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 loose 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 Potenza 100A 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.

If you have purchased the Night version of the Cessna 170 60E G2, this page will cover all LED light connections. If you did not purchase the night
version, skip ahead to the next page.
1. There are two connections for each wing panel, one at the leading edge, and one at the trailing edge of the wing. Connect the one at the
trailing edge to the installed JST extension. Route the connector at the leading edge through the hole in the fuselage and plug into the LED
controller directly.
2. If using the floats with lights, connect each JST for the float set to the LED controller in the fuselage. Route the leads through the cooling hole
in the bottom of the fuselage. Secure the wire to the flat strut and fuselage using water proof tape.
LED
CONTROLLER 3S Li-Po
Black/Negative Lead
CONNECTING A BATTERY TO THE LED CONTROLLER
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 Cessna 170 60E G2. Failure to do so can damage your flight
batteries. We recommend the use of thePotenza 3S 2200mAh 45C Li-Po (FPZB22003S45) or 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. Average current draw
for the lighting system is 2.2A/h

11
AURA 8 AFCS
The Aura 8 AFCS (Advanced Flight Control System) comes programmed and pre-installed in your Cessna 170 60E G2, making setup a breeze. This
highly-refined 3-axis gyro makes the Cessna 170 60E G2 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 Cessna 170 60E G2 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 sport flying, test flights or safety.
• Rates and Expos are tuned for sport flying.
• Gyro gain is set to off.
Flight Mode 2: Sport (Gyro On)
• For sport flying.
• Rates and expos are tuned for sport flying.
• 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, the flaps function with the operation of CH6 (Aux 1) on the transmitter.
NOTE - Aileron travel will not change with the flight mode switch. The addition of flaps with the ailerons significantly increases the roll rate,
making the change feel like a low versus high rate.
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 can only be made through the Aura.
The Aura 8 AFCS Profile for the Cessna 170 60E G2 can be changed from the Stock Cessna 170 60E G2 Profile to the Advanced Cessna 170 60E G2
Profile without the need of a computer. For further details, please see the section of this manual titled Optional Advanced Cessna 170 60E G2
Aura Configuration on page 20.
Note: to use the Advanced Cessna 170 60E G2 Profile you will need a 7 channel radio.
LINKAGE SETUP
As you set up your receiver and you Aura 8 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 21 of this manual.
The Cessna 170 60E G2 has ball links on both ends of all control surfaces. If an adjustment is necessary remove the screw assembly on one end,
turn the ball link as necessary and re-attach the screw assembly.
On all control surfaces the ball links attach to the outermost hole on the servo arm and the innermost hole on the control horn as shown below.
NOTICE
The DS34 servos installed in your Cessna 170 60E G2 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.

TRANSMITTER SETUP
The included Aura 8 is designed to work seamlessly with all popular transmitter and receiver brands, however, transmitter setup is significantly
different than when setting up a model without Aura. Follow these steps:
1. Start with a new model memory in your transmitter. Reset it to be certain it is set to defaults.
2. Adjust your transmitter settings according to the Transmitter Configuration Guide below.
3. Make ONLY the changes shown in the Transmitter Configuration Guide. No other changes are required.

Aura will auto-detect modern serial receiver connections. For use in the Cessna 170 60E G2, only a serial receiver connection or a Spektrum
Remote Receiver can be used. Below are a few examples of serial receivers that can be used with the Aura 8. This is not a complete list of
compatible receivers, rather a short list to assist in your receiver selection.
Spektrum Remote Receivers – SPM9745 (2 Required)
Spektrum SRXL – SPMAR6610T, SPMAR8020T, SPMAR10100T
Spektrum SRXL2 – SPM4651T, SPM4650
Futaba S.Bus – Futaba R7008SB, R2001SB, R6202SBW
Hitec S.Bus – Optima SL, Maxima SL
FrSky S.Bus – RX4R, RX6R
Graupner HoTT (Sum D of 8) – GR12L, GR16L
JR XBus (Mode A & Mode B) – RG012BX, RG613BX, RG821BX
Jeti EX-Bus – REX10, R9 EX, REX6
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).

CONNECTING YOUR RECEIVER TO AURA
Note: The Spektrum 4651T
receiver requires the use of a
different cable to connect to
Aura. The cable is included with
the receiver when it is purchased
directly from Flex Innovations.
You can also purchase the cable
itself at flexinnovations.com
(FPZA1039).
Spektrum Remote Receivers
If using two Spektrum Remote Receivers, connect them to
Aura Mini Port A and Mini Port B using the cable provided
with your receivers.
Serial Receivers
If using a standard serial receiver, connect the provided male to male cable to
your receiver’s serial port. Connect the other end of the cable to Aura Port B
noting proper polarity.
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.Bus2 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.

Binding Your Receiver
1. With the transmitter and aircraft powered OFF, place a
bind plug into Aura Port S8.
2. Power on the aircraft. Your remote receiver should flash
rapidly, indicating it is in bind mode.
3. Bind your transmitter to the remote receiver per your
transmitter manufacturer’s instructions. This is typically
done by pressing and holding the bind button on your
Spektrum transmitter while powering it on.
4. Verify the receivers are bound by looking at the LED on
the Remote Receivers. This is typically indicated by a
solid orange LED on Spektrum Remote Receivers.
5. Remove the bind plug from Aura Port S8.
Binding Your Receiver
Bind your receiver to your transmitter per your receiver and transmitter
manufacturer’s instructions.

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 Cessna 170 60E G2.
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

CONTROL DIRECTION TEST
Refer to the chart below to determine the proper control surface responses to transmitter control inputs.
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.

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.

PROP ADAPTER, PROPELLER AND SPINNER INSTALLATION
Required Tools and Fasteners: 2.5mm Hex Driver (3) M3x9 Hex Head Machine Screws
#1 Phillips Screwdriver (1) M3x30 Phillips Head Machine Screw
Adjustable Wrench (1) Prop Washer
Blue Thread Lock (1) Propeller Nut
Note: Do not complete transmitter, receiver and/or Aura setup with the propeller installed.
1. Locate the bolt-on prop adapter for the motor. Apply blue thread lock to each of the three M3x9 hex head machine screws, and secure the prop
adapter to the motor. Make sure that the propeller adapter seats fully against the motor face, and is concentric with the motor shaft.
2. Install the spinner backplate onto the motor shaft. Ensure that it is fully seated.
3. Install the propeller with the convex surface facing forward. The propeller size numbers are printed on the front face of the prop and should
orient forward.
4. Slide the prop washer on the shaft with the widest face aft, and tighten the prop nut.
5. Install the spinner cone, and tighten the M3x30 Phillips Head screw using a #1 Phillips screwdriver. Do not apply blue thread lock and do not
over tighten.

CENTER OF GRAVITY
Setting the center of gravity (CG) is one of the most important steps
for successful flight, particularly with a new airplane. The Cessna 170
60E G2 is an extremely capable airplane with large control surface
throws and a high thrust to weight ratio. These factors make it an
enjoyable aircraft to fly, but if the CG is not within an acceptable
range, it will make the airplane difficult, if not impossible to control.
Prepare the aircraft to its flight-ready state. This means all hardware,
components and flight battery should be installed before
proceeding. The center of gravity (CG) is measured from the trailing
edge of the main wing toward the nose of the aircraft. Lift the
aircraft upright, with all components installed, from the bottom of
the wing at the CG location noted.
The acceptable CG range for the Cessna 170 60E G2 is 83mm to
97mm (3 1/4 inches to 3 3/4 inches). Designer and multi-time world
champion Quique Somenzini has found 90mm ( 3 1/2 inches) to be
the sweet spot in the acceptable CG range based on his extensive
test flights and experience.
NOTICE
The CG measurement should be made with the completed
airframe with all components (batteries, servos, receiver, linkages,
screws, bolts, hardware, etc.) installed. Failure to do so will result in
inaccurate measurement.
BATTERY INSTALLATION
1. Push the spring-loaded battery latch tab back to release the battery hatch. Lift the hatch away from the fuselage, starting at the front.
2. Remove the battery tray by loosening the thumb screw. Slide the tray forward as you gently lift the tray away from the fuselage.
3. Install an adhesive-backed hook strip to the battery tray, and an adhesive-backed loop strip to the battery.
4. Place the battery on the tray, and secure it in place with the hook and loop strap provided.
5. Re-install the tray into the battery compartment by aligning the rear tabs on the tray with the appropriate slots in the fuselage sub-frame.
Once seated in place, secure the tray to the sub-frame using the thumb screw.
6. Reinstall the hatch, and confirm that the latch has positively engaged.
WARNING
When making adjustments to linkages,
transmitter settings, or the Aura 8 flight
control system, remove the propeller to
guard against accidental spool up.
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 severely damaged before the motor will stop

PRE-FLIGHT CHECKLIST
To help ensure a successful first flight, as well as many flights after, perform a few simple pre-flight checks to be sure the aircraft is
ready to fly:
1. Verify the elevators and rudder are properly hinged and in good working order. Pinch a control surface
between your thumb and forefinger and grasp the stabilizers with your other hand. Attempt to move the
control surface back and forth perpendicular to the wing (see Figure 1). Watch the hinges for movement. If you
find any loose hinges, apply a small amount of medium CA to the mounting point, being sure to keep glue
away from the hinge pivot. Wait 15-20 seconds, then apply CA accelerator to cure the CA.
2. Verify the flaps and ailerons are properly hinged and in good working order. Pinch a control surface between
your thumb and fore finger, and grasp 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 re-secure.
3. Verify all control surfaces move freely when disconnected from the servo. If you have a tight or binding
surface, apply a small drop of light oil to each hinge pivot. Move the surface back and forth to work the oil into
the hinge. Repeat as needed..
4. Verify that all hardware and other aircraft parts are properly secured, including those connections that require
blue thread lock. This includes hardware and parts installed by the factory.
5. 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.
6. Verify the C.G. is in the proper location and the battery is secured in place.
7. 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).
8. Verify transmitter stick inputs result in the proper control surface movements (reference page 15) and the Aura
flight modes work properly.
9. Verify aircraft movement results in proper Aura sensor corrections (reference page 16).
10. Verify the motor and ESC function properly. Point the aircraft in a safe direction. Hold the airframe firmly,
smoothly advance the throttle to full and back to idle. Listen and watch for any odd or unusual behavior for
the motor or speed controller.
