SAFETY WARNINGS AND PRECAUTIONS
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 un-flyable. It is your responsibility to ensure the airworthiness of the model.
4. Inspect and check for the correct 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 such 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.
LOW VOLTAGE CUTOFF
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 cutoffis 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 3.0V 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 3.0V per
cell average, and the airplane should be landed immediately.

VERTICAL STABILIZER INSTALLATION
Required Tools and Fasteners: 30-Minute Epoxy #2 Phillips Screwdriver
Craft Sticks (for mixing epoxy) (1) M3x10 Phillips Head Self-Tapping Screw
Mixing Cup
Paper Towels
1. 1. Find the vertical stabilizer assembly. If you have a Night Version, plug the LED strip JST connector into the fuselage JST connector. Power the
LED controller with the balance tab of a 3S Li-Po and verify both the fuselage AND vertical fin LEDs function properly before
proceeding. Reference page 14 for details on how to properly power the LEDs. Contact support before proceeding if you find any LEDs that do
not function properly.
2. Test fit the vertical fin to the fuselage, making sure everything fits properly. Make any adjustments that may be necessary.Use the craft sticks
and mixing cups to mix an adequate amount of 30-minute epoxy. Apply epoxy to the vertical fin as well as the fuselage parts that meet the
vertical fin. Be sure to avoid the LED wiring hole when applying epoxy.
3. Assemble the parts, being sure to wipe up any excess epoxy with a paper towel. Confirm alignment, and wait for the epoxy to cure before
proceeding to the next step. This area of the airplane sees a lot of load so ensure that you use epoxy for this joint for the extra strength it
provides.
4. Temporarily insert the main wing tube and ensure that the vertical stabilizer is perpendicular to the wing tube.
5. Once the epoxy has cured, install the rudder hinge screw using a #2 Phillips screwdriver. Deflect the rudder in both directions by hand to check

AURA 8 AFCS
The Aura 8 AFCS (Advanced Flight Control System) comes programmed and pre-installed in your RV-8 10E, making setup a breeze. This highly-
refined 3-axis gyro makes the RV-8 10E fly like it is a larger aircraft and in less wind. Thanks to the Aura’s advanced implementation, it not only
enhances the flying experience, but it never interferes with the pilot’s control.
The Aura 8 AFCS comes configured with Flight Modes (dual rates, expos and gyro settings) set by the Flex Innovations team, and offers a great
starting point for most pilots. Since these are already configured for you in the Aura, there is no need to set up dual rates, expos or flaps in your
transmitter. Simply follow the Transmitter Configuration Guide in this manual for complete details on the transmitter programming required for
the RV-8 10E and Aura 8 AFCS.
Visit wiki.flexinnovations.com/wiki/Aura for the latest Aura-related product information and updates.
Description of Pre-Loaded Aura Flight Modes
Flight Mode 1: Sport (Gyro Off)
• For general flight, test flights or safety.
• Rates are low and expos tuned for general flight.
• Gyro gain is set to off.
Flight Mode 2: Sport (Gyro On)
• For general flight.
• Rates are low and expos tuned for general flight.
• Gyro is set to low.
Flight Mode 3: Advanced (Gyro On)
• For advanced aerobatic flight.
• Rates are highest and expos are tuned for 3D flight.
• Flaps are coupled with the ailerons for maximum roll rate and authority.
• Gyro is set to moderately high.
In all Flight Modes, Flaps function with the operation of CH6 (Aux 1) from the transmitter.
NOTE - Rudder stick movement will also move the ailerons and elevator. Flap (CH6) movement will also move the elevator. This is NORMAL and
is the pre-programmed mixing..
Each of the modes has been tuned by our team to offer a solid start. Because tastes in control feel are unique, if changes in rate and expo are
needed adjustments should be made through Aura. Changes on gain value may only be made through the Aura.
The Aura 8 AFCS Profile for the RV-8 10E can be changed from the Stock RV-8 10E Profile to the Advanced RV-8 10E Profile without the need of a
computer. For further details, please see the section of this manual titled Optional Advanced RV-8 10E Aura Configuration on page 22.
Note: to use the Advanced RV-8 10E Profile you will need a 7 channel radio.

ESC THROTTLE CALIBRATION
In order to map the full range of the ESC output to your throttle stick motion you will have to preform an ESC throttle calibration. NOTE: Execute
ESC throttle calibration with the propeller and spinner removed.
1. Power on your transmitter, DISABLE any throttle hold or throttle kill switches, completely lower the throttle trim and set the stick to full
throttle.
2. Connect the flight pack to your RV-8 10E.
3. Listen for the tones coming from the ESC through the motor, after about 2 seconds you should hear two tones.
4. Pull your throttle stick back to idle.
5. Listen for the ESC arming tones from the motor.
The ESC throttle range has now been properly calibrated, and is stored in the ESC's memory until it is calibrated again. You can repeat this process
as many times as necessary.
CONNECTING BATTERY/ARMING ESC
Observe the following procedures to safely power up your model
after it has been bound. Ensure propeller is removed unless
this sequence is followed to power up before flight.
1. Turn on the transmitter. Lower the throttle stick AND
throttle trim to their lowest settings. Be sure to wait for your
transmitter to indicate it the radio signal is being broadcast
before proceeding
If a battery is connected to the ESC with the throttle fully
open on the transmitter, the ESC will enter programming
mode. If this occurs, simply disconnect the battery, lower the
throttle and reconnect the battery.
2. Ensure the aileron, elevator and rudder gimbals are centered.
3. 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 initialization process.
4. The ESC will make the motor emit a short, final tone
sequence indicating that the ESC is now armed and that the
motor will spin in response to throttle stick movement.
WARNING
When making adjustments to linkages, transmitter
settings, or the Aura 8 flight control system, remove the
propeller to guard against accidental spool up.
WARNING
Hold aircraft securely when connecting the battery before flight.
Always ensure that the propeller is clear of any and all objects as
they may become entangled.
CAUTION
Always connect the battery when the throttle stick and throttle trim
are in the idle/cut-offposition.
Aura 8 Auto-Detect
Once your receiver is bound, powered, and connected to the Aura, the Aura will begin the Auto-Detect process to learn what type of receiver you
are using and set itself up for that specific system. Auto-Detect is indicated by a series of sweeping LEDs of various colors. After Auto-Detect is
completed, verify that Aura is on and receiving data from your receiver by looking at the LEDs on the Aura.
Ready-To-Fly:
Solid Orange LED: Aura On and Calibrated
Solid Green LED: Aura receiving Valid receiver data
Possible Errors:
Flashing Orange LED: Aura Moved During Power Up
No Green LED: Aura NOT receiving receiver data
CONNECTING YOUR RECEIVER TO AURA (CONTINUED)

LED
CONTROLLER 3S Li-Po
Black/Negative Lead
CONNECTING A BATTERY TO THE LED CONTROLLER (NIGHT VERSION ONLY)
The LEDs on your aircraft 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 left unplugged. If the servo lead of the LED controller is not plugged into the Aura
or a receiver, the LED controller will default in the ON position when powered, allowing the Night Version to be flown at night with a basic
6-channel transmitter or receiver.
IN ORDER TO CONTROL THE LEDS FROM THE TRANSMITTER, YOU MUST USE A STANDARD RECEIVER THAT IS CAPABLE OF 7+ CHANNELS,
AND KEEPS THE SERVO PORTS ACTIVE WHEN USING A DIGITAL DATA STREAM (like S.Bus, SRXL etc.).
WARNING
You MUST use an independent 3S Li-Po battery to power the LEDs in the RV-8 10. Failure to do so can damage your flight batteries.
We recommend the use of the Potenza 3S 500mAh 25C Li-Po (FPZB5003S25).
WARNING
Do not leave the battery plugged into the LED controller for extended periods of time. Doing so can damage the battery.
LINKAGE SETUP
Mechanically adjust the control linkages so that the surfaces are neutral with zero trim and zero sub-trim. Final trim adjustments may be required
during flight. For more information on flight trimming, please refer to the trimming section located on page 23 of this manual.
At the servo, the stock linkage attachment is a Z-bend located in the third hole from the outside in the servo arm for the rudder and the flaps and
the fourth hole from the outside in the servo arm for the elevator and ailerons.
Ball links are used on all control surfaces at the control horn end. The stock attachment for the Elevator and Rudder is located in the outermost
hole, and in the middle hole is used for the for the Ailerons and Flaps.

NOTICE
The DS15 servos installed in your RV-8 10 are high quality, digital servos with metal gear train and ultra-fine gear mesh. This fine
resolution and high tooth count output shaft means that the servo arms pre-installed on the servos may inadvertently 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.

RUDDER AND ELEVATOR LINKAGE INSTALLATION
Required Tools and Fasteners: Elevator and Rudder Pushrod Assemblies #1 Phillips Screwdriver
(4) M2x10 Phillips Head Machine Screw #2 Phillips Screwdriver
(4) M2 Flat Washer Needle-Nosed Pliers (or Hemostats)
(4) M2 Lock Nut 4mm Socket Hex Driver (optional)
(2) M3x6 Phillips Head Machine Screw Blue Thread Lock
1. Locate the rudder and elevator pushrod assemblies, as well as the servo arms and hardware. Note that both pushrods and servo arms are
the same length, but the elevator servo arm will have the linkage installed one hole closer to the servo output shaft.
2. Power on your transmitter, and move your Flight Mode switch (assigned on page 11 of this manual) to Mode 1 (Gyro Off). Power on the
airplane, and confirm the Aura is in Mode 1 by rotating the airplane quickly, and verifying that you get no gyro controlled servo movement.
3. With the aircraft still powered on, install the rudder and elevator servo arms perpendicular to the servo case, being sure to orient the servo
arm towards the bottom of the fuselage. Apply blue thread lock to the M3x6 Phillips head machine screw, and secure the servo arm in place
using a #1 Phillips screwdriver.
4. Use a #1 Phillips screwdriver, M2x10 machine screw, M2 washer and M2 lock nut to secure the linkage to both the control horn and the
servo arm. DO NOT use thread lock, as thread lock can damage the plastic in the nut, as well as the control horn. Use the chart from
the previous page for proper control horn and servo arm linkage locations. Note that the rudder ball link should be placed below the rudder
control horn. The order of components is as follows:
M2x10 Machine Screw
M2 Washer
Servo Arm or Control Horn
M2 Lock Nut
5. Repeat the process for the other control linkage.

MAIN WING INSTALLATION
Required Tools and Fasteners: M3x18 Thumb Machine Screw (2)
1. Remove the canopy from the fuselage by pulling the latch to the rear and lifting the canopy from the fuselage.
2. Insert the main wing tube into the fuselage and roughly center.
3. Slide the left and right wing panels onto the tube. The servos and linkages are mounted on the underside of the wing.
4. Connect the all-in-one servo lead to the receptacle in the wing.
5. If you have a night version, connect the wing JST to the LED controller JST as shown in the picture below.
6. 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.
7. Secure each wing to the fuselage using an M3x18 thumb screw on the inside of the fuselage (you can use a Phillips screwdriver if desired).

CONTROL DIRECTION TEST
Refer to the chart below to determine the proper control surface directions.
If controls are reversed, DO NOT REVERSE CONTROLS IN YOUR TRANSMITTER OR IN THE AURA CONFIG TOOL. Email us at
support@flexinnovations.com for corrective action. Note that BOTH the Transmitter Control Direction Test AND the Flight Controller
Sensor Direction Test MUST BE PASSED! IF EITHER ONE DOES NOT PASS, DO NOT FLY!
NOTE: There is pre-configured rudder to aileron and rudder to elevator mixing programmed into the Aura. Simultaneous
movement of these control surfaces with rudder input is intentional and completely NORMAL.
Additionally: Aura has a built-in flap system that moves the flaps at a slower speed. There is also flap to elevator mixing configured
in the Aura Flap System. This speed and mixing is intentional and completely NORMAL.

AURA SENSOR DIRECTION TEST
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 from the airplane's gyro system, DO NOT FLY THE AIRPLANE, and contact us via email at support@flexinnovations.com
The flight control system activates with RF broadcast. Perform these tests in Mode 3 (higher gain) for better visibility and then in Mode 2, and any
other modes that have gyro gains assigned. (By default, Mode 1 has no gain assigned). Control surface deflections are exaggerated in the
pictures below for clarity. Please note that the control surfaces will move ONLY while the aircraft is being ROTATED.
