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, Inc. 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 the propeller area clear from such items as loose clothing, jewelry, long hair, or tools as they can become entangled.
Keep your hands and body parts away from the propeller 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.
Li-Po 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 ZTW 50A 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 below 3.15V per cell average, and the airplane should be
landed immediately. 4

CONNECTING A BATTERY/ARMING THE ESC
9
1.
2.
3.
4.
Observe the following procedures to safely power up your model
after it has been bound. Ensure propeller is removed unless
sequence is followed to power up before flight.
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.
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 that the motor will spin
in response to throttle stick movement.
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.
WARNING
When making adjustments to linkages,
transmitter settings or the Aura 8 flight control
system, remove the propeller to guard against
accidental spool up.
Hold the aircraft securely when connecting the
battery before flight. Always ensure the propeller
is clear of any and all objects as they may
become entangled.
WARNING
Always connect the battery when the throttle stick
and throttle trim is in the idle/cut-off position.
CAUTION
CONNECTING A BATTERY TO THE LED CONTROLLER (NIGHT VERSION ONLY)
The LEDs on your QQ Extra 300G2 are switchable via the transmitter, and are designed to be powered by 12 volts (3S Li-Po) through the
6S JST-XH balance tab on the LED controller. By default, the LED controller is plugged into Aura Port S7, which uses CH6/AUX1 from the
transmitter for control. Assign CH6/AUX1 in your transmitter to a 2-position switch for control of the LEDs. If the servo lead of the LED
controller is not plugged into the Aura or a receiver, the LEDs will default in the ON position, allowing the QQ Extra 300G2 (Night
Version) to be flown at night with a basic 5-channel transmitter or receiver.
The LEDs should be powered from the flight battery per the diagram below.
LED
CONTROLLER 3-4S Li-Po
WARNING
The LEDs use approximately 1.2A from ONLY 3 cells of the battery powering it. If using a higher cell count battery for power,
3 of the cells will have a lower voltage than the others at the end of each flight. Leave excess voltage in the battery at the
end of each flight to prevent the over-discharging of the cells that power the LEDs. You MUST balance charge your
batteries after each flight the LED controller is powered by anything other than a 3 cell battery.
WARNING
Do not leave the battery plugged into the LED controller for extended periods of time. Doing so can
damage the battery.

Aura will auto-detect modern digital receiver connection(s). Using a
modern digital receiver connection gives the Aura access to
precise data of each channel for additional gyro-enabled outputs,
simplifies wiring, and allows for more advanced features. To
connect a modern digital receiver connection, follow the steps on
pages 10 or 11 (depending on your receiver type), then skip ahead
to page 13.
For traditional PWM receivers without digital connection(s), male to
male servo leads must be used for each channel. Please refer to
the connection diagram on page 12.

Connecting Your Receiver to Aura
1.
2.
3.
4.
5.
Connect one Spektrum Remote Receiver to Mini Port 'A' at the
top of the Aura case. If using two, connect the second to Mini
Port 'B'.
To bind a DSMX Spektrum Remote Receiver connection, insert
a bind plug into Aura Port S8. Port 'B' is NOT for binding.
To bind a DSM2 Spektrum Remote Receiver connection, insert
a bind plug into Aura port S1 AND 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.
Confirm the remote receiver(s) is(are) bound by verifying a solid
LED on the receiver.
Aura will then automatically begin the Auto-Detect process,
indicated by sweeping LEDs on the Aura. Once found, you will
see a solid orange (power and calibrated sensor) and solid
green (valid receiver data) LED on the Aura 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.
Aura will auto-detect these modern digital receiver connections:
Spektrum Remote Receiver(s)
Futaba or Hitec S.Bus
Graupner HOTT (Sum D of 8)
Spektrum SRXL
JR XBus (Mode B)
Jeti UDI12 (standard)*
A PPM (8CH, negative shift, approximately 22ms/frame) receiver may also be
connected into Port 'B', however Aura will not auto-detect and setup must be
performed through the Aura Config Tool (Windows Application).
Spektrum Remote Receivers
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.
If you are using a traditional Spektrum receiver, with
either a digital connection type or with PWM
connections, DO NOT plug any remote receivers into the
Aura 8. They should instead be plugged directly into
your traditional receiver.
10
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 for Spektrum remote receivers.

While Spektrum and Futaba usually output their digital data
stream, it may be necessary for JR DMSS, Graupner HOTT,
and Jeti users to program the transmitter/receiver to output the
correct digital format listed on the previous page. Consult your
transmitter and receiver manuals for further details.
Bind your transmitter and receiver per your manufacturer's
instructions.
Connect the included male to male servo extension to the
receiver's data port (ex: S.Bus, SRXL etc.) and connect to servo
port 'B' on the face of the Aura. Refer to your radio
manufacturer's instructions for specific information on
appropriate serial port connections and system settings.
With the transmitter powered, power up the aircraft. Aura will
search (sweeping LEDs) and lock onto the signal. You will then
see solid orange (power and calibrated sensor) plus solid green
(valid radio source), and have control of the model.

Note: If you are using Futaba S.Bus, be sure to use the proper
S.Bus port in your receiver. DO NOT use the S.Bus 2 port, as it
is not supported for use with the Aura 8. Refer to your
manufacturer's instructions for proper S.Bus use.
Note: When using Spektrum SRXL to connect to the Aura,
always connect the remote receivers to the Spektrum receiver,
NOT to the Aura.
If your receiver has a working throttle port while using it's
digital connection, use it. Move the ESC (throttle) lead from
Aura Port S1 to your receiver's throttle port. Consult your
receiver and/or transmitter instruction manual for specific
details on your system.

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 powerd OFF, connect your receiver to Aura using the diagram below. Note that the throttle is plugged
directly into the receiver. Depending on your particular transmitter, you may need to reverse the throttle in the transmitter when the ESCs
throttle lead is plugged directly into your receiver.
With the propeller removed and ALL connections made (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, a solid orange (aura Running), and solid green (Aura receiving valid signal from the
receiver) LED is illuminated. After the source is found, apply transmitter right rudder to assist Aura to determine your radio type, after
which point control of the model is established. This is only required during initial setup
Connecting a Traditional Receiver to Aura with PWM Servo Connections
12
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. Different from serial data connections
(S.Bus, SRXL etc.) this is how traditional receivers work. In order to utilize this type of receiver connection with your QQ Extra 300G2, male
to male servo leads to connect the corresponding receiver ports to Aura are required. A minimum 5-channel receiver is required to set up
Aura with PWM servo connections. Please purchase FPZAU01 Aura 3-piece male to male servo cable/S.Bus to complete the PWM
connection setup.
NOTICE
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, Gear/CH5 - S4)

Note: The LEDs on the QQ Extra 300G2 Night Version are able to be turned on and off via a channel from your transmitter. For PWM
users, simply plug the servo lead from the LED controller into any open channel on your receiver (such as CH6/AUX1), and assign that
channel to a 2-position switch on your transmitter accordingly.
If you do not have an available channel on your transmitter and/or receiver for the LED controller, you can simply leave the
servo lead unplugged, and the lights will be on by default (once powered). Be sure to secure the wiring to the fuselage.
If you are using a traditional Spektrum receiver, with remote receivers, DO NOT plug any remote receivers into the
Aura 8. They should instead be plugged directly into your traditional receiver.

Insert the horizontal stabilizer tube into the fuselage and roughly center.
Slide the left and right stabilizer halves onto the tube. Ensure that the control horn orients towards the belly of the airplane and that the
elevator joiner tabs are properly indexed. Do not force the stabilizer into place.
Apply four (4) pieces of clear tape to the joint between the stabilizer and the plastic mounts. Be sure to apply tape to both the top and
bottom of each stabilizer.
Attach the clevis to the elevator control horn in the proper hole per the diagram below. Slide the clear tubing over the clevis ends to
secure it in place.

Invert the airplane so that the belly is facing up. Remove the belly hatch by pulling the exposed tab away from the fuselage.
Install the wing tube into the fuselage.
Slide the left or right wing panel on the wing tube and guide the servo wire and LED wire (night version only) into the fuselage.
Secure the wing to the fuselage with one (1) M3x15 self-tapping screw. Push the wing tube completely into the wing until it stops. Do
not force it into place.
Slide the other wing panel on the wing tube and guide the servo wire into the fuselage. Seat the wing to the fuselage completely, but do
not force it into place.
Plug the left aileron servo wire into the S2 port of the Aura, and the right aileron servo wire into the S3 port of Aura. Connect the LED
wires directly to the LED controller.

Occasionally there may be some flashing left inside the wing tube support rings inside the wing panels. This flashing may prevent the
wing tube from seating fully into the wing. You can remove this flashing with a hobby knife or a dowel wrapped with some 300 grit
sand paper. Do NOT shorten the wing tube, as it relies on this outer ring for structural support.

If you have a night version, remove the backing from the adhesive strip on the exposed LEDs in the wing tip. Place both LED strips on
the side of the SFG that faces the fuselage, along the long edge of the SFG. One should be placed above the wing, and the other
should be placed below the wing. NOTE: The plastic skid on the SFG should be oriented toward the ground with the aircraft upright.
Liberally apply medium CA to the airfoil-shaped mounting tab on the inside of the SFG.
Insert the SFG into the molded cavity in the wingtip and press tightly. NOTE: The plastic skid on the SFG should be oriented toward the
ground with the aircraft upright.

Pull the spring loaded latch away from the nose, and lift the rear of the hatch off the fuselage.
Install adhesived-backed hook and loop tape to both the battery and the battery tray.
Place the battery in the battery tray and secure it with the provided hook and loop strap. Use the image below to reference the location
of the recommended battery.
Re-install the hatch, and confirm the latch has positively engaged.
CAUTION
Always keep limbs clear from the propeller when the battery is connected. After the ESC arms, the propeller will rotate when the throttle
is moved. Unlike an internal combustion engine, electric motors apply more voltage to counteract resistance, therefore any object that
is entangled in the propeller will be severly damaged before the motor will stop.
WARNING
When making adjustments to linkages, transmitter settings, or the Aura 8 Flight Control System, remove the propeller to
guard against accidental spool up.

Perform a test of the gyro system to verify the corrections made for a given movement are correct. If any of the tests do not result in the
correct reaction for the airplane's gyro system, DO NOT FLY THE AIRPLANE, and contact us by email at [email protected] or
by phone at [phone].
The flight control system activates with RF broadcast. Perform these tests in Mode 3 (higher gain) for better visibility, and then again in
Mode 2, and any other flight modes that have gyro gains assigned. (By default, Mode 1 has no gain assigned.) Control surface deflections
are exaggerated in the drawings below for clarity. Please note that the control surfaces will move ONLY while the aircraft is ROTATING.
