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 included 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.
Note: The ESC is set to low timing for efficiency.

Description of Pre-Loaded Aura Flight Modes (FM)
Mode 1 (Gyro Off):
Gyro gain is set to 0 (off). All rates are set to low for general flight (same as Sport Mode). Exponential is tuned for comfortable flight.
Mode 2 (Sport):
Gyro gains are moderate and tuned for comfortable feel/best performance for general flight. All rates are set to low for general flight.
Exponential is tuned for comfortable flight.
Mode 3 (High Rate/Live Wing Mode):
Gyro gains are moderate and tuned for general flight. Flaps work with aileron in roll. All rates are set to highest. Exponential is tuned for
comfortable flight.
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 rates and
expo are needed, adjustments should be made through the Aura.
Changes in gain value can only be made through the Aura.

WARNING
DO NOT ATTEMPT RADIO SETUP WITH PROPELLER INSTALLED. INADVERTENT POWER UP COULD CAUSE
DEATH OR SERIOUS INJURY.
TRANSMITTER SETUP
The Aura 8 AFCS is designed to work seamlessly with all major transmitter and receiver brands. When programming your transmitter, start
with a freshly reset new model memory in your transmitter. Make ONLY the changes shown in the Transmitter Configuration Guide
unless otherwise noted.
The Aura 8 in your aircraft defaults to 3 flight modes that are switched via CH5/Gear in your transmitter. You may need to reassign CH5/
Gear to a 3-position switch.
The Night LEDs are switchable on/off via the transmitter. You will need to use a standard receiver, and plug the LED controller into an open
channel port in your receiver. You may need to reassign that channel in your transmitter 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 designed for your aircraft. 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 download, and can be used on any Windows-based PC or tablet. Download at:

CONNECTING A BATTERY/ARMING THE ESC
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
CAUTION
WARNING
WARNING
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.
1.
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.
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 intialization process.
4.
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.
Always connect the battery when the throttle stick
and throttle trim is in the idle/cut-off position.
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.
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.).
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 Night Version to be flown at night with a basic 6-channel transmitter or receiver.
The LEDs should be powered from a separate 3S Li-Po battery per the diagram below.
The LEDs draw approximately 2.5A 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.
Do not leave the battery plugged into the LED controller for extended periods of time. Doing so can
damage the battery.

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.
2.
Bind your transmitter and receiver per your manufacturer's
instructions.
3.
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.
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.
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.
4.
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: When using Spektrum SRXL to connect to the Aura,
always connect the remote receivers to the Spektrum receiver,
NOT to the Aura.

RECEIVER INSTALLATION/SERVO CONNECTIONS (CONTINUED)
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. 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 aircraft, male to male
servo leads to connect the corresponding receiver ports to Aura are required. A minimum 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.
1.
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.
2.
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, and other connections will need to removed per the diagram below. 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.
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
3.
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
to Aura inputs for Aura to activate servo outputs. (Aileron - S1, Elevator - S2, Rudder - S3, Gear/CH5 - S4)

CENTER OF GRAVITY VERIFICATION
AEROBATIC
10-13/16 in.
(275mm)
OR
The center of gravity (CG) location for your aircraft is located in two
locations depending on the flying style you wish to fly.
For general sport flying, the CG is located 11-7/32 inches
(285mm) FORWARD of the trailing edge of the wing.
For more aerobatic capability, the CG is located 10-13/16
inches (275mm) FORWARD of the trailing edge of the wing.
These CGs are 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 RV-8 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.

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
1.
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, including those connections that require blue thread lock. This
2.
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

Verify aircraft movement results in proper Aura sensor corrections (reference page 21).
7.
Verify the motor and ESC function properly. Point the aircraft in a safe direction, and away from any objects or limbs that could become

FLYING YOUR RV-8
Takeoff
Taxi or place the aircraft on the runway centerline, with the nose
pointed into the wind. Select Flight Mode 2, then set throttle trim so
that the motor spins at it's lowest RPM without stopping. For the
first flight, set flaps to up. Smoothly advance the throttle to full while
maintaining directional control with the rudder and slight back
pressure on the elevator. The airplane should lift off smoothly
before the throttle is fully open. Fly in Flight Mode 2 until the aircraft
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 airplane 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 airplane'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, and land and troubleshoot the issue. (Mode 1
turns the sensor inputs off with default programming)
Trimming
The first several flights on your aircraft 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 the trim t
CAUTION
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 aircraft. 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.
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 slow the airplane and
align with the runway, into the wind. Keep the throttle at 1/8-1/4
power for the majority of the decent. The airplane should
descend smoothly in this configuration with proper airspeed.
Once you are close to the ground, gradually close the throttle
fully and begin to smoothly apply up elevator as required to
arrest descent and the airplane should gently touch down with
a short roll out. 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. After you get comfortable landing the aircraft without
flaps, you can experiment more with both flap positions on
landings.
zero, and fly again. Repeat until the airplane flies hands off, straight
and level. Transmitter trim or sub-trim will cause trim shifts when
different flight modes are selected. To eliminate this trim shift, you
can mechanically trim the model, or you can complete Aura "Quick
Trim".
Please note, due to the nature of Aura Flight Modes, trim in low
rates will not be as effective as trim in high rates. This functionality
is NORMAL.
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 at power up when enabling quick trim mode.

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 stored.
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 should be
unchanged 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.

AIRFRAME REPAIRS
NOTICE
Your aircraft 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 and takes a longer period of time to cure.
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
mindful of the locations of CA to prevent premature bonding of parts or bonding a hand or clamp to the airframe.
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.
If a crash is imminent, fully reduce the throttle to prevent further damage to the power system and reduce energy to lessen
impact damage. Never allow the propeller to contact the ground under power, even at a slow idle.
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.
REPLACING SERVOS
Required Tools and Fasteners:
1.
Disconnect the servo from the Aura 8.
2.
Unscrew the servo arm screw from the servo, and remove the servo arm.
3.
Unscrew the two servo mounting screws at each end of the servo and remove. Please note, the aileron servo extensions are wired to
the navigation lights for connection simplicity. DO NOT remove the aileron servo extensions from the wing, as damage to your
navigation and landing lights may occur.
#1 Phillips Screwdriver
TIP: Plug a spare servo extension into the servo lead before removing to make it easier to install the lead of the servo when replaced. Note
that this dones not work for the aileron servo extensions, as they should not be removed per step 3 above.

Academy of Model Aeronautics National Model Aircraft Safety Code
A.
GENERAL: A model aircraft is a non-human-carrying aircraft
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.

B.
1.
2.
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.
