BATTERY CHARGING GUIDELINES
The assembly of the QQ Cap 232EX can be accomplished i
n
less than one hour. Prior to assembling the airplane, it is
advisable to charge your battery so that you are ready to begin
setup upon completion of the assembly of your model.
We recommend the use of an advanced Li-Po balancing
charger, such as our Potenza C80 Multi Chemistry Touch
Screen AC/DC balancing charger for your batteries to get the
maximum performance and lifespan.
Our airplanes are designed around our Potenza Li-Po batteries,
and we recommend the Potenza 6S 3500mAh 40C Li-Po for
advanced aerobatics, or the Potenza 5S 5200mAh 40C Li-Po
for sport aerobatics based on our extensive testing and
development. These batteries feature an EC5 connector, so no
soldering is required for use in your QQ Cap 232 EX.

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 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. 4

The rudder comes pre-hinged to a small section of vertical fin. Test fit the rudder and fin section onto the fuselage and remove it
from the fuselage once fit is confirmed.
Lay the fuselage on its side, and using medium CA or epoxy (foam-safe is not required), apply an adequate amount to the
fuselage. Press the rudder and vertical fin section into the fuselage, being sure to wipe away any excess glue.
Secure the lower plastic hinge in place by threading an M3x10 phillips washer head self-tapping screw through the bottom of the
plastic hinge in the fuselage. Do not fully tighten, as you can cause the rudder to bind. A small amount of play is needed here.
Allow time for the CA to dry, and once dry, check for proper rudder movement. Be sure the rudder moves freely with little to no
binding.
Press the tailwheel wire into the plate on the bottom of the rudder. Be sure to orient the tailwheel such that it angles aft as it moves
away from the fuselage. Lay the tailwheel plate over the wire, and secure it in place with three M3x10 phillips head self-tapping
screws.

MAIN LANDING GEAR INSTALLATION
Required Tools and Fasteners:
Locate the landing gear, axle assemblies, wheel pants, and M4 nuts and washers.
Use a Phillips screwdriver to remove the M3x12 self-tapping screws from the wheel pants, and separate the wheel pant halves from
one another.
Remove the M4 nut and washer from the axle assembly (if required). Slide the axle through the landing gear, and place an M4 washer
over the exposed threads of the axle. Secure the axle in place using an M4 lock nut, and two 7mm wrenches. Tighten fully.
Install the inside-half of the wheel pant to the landing gear using an M3x10 Phillips head machine screw, and blue thread lock. If you
wish to leave the wheel pants off of the aircraft, you can skip this step as well as step 5.
Re-install the outside half of the wheel pant to the inner half using the M3x12 self-tapping screws removed in step 2.

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
this page, then skip ahead to page 11.
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 10.
Note: When using S.Bus, Aura reverses the throttle direction. It
is therefore NOT necessary for Futaba S.Bus users to reverse
the throttle IF the throttle/ESC is left plugged into the Aura.

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
bind plug into Aura Port S8.
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.
Once bound (indicated by each remote receiver showing a solid
orange LED), Aura will begin the Auto-Detect process, indicated by
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.
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 above. 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 extension to the receiver's data
port (ex: S.Bus) 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.
Mount your receiver using double sided foam tape or hook and loop
tape. Consult your receiver manual for proper mounting and
antenna placement.
Aura will auto-detect these modern digital receiver connections:
Spektrum Remote Receivers
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.
Note: If you are using Futaba S.Bus be sure to us the S.Bus
port in your receiver. Do NOT use the S.Bus 2 port, as it is not
currently supported for use with the Aura 8.
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.

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 brand, 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
10
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 QQ Cap 232EX, male to male servo leads to connect the corresponding receiver ports to Aura are required. A
minumum 6-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 Cap 232EX 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.

CONNECTING A BATTERY/ARMING THE ESC

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 Cap 232EX 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 S6, 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 Cap 232EX (Night
Version) to be flown at night with a basic 5-channel transmitter or receiver. The LEDs can be powered in two ways:
1.
2.
You can use a separate 3S Li-Po, by plugging the battery's balance connector directly into the balance connector on the LED controller.
Plug the battery balance tab into the LED connector so that the ground or black wire on your battery is fully to one side of the LED
controller's connector. Be sure that the tab nearest the black wire on your battery aligns with the slot in the LED controller's connector.
You can plug your flight battery's balance tab directly into the connector on the LED Controller. If using a 5S battery, be sure to align the
tab nearest the black wire on your battery with the slot in the LED controller's connector (reference the image below for 5S Li-Po).
LED
CONTROLLER
3-5S Li-Po
6S-Li-Po
WARNING
The LEDs use approximately 3.5Ah 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.

LINKAGE AND HORIZONTAL STABILIZER INSTALLATION
12
Required Tools and Fasteners:
Locate the rudder and elevator pushrod assemblies. Note that both pushrods and servo arms are the same length, but they are
connected to different locations in the servo arms. Reference the servo arm chart at the bottom of the page for more details.
Power on your transmitter, and move your Gear (CH5) switch to Mode 1 (Gyro Off). Power on the airplane, and confirm the Aura is in
Mode 1 by moving the airplane quickly, and verifying that you get no gyro controlled servo movement.
Install the servo arm perpendicular to the servo case, being sure to orient the servo arm torwards the bottom of the fuselage. Apply blue
thread lock to the M3x6 phillips head machine screw, and secure the servo arm in place. Verify that the M2x10 phillips head machine
screw and M2 lock nut that attaches the ball link to the servo arm is secure.
Insert the horizontal stabilizer tube into the fuselage, and roughly center.
Slide the left and right sides of the horizontal stabilizer onto the tube. Ensure the control horn orients to the bottom of the fuselage, and
that the elevator joiner tabs are indexed properly. Do not force the stabilizer into place.
Apply 4 pieces of clear tape to the joint between the stabiizer and the plastic mounts. Be sure to apply tape to both the top and bottom
of the stabilizer halves.

NOTICE
The DS-33HV servos installed in your QQ Cap 232EX are high quality, digital servos with all metal gear train and fine
gear mesh. This fine resolution and high tooth count output shaft means that the servo arms pre-installed on the servos
may inadvertantly be misaligned, yet appear properly installed. It is critical to ensure the positive, perpendicular
orientation of the arm to the case to ensure that the travel of the servos is even from side to side at extreme throws. If the
arms are not installed properly, remove and realign as needed. Be sure to use blue thread lock on the servo arm screw.

MAIN WING AND SFG INSTALLATION
14
Required Tools and Fasteners:
Remove the canopy from the fuselage by pulling the latch to the rear of the canopy and lifting the canopy from the fuselage. Insert the
main wing tube into the fuselage and roughly center.
Slide the left and right wing panels onto the tube. Ensure the servos orient to the bottom of the fuselage.
Connect the aileron servo leads to their respective extensions in the fuselage. If you have a night version, connect the wing JST to the
fuselage JST connector.
Fully seat the wing into the fuselage while being careful to align the wing mounting tab with the slot in the fuselage. Be sure to avoid
pinching any wires during this process. Secure the wing to the fuselage using a phillips screwdriver and an M3x10 washer head screw.
Place the SFGs on the wing tips, and secure them in place using a phillips screwdriver and two M5x35 nylon phillips head screws. Do
not overtighten.

Pull the spring loaded latch away from the nose, and lift the front of the canopy 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 6S 3500mAh 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.

CENTER OF GRAVITY VERIFICATION
19
The center of gravity (CG) location for the QQ Cap 232EX is located
4-1/8 inches (105mm) AFT of the rear-most side of the landing
gear slot and is measured by lifting the completed airplane upright,
with all components installed. This location was determined from
many test flights by designer and multi-time world aerobatic
champion, Quique Somenzini. Lift the airplane from the underside
of the wing to check CG.
Setting the center of gravity is one of the most important steps for
success, particularly with a new airplane. The QQ Cap 232 EX is a
high-performance airplane with large control surface throws, and a
high thrust-to-weight ratio. These two factors combined make 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.
NOTICE
The CG measurement should be made with the completed
airframe with all components (batteries, servos, receiver,
linkages, hardware, etc.) installed. Failure to do so will result
in an inaccurate measurement.

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. If hinging is loose, do not fly. Apply thin CA to the loose side(s) of the hinge(s) to resecure.
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 15).
Verify aircraft movement results in proper Aura sensor corrections (reference page 16).
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 propeller. 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 od or unusual behavior from the motor and ESC.
