INTRODUCTION
Biplanes oer a unique challenge as every aspect of the design must be
optimized, from the structure, to the aerodynamics, and control system.
Only years of experience designing aircraft in this category can produce
the Mamba 10's aggressive, yet forgiving characteristics. Designer Quique
Somenzini knows how to optimize biplane aerodynamics like no other,
having won F3A and 3D world championships with his biplane designs. A
biplane with less coupling or better manners cannot be found. The
structure is highly optimized oering an aircraft that is sti and strong,
yet light in weight.
Couple a phenomenal airframe with the Aura 8 Advanced Flight Control
System, the latest in stabilization technology, and you get an incredible
performance package; one that remains stable, yet maneuverable. Pilots
rave about its direct and non-interfering feeling, and its ability to bring
out the best in aircraft.

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, 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 operation 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 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 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 intermittent failures.
LOW VOLTAGE CUTOFF
LiPo 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 cuto is a feature that is built into the Hobby Wing SkyWalker 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 3.15v 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 ight, 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.

TRANSMITTER SETUP
TRANSMITTER CONFIGURATION GUIDE
Start with a freshly reset new model memory in your transmitter.
Make ONLY the changes shown in the Transmitter Setup Guide.
The Aura 8 in the Mamba 10 defaults to 3 ight modes that are
switched via CH5/Gear in your transmitter. You may need to
reassign CH5/Gear to a 3-position switch. Consult your transmitter
manufacturer for directions on channel assignment.
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 Cong Tool.
The Aura Cong Tool can be used on any Windows-based PC or
tablet. Download at www.exinnovations.com/AuraCongTool.

The Aura 8 advanced ight control system installed in your Mamba 10
is a giant leap forward in aircraft ight control system technology.
Compatible with virtually every receiver on the market today, the
Aura features special conguration for DSM systems via remote
receiver connection(s), and serial data connection for Futaba S.Bus,
Spektrum SRXL Graupner HOTT (Sum D of 8), JR XBus (Mode B), and
Jeti UDI12 (standard) systems, as well as being compatible with
traditional receivers via PWM servo connections.
The Aura 8 advanced ight control system in your Mamba 10 has been
pre-tuned for ease of use, eliminating many hours of tedious setup.
For the latest Aura Features, programs, transmitter downloads, and
instructions, please visit wiki.exinnovations.com/wiki/Aura.
The Aura is fully customizable through any Windows-based PC or
tablet. All dual rate, expo, travel, and assignable mode programs are
adjusted inside the Aura through the PC application. An assignable
master gain that is OFF by default can be enabled by the Aura
application. If desired, assign CH 8/AUX 3 on a proportional dial or
slider.
By default CH5/Gear is used to select the 3 ight modes by 3
position transmitter switch.
Description of Pre-Loaded Aura Flight Modes
Mode 1 (Gyro O): Rates are set for general ight (same as
Sport Mode). Exponential is tuned for comfortable ight.
Mode 2 (Sport Mode): Gains are moderate and tuned for
comfortable feel/best performance for precision aerobatics.
Expo is tuned for comfortable ight.
Mode 3 (3D Mode): Gains are highest and tuned for 3D
aerobatics. Rate are set to highest. Exponential is tuned for
comfortable ight.
NOTE- Rudder stick movement will also move ailerons and
elevator. This is NORMAL and is the pre-programmed mixing.
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 rate
and expo are needed adjustments should be made through Aura.
Changes on gain value may only be made through the Aura.

RECEIVER INSTALLATION/SERVO CONNECTIONS
Aura will auto-detect modern digital receiver connection. Using a
modern digital receiver connection gives the Aura access to precise
data of each channel for additional gyro enabled outputs, simplies
wiring, and allows for more advanced features. To connect a modern
digital receiver connection, follow the steps on this page, then skip
ahead to the control direction test on page 12.
For traditional PWM receivers without digital connection, male to
male servo leads must be used for each channel. Please refer to the
connection diagram on page 9.
Supported Modern Digital Receiver Connections
Aura will detect these modern digital receiver connections:
Spektrum Remote Receiver(s) Spektrum SRXL
Futaba S.Bus JR XBus (Mode B)
Graupner HOTT (Sum D of 8) 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 Cong Tool (Windows Application)
Connecting Your Receiver to Aura
Spektrum Remote Receivers
1. Connect (1) Spektrum remote receiver to Mini Port ‘A’ at the top
of the Aura case.
2. 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.
If you are unsure which type of DSM remote receiver
you have, start by attempting the bind process with the
bind plug in S8. If you continue to have trouble
binding, then insert a bind plug into S1 AND S8
Connect the ight battery to the ESC, and the remote receivers
should begin to ash, indicating they are ready to bind. Bind from
here as recommended in your transmitter manufacturer's direction.
3. Once bound (indicated by each remote receiver showing a solid
orange LED), 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, indicating the
Aura is in its ight-ready state.
4. Mount your receivers using double sided foam tape, or hook and
loop tape. Consult your receiver manual for proper mounting
orientations.
All Other Digital Receiver Connections
1. While Spektrum and Futaba typically output their digital data
stream, it may be necessary for JR DMSS, Graupner HoTT and Jeti
users consult your radio documentation and program the
transmitter/receiver to output the correct digital data format as
listed above.
2. Bind your transmitter and receiver per your manufacturer's
instructions.
3. 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 specic
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.
4. Mount your receiver using double sided foam tape or hook and
loop tape. Consult your receiver manual for proper mounting and
antenna placement.

Graupner users, for more information, please visit
NOTE: It may be necessary to move the ESC lead to another
open port (such as port ‘B’)during the binding
procedure. 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 a Spektrum remote receiver.
NOTE: When using S.Bus, Aura reverses throttle direction. It is therefore NOT necessary for Futaba S.Bus users to reverse throttle IF the
throttle/ESC is left plugged into Aura.
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 specic angle in a specic 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 Mamba 10, male to male servo leads to connect the corresponding receiver ports to Aura are required. A minimum 6-channel receiver
is required to setup Aura with PWM 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 powered OFF, connect your receiver to Aura using the diagram below. Note that the throttle is plugged
directly into the 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 to Aura inputs for Aura to activate servo outputs. (Aileron - S1, Elevator - S2, Rudder - S3, Gear/CH5 - S4)
3. With the propeller removed and ALL connections made between Aura and the receiver (observing correct polarity), power on your transmitter and the airplane with the ight 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 determine
your radio type, after which point control of the model is established. This is only required during initial setup.

CONNECTING BATTERY/ARMING ESC
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 ight.
1. Lower the throttle stick and trim to their lowest setting
and turn on the transmitter. Wait for your transmitter to
indicate the RF 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 into
programming mode. If this occurs, simply disconnect the
battery, lower the throttle, and reconnect the battery.

NOTICE
The DS15 servos installed in your Mamba 10 are high quality, digital servos with all metal gear train and ultra-ne gear mesh. This
ne 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, particularly on the rudder servo.
1. Insert the prop collet onto the motor shaft. Ensure that it is fully seated.
2. Temporarily remove the prop nut and washer and 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.
3. Slide the prop washer on the collet with the widest face aft, and tighten the prop nut.
NOTICE
Spin the motor over by hand to ensure that the spinner is true after installation.

BATTERY INSTALLATION
1. Push the spring-loaded battery latch tab back to release the battery hatch.
2. Press the battery to the battery tray and secure with the provided hook-and-loop strap. With the recommended battery, the front edge
align with the front edge of the battery hatch.
3. Reinstall the hatch, and conrm that 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 severely damaged
before the motor will stop
CENTER OF GRAVITY
The location of the center of gravity for the Mamba
10 is located 2 9/16-IN (65MM)AFT of the
LEADING EDGE of the BOTTOM WING and is
measured by lifting the completed airplane upright,
with all components installed, by the bottom wing.
This measurement was determined from many test
ights by designer and many time world aerobatic
champion, Quique Somenzini. Lift the airplane from
the underside of the wing to check the CG.
Setting the center of gravity is one of the most
important steps for success, particulary with a new
airplane. The Mamba 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 y, but if the center of
gravity is not within an acceptable range, it will make
the airplane dicult, if not impossible, to control.
WARNING
When making adjustments to linkages, transmitter
settings, or the Aura 8 ight control system, remove
the propeller to guard against accidental spool up.
2 9/16-IN (65MM)
15
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.

FLYING YOUR MAMBA 10
Selecting a Flying Site
Selecting a ying site is critical to a successful ight. Airplanes
require a lot more room than other R/C products, therefore, a
neighborhood or parking lot is less than ideal. A large open eld
with short grass and generous overy area are the best candidates
if no AMA eld is available in your area. Know your overy area ensure that there are no houses, playgrounds, or other buildings
that may be damaged if the airplane were to crash.
Takeo
Taxi or place the aircraft on the runway centerline, with the nose
into the wind. Select Mode 2, then set throttle trim such that the
motor spins over smoothly at its lowest RPM without stopping.
Smoothly advance to full throttle while maintaining directional
control with the rudder and slight back pressure on the elevator.
The airplane should lift o gently before the throttle is fully open.
Fly in Mode 2 until the aircraft is fully trimmed (see special
trimming instructions), and you are comfortable with its handling,
then explore the other modes as desired.
Flying
Altitude is your friend on the rst ight. Briskly climb to a safe
altitude and trim the airplane out. The airplane should y straight
and level a 1/2 to 3/4 power with no hands on the transmitter. Try
some basic maneuvers, and slowly progress into the airplane’s
ight envelope as you become more comfortable with the
airplane’s ight 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 o with default programming)
Landing
Be mindful of your ight time and allow adequate battery reserve
for a couple of go-arounds, if necessary, on the rst few ights.
Select Mode 2 and slow the airplane and align with the runway,
into the wind. The airplane should descend smoothly in this
conguration 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.
CAUTION
USE CAUTION WHEN FLYING YOUR MAMBA 10 IN MODE 3
AT HIGH AIRSPEEDS. DOING SO CAN INDUCE CONTROL
SURFACE OSCILLATIONS AND MAY CAUSE A CRASH.
Trimming
The rst several ights on your new Mamba 10 should be
dedicated to trimming and setup. Fly the airplane at 2/3 power
in Mode 2 and trim for level ight. Land, adjust linkages
and return the trim and/or subtrim to zero and y again.
Repeat process until the airplane ies hands o, straight
and level.
Transmitter trim or sub-trim will cause trim shifts when
dierent ight modes are selected. To eliminate this trim shift,
the model should be mechanically trimmed, or Aura “Quick
Trim” may be used instead.
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 transmitter, and apply them to the
control surfaces at power up when enabling quick trim mode.
NOTE: Quick Trim can also be used BEFORE ying to make small
changes to center the control surfaces before ight.
1. Fly the airplane in Flight Mode 2. Trim the aircraft with the
transmitter and land. DO NOT CHANGE FLIGHT MODES.
2. Power o the Mamba. Insert a bind plug into Aura Port S3 (you
will need to remove the servo lead that is currently in S3).
Check the transmitter is on and repower the Aura.
3. Wait 5 seconds for the Aura to completely initialize. Conrm
Quick Trim mode is active by checking the Blue LED is slowly
ashing.
4. 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
ash 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.
5. Remove power from the Mamba and center all control surface
trims on the transmitter.
6. Repower the Mamba. The control surfaces should be unchanged
even though the trim has been centered on the transmitter.
7. Switch between other Flight Modes to ensure you do not see
any changes in trim.
NOTE: QUICK TRIM MAY BE REPEATED AS NEEDED FOR
FINE TUNING, OR IF CHANGES TO THE AIRCRAFT
ARE MADE.
NOTE: ENSURE AILERON/ELEVATOR/RUDDER SUB-TRIMS ARE ZERO BEFORE FLYING FOR
QUICK TRIM PROCESS
NOTE: QUICK TRIM IS NOT AVAILABLE TO PWM CONNECTION USERS. IF YOU ARE USING A PWM
CONNECTION TYPE, YOU WILL NEED TO MECHANICALLY TRIM THE MODEL

ADVANCED MAMBA 10 SETUP
The design characteristics of a biplane lend themselves well to advanced aerobatic setup with some congurations and maneuvers that are
simply not possible with a monoplane. While the Mamba 10 is optimized in every way to ensure maximum performance in the stock
conguration, presented here are several pre-congured upgrades for the advanced yer that will help elevate the performance and
enjoyment of the Mamba 10 to the next level!
Optional 4S Motor Setup
For yers wanting more power or dierent ying style, we have developed a plug-and-play 4S power system solution for the Mamba 10
utilizing a custom-modied 1070Kv version of the Potenza 10 motor installed in the stock Mamba 10. In the interest of convenience and
simplicity, the existing 50A ESC and propeller are used in the upgraded power system, only the motor and battery are dierent.
NOTE: The APC 12x4.5MR propeller is also a great
choice with this 4S motor and battery combination.
CAUTION
Required Parts and Accessories: FPZM1010D Potenza 10 1070Kv Motor
FPZB22004S40 4S 2200mAh 40C LiPo Battery
Required Tools: #1 Phillips Screwdriver, #2 Phillips Screwdriver, 13mm Box Wrench
1. Use a #2 Phillips screwdriver to remove the spinner cone and a 13mm box wrench to loosen the prop nut. Remove the entire propeller
and collet assembly from the motor and set it aside as they will be reused.
2. Use a #1 Phillips screwdriver to remove the motor mounting screws from the rewall. Place the screws aside as they will be reused.
3. Unplug the stock motor from the ESC, noting the color of the wires. Match the color of the wires of the 4S motor when reconnecting.
4. Using the screws removed in step 2, attach the motor back to the rewall with a #1 Phillips screwdriver. Ensure screws are tight.
5. Reinstall the prop collet and spinner.
DO NOT ATTEMPT TO USE A 4S BATTERY
WITH THE STOCK 1400KV 3S MOTOR!
Advanced Mamba 10 Aura 8 Conguration
Expert Flight Modes
The Aura 8 installed in the Mamba 10 is equipped with two possible Aura Congurations — Stock and Expert. These may be accessed
WITHOUT THE USE OF A WINDOWS-BASED PC OR TABLET by using the Aura Quick Set feature. The “Expert” version oers three ight
modes: High Speed 3D, Sport, and Slow Speed 3D.
NOTICE
The "Expert" ight modes cannot be congured by Quick Set when using PWM Servo Connections to Aura.
Flight Mode 1 - High Speed 3D
For high speed ying (full throttle) at
high rate. Ideal for tumbling and
high energy aerobatics.
Rate for aileron is 70% while rudder and
elevator travelling at max deection.
Gain are set low and expo are set high.
For information on how to access and setup Aura Quick set,
visit http://wiki.exinnovations.com/wiki/Mamba10/QuickSet.
Crow
The Mamba 10 is the only PNP 3D foam biplane on the market in this size with four individual aileron servos instead of two servos with
interconnect linkages. This exibilty, usually only found in larger biplanes, allows the Mamba 10 to take advantage of several key aileron
setups, primarily the “world famous QQ biplane crow”. Crow is used to slowing downlines and helping make amazing short-eld landings
and is accomplished by simultaneously raising both upper ailerons and lowering both bottom ailerons to increase drag.
In the past, this has required a very advanced transmitter with complex programming , but with the Aura 8, it is as simple as creating and
uploading a new Aura Cong File before heading to the ying eld - no hours of setup and trimming with a complex, expensive transmitter
required!
Visit http://wiki.exinnovations.com/wiki/Mamba10/Crow for instructions how to easily create the Crow conguration in the Aura Cong
Tool and adjust the Aura Servo connections. Please note that a windows-based PC or tablet will be required to upload this le to the Aura 8.
Rates are low, expo adjusted for smooth ight.
Flight Mode 2 - Sport
For sport or precision aerobatics.
Gains are set low.
Flight Mode 3 - Slow Speed 3D
Ideal for harriers, torque rolls, hovering,
waterfalls, at spins, etc.
Rate in all control surface at max.
Gains are set high.
Note: This mode should not be used to y
the airplane at high speed. Control
surface oscillation might occur if
the airplane is own at high speed
in this mode.

AIRFRAME REPAIRS
The Mamba 10 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 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. For smaller repairs, such as a cracked control surface
or small chunk of material missing from the airframe, regular CA is very eective. The use of odorless (foam safe) CA is not recommended on
EPO foam aircraft because it is weaker than regular CA and takes a longer period of time 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 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 the front of the manual for a complete listing of spare airframe parts.
NOTICE: 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 idle.
BE ADVISED THAT CRASH DAMAGE IS NOT COVERED UNDER ANY PRODUCT WARRANTY.
Avoid keeping the airplane in direct sunlight when not ying. Excessive heat can damage the airplane’s structure and UV
damage can permanently discolor decals.
REPLACING AILERON SERVOS
Required Tools and Fasteners: #1 Phillips Screwdriver, #11 or single-edged razor blade
1. Unplug the servo from the receiver.
2. Unscrew the servo arm from the servo and remove the servo arm.
3. Using a sharp blade, carefully cut the tape around the perimeter of the servo. DO NOT CUT THE SERVO LEAD.
4. Unscrew the two mounting screws located at each end of the servo and remove.
TIP: Plug a spare extension lead into the servo when removing to make it easier to install the lead of the
servo when replaced.

2. Remove the (4) bolts holding the motor to the rewall using a #1 Phillips screwdriver. Disconnect the motor from the ESC.
3. To remove the ESC, simply unplug its lead from the receiver or Aura and the output leads from the motor.
OPTIONAL WHEEL PANT REMOVAL
For yers that want the lightest possible setup, or that y o of rough/unimproved elds, the wheelpants on the Mamba 10 are designed
to be removable. Two wheel collars have been provided in the hardware bag to retain the wheels after the wheelpants are removed.
1. Invert the airplane and locate the two wheelpant retaining screws and remove them. Slide the wheelpants and tires o of the axles.
2. Remove the wheel from the wheelpant and reinstall on the axle.
3. Slide the wheel collar onto the axle with the shoulder (oset) side towards the wheel. Tighten the set screw on the wheel collar.
