Transmitter Setup
The V-22 Osprey aircraft requires a transmitter with a minimum of six channels
and one open three-position switch.
Flight Modes are selected with channel 5 (GEAR).
Expo: After the first few flights, adjust expo up or down in the transmitter to
better suit your flying style.
Tip: Set the throttle trim at a high idle during flight, and use a throttle cut switch
to shut the motors off. Shutting the motors off on this aircraft will cause the
model to descend rapidly in Multirotor Flight Mode. Keeping the motors turning
at the low throttle point will slow the descent rate when the throttle is reduced.
Refer to your transmitter manual for additional safety information.
This product requires an approved Spektrum™DSM2®/DSMX®compatible
transmitter. Visit www.bindnfly.com for a complete list of approved transmitters.
IMPORTANT: Before binding a transmitter, read the Transmitter Setup section
to ensure that your transmitter is properly programmed for this aircraft.
If you encounter problems, follow the binding instructions and refer to the
transmitter troubleshooting guide for other instructions. If needed, contact the
appropriate Horizon Product Support office.
Transmitter and Receiver Binding
Bind Procedure (BNF)
1. Center all trims and move the throttle stick to the lowest position.
2. Place the aircraft on a level surface. Connect the flight battery to the flight
controller. The motors will produce two tones indicating power. After 10
seconds the orange LED on the receiver will flash indicating it is ready to bind.*
3. Take three steps away from the aircraft/receiver and then put your
transmitter in bind mode. Refer to your transmitter’s manual for specific
binding instructions.
4. The receiver is bound to the transmitter when the LED on the receiver
glows solid orange.
IMPORTANT: The flight controller will not arm the ESCs if the throttle is not
in the lowest position and the throttle trim at or below center.
IMPORTANT: After binding the receiver and transmitter for the first time, the
transmitter must be powered on first, before the aircraft. Failure to power
on the transmitter first will cause the receiver to automatically go into bind
mode and requiring the transmitter and receiver to have to be re-bound.
* The receiver is located inside the fuselage. Remove the bottom hatch to see
the LED on the receiver.

Battery Installation and ESC Arming
Battery Selection
We recommend the E-flite®800mAh 11.1V 3S 30C Li-Po battery
(EFLB8003SJ30). Refer to the Optional Parts list for other recommended
batteries. If using a battery other than those listed, the battery should be within
the range of capacity, dimensions and weight of the E-flite Li-Po battery packs
to fit in the fuselage.
1. Lower the throttle to the lowest settings. Select the multirotor flight mode.
Power on the transmitter and wait approximately five seconds.
2. Carefully lift the front of the battery hatch and pull forward to remove it.
3. Install the fully charged battery in the battery compartment as shown.
Secure using the hook and loop tape.
4. Connect the battery to the flight controller.
5. Keep the aircraft upright, immobile and away from wind or the system may
not initialize.
• The motor nacelles will rotate to the middle position briefly and then to
the upright, Multirotor flight position, indicating the flight controller has
initialized and the ESCs are armed.
CAUTION: Always keep hands away from the propeller. When armed,
the motor will turn the propeller in response to any throttle movement.
6. Reinstall the battery hatch.
7. Refer to the Center of Gravity section to ensure the model balances at the
recommended CG.
Center of Gravity (CG)
The CG location is within 25-30mm,
measured from the the leading edge of
the wing at the root, as shown in the
illustration.
NOTICE: The main motor nacelles must
be in the Airplane Flight Mode when
checking the center of gravity. Failure
to do so will give an incorrect center of
gravity and may cause a crash. Crash
damage is not covered under warranty.

IMPORTANT: The following information refers to the movement of the nacelles
when transitioning from multirotor to airplane mode. While in multirotor mode,
the nacelles may not always be vertical or aligned with each other. This is due
to the way the aircraft uses the nacelle movement to control yaw in multirotor
mode. While in airplane mode however, the nacelles should be aligned with
each other.
If the motor nacelles do not move in unison the aircraft may yaw or roll slightly
when transitioning from multirotor to airplane mode. For example, if the left
nacelle is slightly lagging behind or not traveling far enough when changing
into airplane mode, the aircraft may yaw to the left during the transition. If the
left nacelle is lagging far behind, the aircraft may yaw to the left and roll to the
right during the transition.
Torque Rod Control Arm
Rotation Stop
Nacelle Linkage
BEFORE THE FIRST FLIGHT OF THE AIRCRAFT
Check the nacelle movement to ensure proper alignment. Fully cycle the nacelles
2 or 3 times to ensure they are transitioning evenly. If the nacelles are not
aligned, use the information below to adjust the nacelles before attempting flight.
If the aircraft displays unwanted yaw or roll during the transition from multirotor
to airplane mode, check the nacelle alignment.
Multirotor Mode:
The nacelles may be
at different angles.
Transition to Airplane
Mode: The nacelles may
differ slightly but should be
close to the same angle.
Airplane Mode:
The nacelles should both
be at the same angle, at
or just below horizontal.
IMPORTANT: Always check for proper nacelle alignment with the wing upright.
To check the travel of the nacelles:
1. Power on the transmitter.
2. Enable throttle cut.
3. Power on the aircraft and place it on a flat surface. Wait for the aircraft to initialize.
4. After initialization, with the aircraft upright, cycle the flight mode switch
from multirotor to airplane mode 2-3 times, allowing the nacelles to finish
transitioning each time before switching. Observe the movement of the
nacelles. They should start moving at the same time, remain even through
the full range of travel and stop at both the same time and same angle.
Flight Control Direction Test
This test ensures that the flight control system is functioning properly.
Assemble the aircraft, bind your transmitter to the receiver, and ensure the
aircraft is in Airplane Flight Mode and throttle cut is active before performing
this test. The control surfaces will not respond in Multirotor Flight Mode.
Move the entire aircraft as shown in the table and ensure the control surfaces
respond in the direction as shown. If the control surfaces do not respond as
shown, do not fly the aircraft. Contact Horizon Product Support.
Once the flight control system is active, control surfaces may move rapidly. This
is normal.
CAUTION: Keep all body parts, hair and loose clothing away from a
moving propeller, as these items could become entangled.

39-40mm
Adjusting the Nacelle Alignment
Pushrod Length Adjustment
The pushrods for the nacelle linkages should be 39-40mm long from the clevis
pin to the z-bend. Due to the differences in the splines of the output shafts
of the nacelle servos, the pushrods will not necessarily be identical in length.
Check both linkages to ensure they fall within this range. Turn the clevis in or
out until the length is within this range on both linkages.
Fine Tuning Pushrod Length
Determine if one of the nacelles is not traveling far enough OR one of the
nacelles is traveling too far, overdriving against the rotation stop when in
airplane mode.
IMPORTANT: Always check for proper nacelle alignment with the wing
upright.
If one of the nacelles is not traveling far enough:
shorten the linkage for the nacelle that is lagging behind.
1. Remove the wing.
2. Remove the clevis from the torque rod control arm.
3. Shorten the linkage by turning the clevis in 1/2 turn increments clockwise.
4. Re-connect the clevis to the torque rod control arm.
5. With the wing upright, re-check the movement of the nacelles.
If one of the nacelles is traveling too far, overdriving against the rotation stop:
lengthen the linkage that connects that nacelle rotation servo to the torque rod.
1. Remove the wing.
2. Remove the clevis from the torque rod control arm.
3. Lengthen the linkage by turning the clevis in 1/2 turn increments counter-
clockwise.
4. Re-connect the clevis to the torque rod control arm.
5. With the wing upright, re-check the movement of the nacelles.
With the aircraft upright on a level surface in airplane mode, the nacelles
should be even with each other and level with the surface the plane is sitting
on or pointed slightly down (no more than -2°).
Servo Horn Adjustment
Both servo horns must be at similar angles when in airplane mode for the
aircraft to transition from multirotor to airplane mode correctly.
To check for correct servo horn location:
1. Remove the wing.
2. Disconnect the nacelle linkages.
3. Check the length of the linkages as noted above.
4. Power on the transmitter.
5. Enable throttle cut.
6. Power on the aircraft and place it on a flat surface. Wait for the aircraft to
initialize.
7. Set the flight mode
switch to airplane
mode, allowing the
nacelle servos to fully
transition. Observe the
servo arms from either
wingtip. The horns
should both be at a
similar angle, within a few degrees, similar to the illustration.
8. Manually rotate the nacelles to the airplane mode position until the
rotation stops touch the wing.
9. Attach the linkage z-bends to the servo arms.
10. Attach the linkage clevises to the torque rod control arms. The linkages
should attach to the control arm without having to force them in either
direction. If a pushrod does not fit correctly, remove the corresponding
servo horn and rotate it one spline on the servo output shaft in the
required direction to make the linkage fit easily.
11. With the wing upright, cycle the nacelles to ensure they are tracking
correctly. If after adjusting the servo arm alignment, the nacelles are
not even during the transition to airplane mode or if they do not stop at
the same angle in airplane mode, go to the Fine Tuning Pushrod Length
section to adjust the nacelles.

Linkage Settings and Flight Trimming
The table to the right shows the factory settings for the control horns and
servo arms. Fly the aircraft at factory settings before making any changes to
the control linkages.
Trim
1. With the model sitting on the ground and the motors off, verify the motor
nacelles are positioned level in Airplane Mode with Acro. Make adjustments
to the length of the control linkages between the servo and the torque rod
control horn to make corrections.
IMPORTANT: The nacelles must start and stop moving at the same time and
progress through the full range of movement at the same rate to ensure the
aircraft transitions from multirotor to airplane mode smoothly. If the nacelles do
not move in unison, go to the Fine Tuning Nacelle Alignment section to adjust
their movement.
2. Verify the control surfaces are centered.The trailing edge of the control
surfaces should be centered. With the aircraft in Airplane Flight Mode with Acro
make adjustments to the length of the control linkages between the servo and
control surfaces.
3. Fly the airplane and trim the aileron and elevator controls for level flight in
Airplane Flight Mode and Acro Mode at full power.
4. Land the model and place it on a level surface with the motors off. Switch
into Airplane Mode with Acro then switch from Acro Mode to Stability and
back to Acro to clear the gyro. Keep the model motionless in Airplane Mode
with Acro and note the trim position.
IMPORTANT: The control surfaces will respond to any movement when in
Airplane Flight Mode. The control surfaces will not respond to movement in
Multirotor Flight Mode.
Put the model into Airplane Mode with Acro Flight Mode to center the control
surfaces.
5. Adjust the length of the control linkages to set the control surfaces at the
noted trim positions.
6. Reset the transmitter trims to neutral before flying again.
Understanding the Primary Flight Controls
The V-22 Osprey aircraft has Flight Modes that make it capable of flying forward like an airplane or hovering like a multirotor. It is important to understand how the primary flight
controls function and how the aircraft reacts in both flight modes. Take a few minutes to familiarize yourself with the controls prior to attempting your first flight.

Flying Your Aircraft
Consult local laws and ordinances before choosing a flying location.
Range Check your Radio System
Before you fly, range check the radio system. Refer to your specific transmitter
instruction manual for range test information.
Just Before Flight
Once the flight control system is active, you will normally see the control
surfaces react to aircraft movement.
Prior to your first flight, check the nacelle movement as described in the Fine
Tuning Nacelle Alignment section to ensure proper nacelle alignment.
For your first flights with the recommended battery pack (EFLB8003S30), set
your transmitter timer or a stopwatch to 4 minutes.
NOTICE: Never fly the aircraft without first setting and activating a timer.
After 4 minutes, land the aircraft. Adjust your timer for longer or shorter flights
depending on your preference and battery usage.
Takeoff
Place the aircraft on a flat, level surface with the tail facing you. Set your
transmitter to Multirotor Flight Mode. Ramp up the throttle trim to keep the
propellers turning.
Check that the motor nacelles are in the fully upright position in Multirotor Flight
Mode before applying throttle. Gradually increase the throttle until the model is
approximately 2 ft. (600mm) off the ground. Avoid forcing the aircraft into the air.
It is normal for the aircraft to lift off tail first and move forward as it lifts off.
Multirotor Flight
Try to hold the aircraft in one spot small with small corrections on the
transmitter control sticks. If flying in calm winds, the model should require
almost no corrective inputs, but may steadily move forward. After moving the
aileron/elevator stick and returning it to center the model will level itself. The
model may continue to move due to inertia. Move the stick in the opposite
direction to stop the movement.
After you become comfortable hovering, you can progress into flying the model
to different locations, keeping the tail pointed towards you at all times. You can
also ascend and descend using the throttle stick.
Once you are comfortable with these maneuvers, you can attempt flying with
the tail in different orientations. It is important to keep in mind that the flight
control inputs will rotate with the aircraft, so always try to picture the control
inputs relative to the nose of the aircraft.
NOTICE: Do not attempt to fly backwards at a high rate of speed. While the
aircraft is capable of flying backwards while in Multirotor mode, the aircraft
becomes more unstable as backward speed increases.
Transitioning In Flight
TIP: Always transition between flight modes into the wind.
To transition to Airplane Flight Mode from Multirotor Flight Mode change
the flight mode switch on your transmitter to an Airplane Flight Mode. The
throttle will increase slightly and the motor nacelles will rotate forward to the
airplane flight position. The control surfaces become active. It is normal to have
some slight oscillations in pitch as the aircraft transitions into Airplane Flight
Mode. While in Airplane Flight Mode the main motors use differential thrust to
provide yaw control and the tail motor does not run.
To transition to Multirotor Flight Mode from Airplane Flight Mode reduce
the airspeed, change the switches on your transmitter to select the Multirotor
Flight Mode for landing. The throttle will increase slightly and the motor
nacelles will rotate to the vertical position. The tail motor will power on and
the control surfaces will go to neutral. While in Multirotor Flight Mode the
control surfaces do not move. All pitch, roll and yaw control is accomplished by
differential thrust and angling of the motors.
NOTICE: Do not transition to Multirotor Flight Mode at low throttle or lower
the throttle immediately after transitioning to Multirotor Flight Mode. Doing
so will cause a rapid loss of altitude and possibly a crash.
Airplane Flight
Fly the aircraft and trim it for level flight per the Flight Trimming section.
The V-22 Osprey flies in a similar manner to other fixed-wing aircraft. It is capable
of a wide range of conventional flight maneuvers including loops and rolls.Avoid
negative push maneuvers, the V-22 Osprey is not intended for negative G maneuvers
and may enter an unpredictable spin with hard negative push maneuvers.
Landing
Transition the aircraft into Multirotor Flight Mode and bring it into a low hover.
Slowly lower the throttle to descend to a soft landing.
NOTICE: If a crash is imminent, activate the throttle cut feature. Failure to
do so could result in extra damage to the airframe, as well as damage to the
ESCs, motors and motor nacelles.
NOTICE: Crash damage is not covered under warranty.
NOTICE: When you are finished flying, never leave the aircraft in direct sunlight
or in a hot, enclosed area such as a car. Doing so can damage the aircraft.
Low Voltage Cutoff (LVC)
The average flight time with a mixture of hovering and airplane flight using the
recommended flight battery is approximately 4 minutes.
The flight controller protects the flight battery from over-discharge using
Low Voltage Cutoff (LVC). When the flight battery is drained to LVC the flight
controller will automatically transition the motors into Multirotor Flight Mode.
The remaining battery will last less than a minute, so land the aircraft as soon
as possible.
When the battery reaches LVC in Multirotor Flight Mode the motor power is
sharply reduced for an instant to warn the pilot the model has entered LVC.
In this flight condition the motors will slowly lose power until the ESCs cutoff.
If you notice the motors cut power for a brief moment, land immediately and
re-charge the flight battery.
After landing, disconnect and remove the Li-Po battery from the aircraft to prevent
trickle discharge. Charge your Li-Po battery to approximately half capacity before
storage. During storage, make sure the battery charge does not fall below 3V per
cell. LVC does not prevent the battery from over-discharge during storage.
NOTICE: Repeated flying to LVC may damage the battery.
TIP: Monitor your aircraft battery’s voltage before and after flying by using a
Li-Po Cell Voltage Checker (EFLA111, sold separately).
Repairs
Thanks to the foam material in this aircraft, repairs to the foam can be made
using virtually any adhesive (hot glue, regular CA, epoxy, etc). When parts are
not repairable, see the Replacement Parts List for ordering by item number.
For a listing of all replacement and optional parts, refer to the list at the end
of this manual.
