INTRODUCTION
The Cessna 170 and the Aura 8: the perfect combinaon!
The Cessna 170 is the evoluon and accumulaon of many years of
experience in the aerodynamic and electronic stabilizaon world. A perfectly
tuned airframe design, combined with today's most advanced control system
gives an unmatched ying experience.
Pilots will feel smooth, precise aircra control without any interference to
pilot inputs. The aircra will y as if it were much larger, turbulent air will be
less noceable, rotaons will stop more precisely and landing will be easier
to execute. Flex Innovaons has tuned and matched both to their best
potenal, however, the Aura 8 programming capability allows total freedom
to the pilot to adjust (including seng ight modes that can turn it o). USB
rmware update capability allows you to enjoy and benet from the latest
features and advancements.

IMPORTANT INFORMATION REGARDING WARRANTY
SAFETY WARNINGS AND PRECAUTIONS
Please read our Warranty and Liability Limitaons secon 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
condion to the place of purchase.
LOW VOLTAGE CUTOFF
Protect yourself and others by following these basic safety guidelines.
1. This manual contains instrucons for safety, operaon and maintenance. It is essenal to read and follow all the instrucons 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 sophiscated hobby product and must be operated with cauon 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 instrucons. Do not alter or modify the model outside of these instrucons
provided by Flex Innovaons, Inc. as doing so may render it unsafe and/or unyable. It is your responsibility to ensure the airworthiness
of the model.
4. Inspect and check operaon of the model and all its components before every ight.
5. If you are not an experienced pilot or have not own a high-performance model before, it is recommended that you seek assistance
from an experienced pilot in your R/C club for your rst ights. If you're not a member of a club, the Academy of Model Aeronaucs
(AMA) has informaon 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 y 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 intermient failures.
LiPo baeries have a nominal (rated) voltage of 3.7V per cell, and fully charged, reach 4.2V per cell. Baeries 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 baery life, set a mer and land aer a me that leaves approximately 15% of the baery's capacity
remaining.
Low voltage cuto is a feature that is built into the Hobby Wing SkyWalker 80A ESC that is designed to protect the connected baery
from being discharged too far and causing permanent damage to the cells. Circuitry within the ESC will automacally detect when the
input voltage from the baery pack reaches below 3.15V per cell (average) and will remove power to the motor, but sll deliver power
to the servos so that a safe landing may be made. If the motor begins to lose power rapidly during ight, 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.

NIGHT CESSNA LED CONNECTIONS
LED Controller
Two Wing Connecons
Float Connecon
If you have purchased the Night version of the Cessna, this page will cover all LED light connecons. If you did not purchase the night version, skip
ahead to the next page.
In order to power the internal Night LED lights (not wing p or landing lights) you will need to use a seperate 3S Lithium-Polymer baery. We
recommend the Potenza 3S 2200mAh 40C Li-Po (FPZB22003S40). Average current draw for the lighng system is 2.2A/h.
There are two connecons for each wing panel, one at the leading edge, and one at the trailing edge of the wing. Connect the one at the
1.
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.
If using the oats with lights, connect each JST for the oat set to the LED controller in the fuselage. Route the leads through the cooling hole
2.
in the boom of the fuselage. Secure the wire to the at strut and fuselage using water proof tape.
The fuselage LED strip is pre-connected to the LED controller for you. Should it become disconnected, connect it to one of the four JST
3.
connectors on the LED controller.
Connect the balance tab (JST-XH) of any 3-Cell (12V DC) Li-Po baery (greater than 1300mAh, and 20C) to the balance tab adapter on the LED
4.
controller. When connected, the lights are automacally powered. Turn to the LED lights o, disconnect the baery from the LED controller.
The LED controller defaults to a non-ashing mode. It has dierent ashing modes, and dierent ashing speeds available. Simply select the
5.
speed or mode by pressing the buon(s) on the LED controller unl a desired seng is reached.

WARNING
CONNECTING BATTERY/ARMING ESC
Observe the following procedures to safely power up your model aer
it has been bound. Ensure propeller is removed unless sequence is
followed to power up before ight.
1.
2.
3.
4.
Lower the throle sck and trim to their lowest seng and turn
on the transmier. Wait for your transmier to indicate the RF
signal is being broadcast before proceeding.
If a baery is connected to the ESC with the throle fully open
on the acve transmier, the ESC will enter into programming
mode. If this occurs, simply disconnect the baery, lower the
throle, and reconnect the baery.
Ensure the rudder, elevator and aileron scks are centered.
With the airplane on a solid surface, connect the baery to the
ESC and wait. The ESC will emit a series of audible tones during its
inializaon process.
The ESC will emit a short, nal tone sequence indicang that the
ESC is now armed, and that the motor will spin in response to
throle sck movement.
When making adjustments to linkages, transmier sengs, or the
Aura 8 ight control system, REMOVE THE PROPELLER to guard
against accidental spool up.
WARNING
DO NOT ATTEMPT RADIO SETUP WITH PROPELLER INSTALLED. INADVERTENT POWER UP COULD CAUSE PERSONAL INJURY.
TRANSMITTER SETUP
Begin by starng with a freshly reset and new model memory in your transmier. Make ONLY the changes shown in the Transmier Setup Guide.
The Aura 8 on the Cessna 170 defaults to 3 ight modes that are switched via CH5/Gear in your transmier. You may need to reassign CH5/Gear to
a 3-posion switch. Consult your radio manual for direcons on channel assignment.

Note: Rudder sck movement will also move ailerons and elevator.
This funconality is NORMAL.
Each of the modes has been tuned by our team to oer 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 8.
Changes in gain value can only be made via Master Gain, or through
the Aura Cong Tool (Windows Applicaon).
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 transmier,
and tune through the Aura Cong Tool.

RECEIVER INSTALLATION/SERVO CONNECTIONS
Aura will Auto-Detect modern data-linked receivers. The advantage of using a modern data-linked receiver is the ability to have 4 addional gyro-enabled
outputs to servos (total of 8 outputs), as well as wiring simplicity versus tradional PWM connecon types. To connect a modern data-linked receiver,
follow the steps on this page, then skip ahead to page 14.
For tradional PWM receivers (male to male servo leads for each channel), refer to the connecon diagram on page 13.
Supported Modern Data-Linked Receivers
Aura will Auto-Detect these modern data-linked receivers:
Spektrum Remote Receivers (2 required for the Cessna)
Spektrum SRXL
Futaba S.Bus
JR XBus, Mode B
Graupner HOTT, Sum D of 8*
Je UDI12* (Standard)
You can also use a PPM (8ch, Negave, Approximately 22ms Frame) connecon in Port B, but it
will not auto-detect, and will need to be set in the Aura Cong Tool (Windows Applicaon)
Connecng Your Receiver to Aura
Spektrum Remote Receivers
Connect (2) Spektrum Remote Receivers to Mini Port 'A' and Mini Port 'B' at
1.
the top of the Aura case.
To bind a DSMX Spektrum Remote Receiver connecon, insert a bind plug into
2.
Aura Port S8.
To bind a DSM2 Spektrum Remote Receiver connecon, insert a bind plug into
Aura port S1 AND S8.
Power up the model, and the remote receivers should begin to ash, indicang
they are ready to bind. Bind from here as recommended in your transmier
manufacturer's instrucons.
Once bound (indicated by each remote receiver showing a solid orange LED),
3.
Aura will begin the Auto-Detect process, searching for a valid control signal,
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,
indicang the Aura is in its ight-ready state.
Mount your receivers using double sided foam tape, or hook and loop tape.
4.
Consult your receiver manual for proper mounng orientaons.
All Other Data-Linked Receivers
For JR DMSS, Graupner Ho and Je, consult your radio documentaon and

RECEIVER INSTALLATION/SERVO CONNECTIONS (CONTINUED)
PWM Connecons
If you are using a digital receiver connecon, and have completed the steps on page 12, skip ahead to the next page.
PWM is an acronym that stands for Pulse Width Modulaon. PWM is how tradional receivers send a signal to the servo to command the servo
move to a parcular posion. In short, PWM in regards to the Cessna requires the use of male to male servo extensions to connect each channel
from your receiver, to each port in the Aura. Due to the aps and the ight modes in the Aura, a minimum of a 6-channel receiver and transmier is
required to maximize the funconality of the Cessna 170. A 7+ channel receiver and transmier is recommended.
Depending on your parcular radio and PWM setup, some addional items to purchase are required:
FPZAU01
FPZA1011
FPZA1012
1.
Bind your receiver to your transmier by following the instrucons included with your radio and/or receiver. Verify it is bound by connecng a
spare servo to your receiver, and that it responds to transmier inputs.
2.
With the transmier and receiver powered OFF, connect your receiver to the Aura using the diagram below. Note the throle AND both aps are
plugged directly into the receiver. Important: all four (4) PWM male-to-male leads must be properly connected for the Aura to acvate servo
outputs!
3.
With the propeller removed and ALL connecons made between the Aura and the receiver (and in the proper polarity), power on your
transmier, and power on the airplane with the ight baery, and keep the airplane staonary. Aer a few seconds, the LEDs on the Aura will
sweep back and forth as the Aura searches for a valid control signal. Once found, you will see a solid orange (Aura running) and solid green (Aura
is receiving a valid signal from the receiver) LED. Aer the source is found, apply transmier right rudder to assist Aura in determining your
radio type, then you will have control of the model.

hatch is o of the fuselage.
3.
Press the baery to the center of the baery tray and secure with the provided hook and loop straps. Depending on your baery selecon,
locaon may vary. Consult the center of gravity secon at the boom of this page in order to set the baery locaon for the proper center of
gravity.
4.
Reinstall the hatch in reverse order, and conrm that the latch has posively engaged.
5.
Always keep limbs clear from the propeller when the
baery is connected. Aer the ESC arms, the propeller
will rotate when the throle is moved. Unlike an
internal combuson 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.
CENTER OF GRAVITY
The locaon of the center of gravity (CG) for the Cessna
170 is 90mm (3-1/2-inches) AFT of the leading edge of
the wing at the wing root, plus or minus 7mm (1/4-inch).
This measurement was determined from many test
ights by designer and many me world aerobac
champion, Quique Somenzini. Li the airplane from the
underside of the wing to check the CG. Be sure to keep
the model level while measuring CG (model should be in
its ying posion, where the boom of the airfoil is
level).
Seng the center of gravity is one of the most important
steps for success, parcularly with a new airplane. The
Cessna is a versale airplane, with many dierent baery
opons, large throws, and a high thrust to weight rao.
These factors make it a very enjoyable aircra to y, but
if the center of gravity is not within an acceptable range,
it will make the airplane dicult, if not impossible, to
control.
When making adjustments to linkages, transmier
sengs, or the Aura 8 ight control system, remove

FLYING YOUR CESSNA 170
Takeo
Taxi or place the aircra on the runway centerline, with the nose
pointed into the wind. Select Flight Mode 2, with the aps in the up
posion for the rst ight. Set throle trim so that the motor spins
at it's lowest RPM without stopping. Smoothly advance the throle
to full while maintaining direconal control with the rudder and
slight back pressure on the elevator. The airplane should li o
smoothly before the throle is fully open. Fly in Flight Mode 2 unl
the aircra is fully trimmed (see special trimming instrucons), and
you are comfortable with it's handling, then explore the other
modes as desired.
Flying
Altude is your friend on the rst ight. Briskly climb to a safe
altude and trim the airplane. The airplane should y straight and
level at 2/3 power (depending on baery pack voltage selecon),
with no input from the scks. Try some basic maneuvers, and slowly
progress into the airplane's ight envelope as you become more
comfortable with the airplane's ight qualies and perfect your
setup. Note: if at any me, such as aer gain adjustments, you
experience unexpected control system inputs or oscillaons, switch
to Mode 1, and land and troubleshoot the issue. (Mode 1 turns the
sensor inputs o with default programming)
Trimming
The rst several ights on your Cessna 170 should be dedicated to
trimming and setup. Fly the airplane at 2/3 power in Flight Mode 2
and trim for level ight. Land, adjust linkages and return the trim to
zero, and y again. Repeat unl the airplane ies hands o, straight
and level. Transmier trim or sub-trim will cause trim shis when
dierent ight modes are selected. To eliminate this trim shi, you
can mechanically trim the model, or you can complete and Aura
"Quick Trim".
Aura Quick Trim
The Aura 8 features a Quick Trim Mode that eliminates the need
for mechanical linkage adjustments during test ights. Aura will
learn the trim values from your transmier, and apply them to the
control surfaces at power up when enabling quick trim mode.

Landing
Be mindful of your ight me and allow adequate baery reserve
for a couple of landing aempts, if necessary, on the rst few
ights. For the rst few landings, land with the aps in the up
posion. Select Flight Mode 2 and slow the airplane and align with
the runway, into the wind. The airplane should descend smoothly
in this conguraon with proper airspeed. Once you are close to
the ground, gradually close the throle 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.
NOTE:
Quick Trim can also be used BEFORE ying to make
small changes to center the control surfaces before
ight.
Fly the airplane in Flight Mode 2. Trim the aircra with the
transmier and land. DO NOT CHANGE FLIGHT MODES.
Power o the Aura. Insert a bind plug into Aura Port S3 (you
will need to remove the servo lead that is currently in S3).
Check the transmier is on and repower the Aura.
Wait 5 seconds for the Aura to completely inialize. Conrm

ash quickly aer control surface trim values are store. While
the trim values are stored in Aura, they are not applied to the
control surface(s) unl the Aura is repowered.
Remove power from the Aura and center all control surface
trims on the transmier.
Repower the Aura. The control surfaces should be unchanged
even though the trim has been centered on the Transmier.
Switch between other Flight Modes to ensure you do not see
any changes in trim.

NOTE:
Selecng a Flying Site
Selecng a ying site is crical to a successful ight. Airplanes
require a lot more room than other R/C products, therefore, a
neighborhood or parking lot is not recommended. A local AMA eld
is the best locaon for ying your Cessna 170. If no AMA eld is
available in your area, a large open eld with short grass and
generous overy area is the best candidate. Know your overy area.
Ensure that there are no houses, playgrounds, people or other
buildings that may be damaged if the airplane were to crash.

LEARNING TO USE FLAPS WITH THE CESSNA 170
The Cessna 170 was designed from the ground up to be the most
versale and fun-ying aircra possible. Pilot workload has been
greatly reduced thanks to its nely tuned aerodynamic design, and
the pre-set conguraon of the Aura 8 Advanced Flight Control
System. Pilots of all skill levels will quickly nd the Cessna 170 is a
forgiving airplane, in many dierent atudes and ight regimes.
Sharpening Your Skills & Understanding How Flaps Work
Obviously, before aempng to y with aps, you should be procient at
ying an airplane, and be comfortable ying the Cessna 170 in various
atudes.
As a short aerodyamics explanaon, aps essenally change the airfoil or
cross-secon shape of the wing, and have two primary goals or funcons
depending on the model. One, to add li (by changing the airfoil shape)
and two, to increase drag. A high-li airfoil is typically at boom, or
undercambered (boom wing prole curves in similar direcon to the
top prole). By adding ap deecon, the wing transforms into a parally
undercambered airfoil, generang more li, and more drag as a byproduct. Due to this addion of li, variances in airspeed can cause pitch
changes in the aircra when the aps are deployed. Typically with a high
wing model like the Cessna 170, the addion of ap input will cause a
pitching-up moment, as the model is not "trimmed" for that amount of
li at that parcular speed. To combat this, many experienced pilots will
use "ight mode trims" that change elevator trim with ap posion, or a
ap to elevator mix, so that this pitching up moment is automacally
compensated for. Note that it is virtually impossible to eliminate this
pitching moment at all airspeeds, but can be compensated for in the
most common airspeeds the pilot will use the aps. Quique's ap to
elevator mixing recommendaons are in the chart to the right for your
reference.
It is important to understand that this pitching moment when the aps
are deployed is normal. It is also normal for this pitching moment to vary,
depending on airspeed.

First Flights with Flaps
For rst ights, it is recommended to have two ap posions, a half
ap seng, and a full ap seng. It is also helpful to have the ap
speed slowed to about 1.5 seconds. As with learning anything new,
altude is your friend. Start at a safe altude, several mistakes high,
and begin to slow the model down. It is best if you move the
throle to the o or idle posion, and let the airplane stabilize in a
slight descent. Once the model has stabilized at a slow airspeed
and slow decent, move the ap switch to the half ap posion.
Note that the model may pitch up slightly, but quickly will stabilize
into a shallow descent again. Once the aircra has stabilized in the
half ap posion, move the ap switch to the full posion, nong
that the model may pitch up once again. Full ap, depending on
airspeed, may require a small amount of down elevator pressure to
keep it from pitching up. Note that the higher the airspeed, the
more the model will pitch up when aps are applied. It is always
best to deploy the aps at slower airspeeds unl you are
comfortable with how the model acts when the aps are deployed.
As you become more comfortable with the aps, you'll soon realize
how much they aid in short-eld takeos and landings!
My Cessna Rolls When I Deploy Flaps!
This is typically caused by ap travels that are not traveling the
same amount. This can be xed by adjusng ap linkage length,
and/or servo arm posion on the spline of the servo. Consult our
Cessna wiki page for more detailed informaon:
hp://wiki.exinnovaons.com/wiki/Cessna170
ADVANCED "3D" CESSNA SETUP
The Cessna comes with addional ap pushrods that are longer than the stock (installed) pushrods. This allows the aps to travel in both the up and down
posion, much like ailerons. With this capability, you can mix the aps with the ailerons and have much greater aileron authority in slow speed "high-alpha"
ight, and also mix in "crow" or speed brake funconality as well. Also, the aps are in the roll axis gyro loop, which allows them to correct along with the
ailerons for changes in roll. This adds extra stability at slow speeds, including landing, and 3D ight.
Should you choose to install these pushrods, you will need to re-program the Aura 8. A new Aura Cong le pre-programmed for this advanced setup is
located on the Aura Wiki page. To install, download the Aura 8 Cong Tool, and download the Advanced Cessna Setup. Follow the direcons on the wiki
page to program the Aura 8 with this cong le. Both the cong le, and Aura Cong Tool can be found here:
hp://wiki.exinnovaons.com/wiki/Cessna170
It is important to note that this advanced setup is not compable with PWM Aura connecon types. If you sll want similar capability with a PWM setup,
mixing in your transmier is required. Consult your transmier manufacturer or manufacturer's manual for further assistance.

AIRFRAME REPAIRS
The Cessna 170 is molded from durable EPO foam and is repairable with most adhesives. Similar to building and repairing wood or composite
airplanes, the correct glue for a given applicaon is crical to the repair holding and not breaking again. For major repairs, such as a broken
fuselage, epoxy is preferred because it allows me to correct any misalignment. For smaller repairs, such as a cracked control surface or small chunk
of material missing from the airframe, regular CA is very eecve. The use of oderless (foam safe) CA is not recommended on EPO foam aircra
because it is weaker than regular CA and takes a longer period of me to cure and the bond tends to be weaker.
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
