step in the assembly process.

VERTICAL STABILIZER INSTALLATION (CON'T)

*Mark rudder tube with felt-tip pen*

10.

Position the FlexJet so that it is level. Standing approximately 10-20 feet (3-7 m) behind the aircraft, visually sight the vertical stabilizer, ensuring the installation is true and perpendicular relative to the fuselage. Use a file to fine-tune the plywood tube mount if needed.

After ensuring the vertical stabilizer is true, remove the stabilizer.

Mark the vertical stabilizer tube at the point where the tube exits the fuselage and remove it from the fuselage.

Mix and apply an appropriate amount of epoxy to the hole in the fuselage for the vertical stab tube and apply a thin coat to the tube that will be inserted into the fuselage. Insert the tube so that it is flush with the inner wall of the fuselage (touching the tape applied in step

1). Use a paper towel and isopropyl alcohol to wipe any excess epoxy off of the rudder tube that extends out of the fuselage and the fuselage itself. Please note, If any excess epoxy remains on the vertical stabilizer tube and/or fuselage it will prohibit a flush fit

of the fin to the fuselage as well as make vertical fin extremely difficult to remove. In addition, if the vertical stabilizer tube extends too far inside the fuselage, it will interfere with the thrust tube.

Re-install the vertical stabilizer per step 3 and re-sight the stabilizer per step 4. It may be helpful to apply low-tack masking tape to the stabilizer and fuselage in a manner that temporarily holds the stabilizer in place as the epoxy cures.

Power on the radio system. Check the mechanical rudder trim by comparing the trailing edge of the rudder relative to the vertical stabilizer.

If adjustment is needed, remove the clevis from the control horn, and turn the clevis. Re-attach the clevis to the control horn and inspect the mechanical trim of the rudder. Repeat this step until the trailing edge of the rudder is centered relative to the vertical stabilizer.

Once satisfied with the mechanical trim of the rudder, apply a drop of blue thread locker at the point where the clevis and control linkage meets.

12.

Inspect the glue joint of the fuselage and vertical stabilizer tube. If satisfied, remove the low-tack masking tape from inside of fuselage.

EDF ACCESS HATCH, TAIL PIPE, and EXHAUST NOZZLE RE-INSTALLATION

*Tape applied at 10 and 2 o'clock *

Required Tools and Fasteners:

Carefully collapse the tail pipe (without creasing) and insert the tail pipe into the fuselage until it reaches the EDF fan housing. Note, the tail pipe is asymetrical and can only be installed in one orientation. Make sure the side with the wider opening is inserted towards the EDF fan housing.

Un-bend the tail pipe. Align the tailpipe with the fan housing, and 'tap' on the tailpipe's aft edge with your palm to help it move forward. Slide the tail pipe over the EDF Fan Housing.

Place the exhaust nozzle over tail pipe onto the fuselage. Secure the exhaust nozzle using a #1 Phillips screwdriver and (2) M3x25 Phillips self-tapping screws. Note, the exhaust nozzle is asymetrical and will only fit the fuselage in one orientation. Do not use

blue thread locker on this connection.

Slide the tail pipe until it is flush with the end of the exhaust nozzle. Once satisfied with the finish, secure the tail pipe to the EDF fan housing using the two included pieces of clear tape at the 2 and 10 o'clock orientation.

Secure the EDF acess hatch to the fuselage using a #1 screwdriver and (2) M3x10 Phillips washer head self-tapping screws. Note, the

EDF access hatch is asymetrical and will only fit the fuselage properly in one orientation. Do not use blue thread locker on this connection.

CENTER OF GRAVITY VERIFICATION

The center of gravity (CG) location for the FlexJet is located at the forward edge of the plastic wing bolt tab and is measured by

lifting the completed airplane upright, with all components installed and the landing gear in the down position. This location was determined from numerous test flights by designer and TopGun Champion David Ribbe.

Setting the center of gravity is one of the most important steps for success, particularly with a new airplane. The FlexJet is a highperformance airplane that can exceed speeds of 100mph. This makes it a very enjoyable aircraft to fly, but if the CG is not within an acceptable range, it will make the aircraft difficult, if not impossible to control. The desired CG can usually be accomplished by moving the flight battery forward or aft.

After flying the FlexJet you may adjust the CG up to 3/16" (4.76mm) forward or aft for personal preference.

The CG measurement should be made with the completed

airframe with all components (batteries, servos, receiver,

linkages, hardware, etc.) installed and the landing gear in the

down position. Failure to do so will result in an inaccurate

NOTICE

measurement.

PRE-FLIGHT CHECKS

To help ensure a successful first flight, as well as many flights after, perform a few simple pre-flight checks to ensure the aircraft is ready for flight.

Verify control surfaces are properly hinged and in good working order. Pinch a control surface between your thumb and fore-finger, and

stabilize the wing with your other hand. Give the control surface a firm pull away from the wing. The control surface should not come unhinged from the wing. Be sure to avoid over-stressing the part, as an aggressive pull may cause the surface to come unhinged even though it is hinged properly.

Verify that all hardware and all other aircraft parts are properly secured. This includes hardware and parts installed by the factory.

Verify your battery is fully charged and in good condition. Avoid using batteries with swollen cells, or batteries that do not charge back

to their full capacity.

Verify the CG is in the proper location, and the battery is secured in place.

Ensure the Aura is on and functioning properly. Power on your transmitter, followed by the aircraft. Ensure the Aura is calibrated

properly and receiving a valid radio source (solid orange + solid green LEDs).

Verify transmitter stick inputs result in the proper control surface movements (reference page 17).

Verify aircraft movement results in proper Aura sensor corrections (reference page 18).

Verify the motor and ESC function properly. Point the aircraft in a safe direction, and away from any objects or limbs that could become

entangled in the fan unit. Hold the aircraft firmly so that you are behind the aircraft. Smoothly advance the throttle to full and back to idle. Listen and watch for any odd or unusual behavior from the motor and ESC.

Page 21

FLYING YOUR FLEXJET

Trimming

The first several flights on your FlexJet should be dedicated to trimming and setup. Fly the airplane at 2/3 power in Flight Mode 2 and trim for level flight. Land, adjust linkages and return transmitter trim to zero, and fly again. Repeat until the airplane flies hands off, straight and level. Trim or sub-trim added via the transmitter will cause trim shifts when different flight modes are selected. To eliminate this trim shift, you have three options: (1) mechanically trim the model by turning the linkage clevises; (2) electronically trim the model via Subtrim Feature in the Servo Ports tab of the Aura Config Tool; (3) digital (non-PWM) receiver users can utilize the "Quick Trim" procedure below.

Trimming the Ailerons

Due to the FlexJet's large flight envelope, if your FlexJet is holding about 1/16th of an inch or more (1.5mm) of aileron trim it is likely that your Flexjet's aileron trim will change with speed changes. To properly trim the roll axis and prevent these trim changes, center the ailerons (mechanically or electronically) and use and one of the techniques below to move the stabilizers in equal amounts in opposite directions to trim the roll axis: (1) mechanically trim the model by turning the linkage clevises; (2) electronically trim the model via Subtrim Feature in the Servo Ports tab of the Aura Config Tool; (3) digital (non-PWM) receiver users can utilize the "Quick Trim" procedure below.

Please reference page 11 to adjust the flying stabilizers.

Pilots using a 'digital' receiver connection can accomplish this easily using the Quick Trim procedure. Start as instructed with the Ailerons perfectly mechanically centered. Fly and trim. Perform the Quick Trim procedure. Aura will put in any AILERON trim (along with Elevator trim) into the tail stabilizers instead of the ailerons, so your ailerons will return to being perfectly centered!

Aura Quick Trim

The Aura 8 features a Quick Trim Mode that eliminates the need for mechanical linkage adjustments during test flights. Aura will learn the trim values from your transmitter, and apply them to the control surfaces the next power-up.

Selecting a Flying Site

Selecting a flying site is critical to a successful flight. Airplanes require a lot more room than other R/C products, therefore, a neighborhood or parking lot is not recommended. A local AMA field is the best location for flying your Flexjet. If no AMA field is available in your area, a large open field with short grass and generous overfly area is the best candidate. Know your overfly area. Ensure that there are no houses, playgrounds, people or other buildings that may be damaged if the airplane were to crash.

Takeoff

Taxi or place the FlexJet on the runway centerline, with the nose pointed into the wind. Select Mode 2, then set throttle trim so that the motor spins at it's lowest RPM without stopping. Smoothly advance the throttle to full while maintaining directional control with the rudder and slight back pressure on the elevator. The FlexJet should lift of smoothly once flying speed is attained. Fly in Flight Mode 2 until the FlexJet is fully trimmed (see special trimming instructions), and you are comfortable with it's handling, then explore the other modes as desired.

Flying

Altitude is your friend on the first flight. Briskly climb to a safe altitude and trim the airplane. The FlexJet should fly straight and level at 1/2-3/4 power with no input from the sticks. Try some basic maneuvers, and slowly progress into the FlexJet's flight envelope as you become more comfortable with the airplane's flight qualities and perfect your setup. Note: if at

any time, such as after gain adjustments, you experience unexpected control system inputs or oscillations, switch to Mode 1, land, and troubleshoot the issue. (Mode 1 turns the sensor inputs off with default programming)

Landing

Be mindful of your flight time and allow adequate battery reserve for a couple of landing attempts, if necessary, on the first few flights. Select Flight Mode 2 and using 0 - 1/4 throttle slow the FlexJet to begin a landing approach. On the upwind leg, toggle Ch5/gear switch to deploy the gear. Visually confirm the gear are fully deployed. Once on final approach, smoothly apply up elevator as required to maintain 0-5 degrees of nose high angle of attack. Use throttle to control the descent speed. Once you are close to the ground, gradually reduce the throttle to idle and begin to smoothly apply up elevator as required to maintain 5-8 degrees of nose high angle of attack. The FlexJet should gently touch down and roll out with minimal elevator input. Remember, you can

always smoothly advance the throttle to full, and make a go-around to set up for another landing. You don't have to

land on the first attempt.

NOTE:

Quick Trim can also be used BEFORE flying to make small changes to adjust the control surfaces before flight.

ENSURE AILERON/ELEVATOR/RUDDER SUB-TRIMS ARE ZERO BEFORE FLYING FOR QUICK TRIM PROCESS

QUICK TRIM IS NOT AVAILABLE TO PWM CONNECTION USERS. IF YOU ARE USING A PWM CONNECTION, YOU WILL NEED TO MECHANICALLY TRIM THE MODEL or use the Subtrim in the Servo Ports of the Aura Config Tool.

Fly the airplane in Flight Mode 2. Trim the aircraft with the transmitter and land. DO NOT CHANGE FLIGHT MODES.

Power off the Aura. Insert a bind plug into Aura Port S3 (you will need to remove the servo lead that is currently in S3). Check the transmitter is on and repower the Aura.

Wait 5 seconds for the Aura to completely initialize. Confirm Quick Trim mode is active by checking the Blue LED is slowly flashing.

Remove the bind plug from Aura Port S3, and re-install the servo that was previously removed into S3. Removing the bind plug stores the current trims in the Aura. The Blue LED will flash quickly after control surface trim values are store. While the trim values are stored in Aura, they are not applied to the control surface(s) until the Aura is repowered.

Remove power from the Aura and center all control surface trims on the transmitter.

Re-power the Aura. The control surfaces are now adjusted for proper flight trim, even though the trim has been centered on the Transmitter. Switch between other Flight Modes to ensure you do not see any changes in trim.

Make sure all power is removed from the FlexJet. Be sure to unplug all three motor wires from ESC for safety.

Turn on your transmitter. Ensure you are on the correct model memory.

Remove the servo lead that is in Aura Port S2.

Insert a bind plug into Aura Port S2.

Power the FlexJet by plugging a battery into the ESC. The LEDs on the Aura will repeatedly double flash orange. This confirms you

have entered Quick Set mode. The Green LED may be flashing, or solid. More information regarding the green LED is below.

Use the Aux1/CH6 switch (assigned earlier for Aura Flight Modes) to select the Expert or Stock Aura configurations.

If the green LED on the Aura is SOLID, the Aura is set to use the STOCK configuration.

If the green LED on the Aura is FLASHING, the Aura is set to use the EXPERT configuration.

You may optionally assign a Master Gain. (Before running Quickset, assign a proportional slider or knob to CH8/Aux3 in your transmitter). Master Gain will default to OFF when Quickset is run. Sweep the CH8 Down and then UP. The RED LED will illuminate SOLID-ON for Master Gain ON, and OFF for master gain OFF. Leave in the desired state/choice and continue.

Once you have selected your configuration, simply remove the bind plug from S2. All LEDs on Aura will be on while Aura is saving the settings. Once saved, the Aura will go back to its previous LED configuration from step 6. Power off the airplane and Aura, and replace the servo lead back into Aura Port S2.

Power on the radio system and verify that all controls function, and that both the transmitter direction test and Aura sensor direction test pass. Familiarize yourself with the new flight modes and their relative switch positions, and enjoy flying with your new flight modes!

The expert program is gyro-enabled in all 3 flight modes. If you wish to use a secondary switch to be able to turn the Aura off, we

recommend using the Wizard in the Aura Config Tool, and setting up a Gyro Kill switch.

AIRFRAME REPAIRS

NOTICE

The FlexJet is molded from durable EPO foam and is repairable with most adhesives. Similar to building and repairing wood or composite aircraft, the correct glue for a given application is critical to the repair holding and not breaking again. For major repairs, such as a broken fuselage, epoxy is preferred because it allows time to correct any misalignment, and is less brittle than CAs. For smaller repairs, such as a cracked control surface or small chunk of material missing from the airframe, regular CA is very effective. The use of odorless (foam safe) CA is not recommended on EPO foam because it is weaker than regular CA, takes a longer period of time to cure and the bond tends to be weaker.

NOTE: Avoid the use of CA accelerant in repairs. It can damage paint and will weaken the bond of the glue. If CA accelerant is used, be

If a part is damaged too badly to be repaired, please refer to Page 3 of this manual for a complete listing of available replacement parts.

mindful of the locations of CA to prevent premature bonding of parts or bonding a hand or clamp to the airframe.

If a crash is imminent, fully reduce the throttle to prevent further damage to the power system and reduce energy to lessen

impact damage.

CRASH DAMAGE IS NOT COVERED UNDER WARRANTY

NOTE: Avoid keeping the aircraft in direct sunlight when not flying. Excessive heat can damage the airplane's structure, and UV light

can permanently discolor decals.

capable of sustained fight in the atmosphere. It may not exceed limitations of this code and is intended exclusively for sport, recreation, education and/or competition. All model fights must be conducted in accordance with this safety code and any additional rules specific to the flying site.

Model aircraft will not be flown:

Exceptions:

In a careless or reckless manner. At a location where model aircraft activities are prohibited.

Model aircraft pilots will:

Yield the right of way to all human-carrying aircraft. See and avoid all aircraft and a spotter must be used when appropriate. (AMA Document #540-D.) Not fly higher than approximately 400 feet above ground level within three (3) miles of an airport without notifying the airport operator. Not interfere with operations and traffic patterns at any airport, heliport or seaplane base except where there is a mixed use agreement. Not exceed a takeoff weight, including fuel, of 55 pounds unless in compliance with the AMA Large Model Airplane program. (AMA Document 520-A.) Ensure the aircraft is identified with the name and address or AMA number of the owner on the inside of affixed to the outside of the model aircraft. (This does not apply to model aircraft flown indoors.) Not operate aircraft with metal-blade propellers or with gaseous boosts except for helicopters operated under the provisions of AMA Document #555. Not operate model aircraft while under the influence of alcohol or while using any drug that could adversely affect the pilot's ability to safely control the model. Not operate model aircraft carrying pyrotechnic devices that explode or burn, or any device which propels a projectile or drops any object that creates hazard to persons or property.

Free Flight fuses or devices that burn producing smoke and are securely attached to the model aircraft during flight. Rocket motors (using solid propellant) up to a G-series size may be used provided they remain attached to the model during flight. Model rockets may be flown in accordance with the National Model Rocketry Safety Code but may not be launched from model aircraft. Officially designated AMA Air Show Teams (AST) are authorized to use devices and practices as defined within the Team AMA Program Document. (AMA Document #718.)

Not operate a turbine-powered aircraft, unless in compliance with

the AMA turbine regulations. (AMA Document #510-A.) Model aircraft will not be flown in AMA sanctioned events, air shows or model demonstrations unless:

The aircraft, control system and pilot skills have successfully

demonstrated all maneuvers intended or anticipated prior to the

specific event.

An inexperienced pilot is assisted by an experienced pilot. When and where required by rule, helmets must be properly worn and fastened. They must be OSHA, DOT, ANSI, SNELL or NOCSAE approved or comply with comparable standards.

RADIO CONTROL (RC)

All pilots shall avoid flying directly over unprotected people, vessels, vehicles or structures and shall avoid endangerment of life and property of others. A successful radio equipment ground-range check in accordance with manufacturer's recommendations will be completed before the first flight of a new or repaired model aircraft. At all flying sites a safety line(s) must be established in front of which all flying takes place. (AMA Document #706.)

(a)

Only personnel associated with flying the model aircraft are

allowed at or in front of the safety line.

(b)

At air shows or demonstrations, a straight safety line must be

established.

(c)

An area away from the safety line must be maintained for

spectators.

(d)

Intentional flying behind the safety line is prohibited.

Effective January 1, 2015

RC model aircraft must use the radio-control frequencies currently allowed by the Federal Communications Commission (FCC). Only individuals properly licensed by the FCC are authorized to operate equipment on Amateur Band frequencies.

RC model aircraft will not knowingly operate within three (3) miles of any pre-existing flying site without a frequency-management agreement. (AMA Documents #922 and #923)

With the exception of events flown under official AMA Competition Regulations, excluding takeoff and landing, no powered model may be flown outdoors closer than 25 feet to any individual, except for the pilot and the pilot's helper(s) located at the flightline.

Under no circumstances may a pilot or other person touch an outdoor model aircraft in flight while it is still under power, except to divert it from striking an individual.

RC night flying requires a lighting system providing the pilot with a clear view of the model's attitude and orientation at all times. Handheld illumination systems are inadequate for night flying operations.

The pilot of an RC model aircraft shall:

(a)

C. FREE FLIGHT

D. CONTROL LINE

Maintain control during the entire flight, maintaining visual contact without enhancement other than by corrective lenses prescribed for the pilot.

(b)

Fly using the assistance of a camera or First-Person-View (FPV) only in accordance with the procedures outlined in AMA Document #550.

(c)

Fly using the assistance of autopilot or stabilization system only in accordance with the procedures outlined in AMA Document #560

Must be at least 100 feet downwind of spectators and automobile parking when the model aircraft is launched. Launch area must be clear of all individuals except mechanics, officials, and other fliers. An effective device will be used to extinguish any fuse on the model aircraft after the fuse has completed its function.

The complete control system (including the safety thong where applicable) must have an inspection and pull test prior to flying. The pull test will be in accordance with the current Competition Regulations for the applicable model aircraft category. Model aircraft not fitting a specific category shall use those pull-test requirements as indicated for Control Line Precision Aerobatics.

The flying area must be clear of all utility wires or poles and a model aircraft will not be flown closer than 50 feet to any aboveground electric utility lines. The flying area must be clear of all nonessential participants and spectators before the engine is started.

If you are not an AMA member, please consider joining.

Founded in 1936 and open to anyone interested in model

aviation, the AMA is the governing body for model aviation in

the United States and sanctions over 2,000 competitions

anually. Membership in the AMA provides liability insurance

coverage, protects modelers' rights and interests, and is

required to fly at most of the 2,700+ R/C sites nationwide.
