1: Safety Notices
This product is not a toy. Improper operation may cause bodily injury or property damage. It is
highly suggested for beginners new to this hobby to seek help from an experienced RC pilot.
1.1 Please follow all lithium-polymer battery safety procedures and warnings. If you are new to
using Li-Po batteries, be sure to research their specific handling. Do not puncture the
battery. Do not store the battery fully charged as it will lose its capacity overtime and
discharge. Do not overcharge or over discharge the battery. Keep the battery away from
flammable materials. Do not charge the lithium polymer battery unattended. Monitoring the
Li-Po charge and checking the charge process is highly suggested. Remember, Lithium
Polymer batteries should not get warm during the charging process. If the battery becomes
warm or hot during charging, please disconnect the battery from the charger immediately.
Consult with the dealer for more information if needed.
1.2 To avoid injury and damage, do not operate this model in a crowded space, in the presence
of high voltage cables, and keep away from buildings. Be sure to follow local, state-wide or
country-wide rules and regulations.
This model and its electronic components are not suitable for flying in rainy or windy
weather. Avoid flying when wind speed reaches 6 MPH or higher.
1.3 To avoid damage or bodily harm, the propeller must be undamaged and fastened. Do not
attempt to repair broken propellers.
1.4 Make sure to use fully charged or brand new AA batteries in the transmitter/remote control
to prevent signal loss. If you are using your own transmitter system, please be sure to fully
charge your transmitter if applicable.
1.5 To begin operation, the transmitter must be turned on first with the throttle stick set to its
lowest possible position. Next, the V-22 MUST BE on a flat surface. Plug in the battery to
the V-22 and allow at least 5 seconds for the Flight Control Board unit to initialize before
picking up the V-22 and taking flight. After flight, always turn off the model first by
unplugging the battery before turning off the transmitter.

4: Assembly and Pre-Flight Check
This model arrives partially assembled. The fuselage has been mostly assembled and tested at
the factory, but additional assembly is required for the tail section.
4.1 You will require glue such as foam-safe epoxy to attach the vertical and horizontal stabilizers
to the fuselage. Epoxy or CAglue(Foam-safe) is suggested. Make sure to center the
two vertical stabilizers parallel to the centerline of the fuselage, as shown on the images
below. Always test fit the vertical stabilizers and horizontal stabilizer to insure proper
fitment before applying adhesive. Remove any paint on the surface where glue will be
applied for a stronger adhesion. TIP: You can use packing tape, clear scotch tape to
remove the paint from areas where glue will be applied. Simply press the tape on the
areas and peel the tape off. Most time the paint will peel away with the tape.

4.2 Install the main wing onto the fuselage using the included (3) PB2.5X35 self-tapping screws
as shown below.
4.3 Proceed to setting up your connections by opening the cabin as shown.
4.4 In this step, you will connect all the required servo wires to the receiver and join the Left
Motor (LM) and Right Motor (RM) leads from the Flight Control Board (hereafter referred to
as FCB) unit.
The FCB will have the wires from the model pre-connected, leaving only those for the
receiver and the motors (match RM to RM and LM to LM). Your Banana Hobby V-22 wires
should be labeled with tab names on the wires for proper configuration. Be sure to identify
them all correctly.
Afterwards, you will be ready to connect the servo leads from the FCB to your receiver as
shown in the next page. Pay particular attention to polarity (matching wire colors) and
sequence (proper channel). The FCB shows “- + s” for polarity matching. Black or brown is
“-“, red is “+” and white or orange is “s”.

4.5 Install the landing gears as shown below. NOTE:Landing gear is pressure fitted. If you
decide to use them, simply press the landing gears into their respective slots.
4.6 Install the Elevator pushrod included with your V-22. NOTE: There may be a larger
mounting slot for the pushrod on the servo arm and control horn. Use these pushrod slots
for best performance. The pushrod end with the control clevis is to be used on the elevator
side and the Z wire bent side is to be used on the servo arm side.
4.7 We recommend checking all push rods and control surfaces to make sure they are
operating in the correct configuration before flight.
4.8 Before installing the propeller blades, separate the 3 clockwise blades and the 3 counter
clockwise blades. The Left Motor uses CLOCKWISE rotation blades. The Right Motor uses
COUNTER CLOCKWISE rotation blades. Install the propellers as shown below with (3)
PM2.5X6 screws.
NOTE: You will receive 2 fiberglass discs for propeller installation (Not shown in the photos
below). Please install 1 disc per motor side on TOP of the propeller blades. Only then,
install the PM2.5X6 Screws. TIP: Do not over-tighten the propeller blades! Each blade is
to be tightened only to where it feels a small amount of friction when moved with your hand.
For safety and flight performance reasons, DO NOT OVERTIGHTEN!

5: Function Check
Standard pre-flight checks, make sure to follow these procedures:
5.1 Check if the propeller has been installed properly.
5.2 Lower throttle settings (right stick for Mode 1 or left stick for Mode 2) and then power on
your transmitter.
5.3 To power on the plane, (1) lift open the canopy, (2) plug battery to the electric speed
controller, (3) allow the model to initialize on a flat surface and place battery in its designated
location to achieve a balanced center of gravity (see center of gravity check).
WARNING AND PRE-CAUTION:
a. To prevent bodily harm, you may choose to skip the propeller installation (step 4.7)
before bench-testing the motors. These propeller blades spin at very high RPMs and
may cause injuries. Do not to bench-test the motors or taxi the airplane for longer than
half a minute. This is to prevent overheating of the electric speed controllers due to the
lack of ventilating air that is otherwise present in flight.
b. When testing the surface controls, beware of the direction they are moving in. If the
surfaces are reversed, shut off the model to adjust. To correct this, double check the
Servo Reversing switches on the transmitter for the following channels: aileron (1),
elevator (2) and rudder (4).
c. To prevent the receiver from bouncing around in the fuselage during flight, affix the
receiver inside the fuselage with double-sided tape.
5.4 When the transmitter has been turned on and the battery is connected to the V-22, the
receiver and stabilization board will initiate. At this time, do not move any transmitter
surface controls or the model.Allow up to 30-60seconds for the V-22FCB unit to
initialize. You can visibly see initializing confirmation when the nacelles rotate and stop.
Always Power ON with the Nacelles in the VTOL position.
5.5 Check allservo arms to be sure they are not get tangled with any wires. Ifthe arms become
tangled during flight, it may cause the model to lose control and result in a crash.Always
secure wires away from servo arms and pushrods.
5.6 Channel 5 will be responsible for changing between horizontal and vertical flight. Please
check the motor nacelle position is correct or according to the following photo guide. Ifnot
correct, please adjust the linkage rods from the 17g servo. Correction method: please use
M3 hexagon wrench to loosen the screws on the rotating armshown in the photo (Thread
Lock has been used on these M3 Screws. If needed, use a solder iron tip while the iron is
HOT and press against the M3 screw. This will soften the Thread Lock and be able to
remove. If the M3 Screw is forced, it may strip the 1.5mm HEX Head. Now move the motor
nacelle to correct position and re-lock the rotating arm. Note: Ifyou are using your own
computer transmitter system, you may skip the mechanical step by centering with your
transmitter's sub-trim, and End Point function menus. Before flight, be sure all the four
screws on the rotating arm arefastened tightly.

VTOL Mode
NOTICE: Motor Nacelles will move forward and backward in VTOL mode.
Standard Flight – Airplane Mode
Internal FCB Unit is still active for stabilization.
5.7 When applying throttle, the left and right propellers will rotate as shown in the photo below.
If the direction is incorrect, please turn everything off and switch two of the three wires
between the ESC and motor. On your first hover, stay low to the runway or grass to confirm
all controls are correct. You may use sub-trim to achieve level hover and forward flight.
Rotation direction is as shown in the following photo (Right and Left is from the pilot’s
cockpit point of view).
NOTICE: The aileron servo travel is smaller in VTOL mode because of the FCB stabilizer limit,
but the travel will become standard when switched to airplane mode. 7

9
5.8 Double check the nacelle rotation by using the CH. 5 function. Be sure the Nacelle's
achieve proper rotation levels.
5.9 Check channels 1, 2 and 4 for proper response. Be sure the control surfaces are neutral
when not in use. Remember, make sure the surfaces are not reversed!
5.10 Double check the entire fuselage assembly as well as the tail section prior to flight.
NOTICE: Trim Setup: When hovering in VTOL flight, the model can be adjusted by using the
trim tabs. This can be used when there is forward/backward or side by side drifting.
NOTICE: Winds can affect stability when in VTOL mode because of the model’s
characteristics. If to be flown in LIGHT wind conditions, stability increases when the nose is
against the wind or flying forward. Please consider do not allow the model have a severe tail
wind or to fly backwards in a quick manner. This may result in stability/vibrating issues and
lead to a loss of altitude. Flying at altitudes near the ground can also be dangerous since it
does not allow much time to recover.
NOTICE: Remember to initialize the model on flat or hard level surfaces. A solid or hard floor
is suggested. Soft level surfaces such as grass could cause issues due to a slight
unevenness. Uneven surfaces such as a car hood top is not advised. For best results, have
the model placed on a flat surface before plugging in the battery. This will allow it enough time
to initialize correctly.

***IMPORTANT CALIBRATION NOTICE!
Before each flight always power on your V-22 on a flat surface and allow up to 30 seconds for
the FC Controller to initialize. Do not move the V-22 during this initializing process. Once the
V-22 has initialized, PLEASE rotate the nacelles using the transition switch to full forward flight
mode and back to VTOL mode at least 3 times. If in the event you see the ailerons and the
nacelles deflect violently in opposing directions, DO NOT FLY. Follow the steps below to
calibrate the FC board for flight:
*Flight Control Board Calibration/Throttle Calibration*:
When you have powered on your transmitter and plugged in the V-22 flight battery, flip your
Nacelle transition switch from VTOL to Forward Flight QUICKLY up to 10 to 12 times. Do not
wait for the Nacelles to reach full down or full up. This is for calibration only. Flip in a quick Up,
Down, Up, Down, Up, Down about 10 times and then stop and wait. You should see the V-22
Ailerons deflect one direction and back to neutral. Possibly the Nacelles may perform the same
as well as the motors may initialize quickly. This will indicate FC Calibration successful. If you do
not see the motions stated above, perform the Nacelle switch flips again until you see the
results. This is a crucial step to insure your V-22 will transition smoothly! Be sure to transition
from VTOL to Forward flight towards a head wind if applicable and with plenty of altitude! For
more information, please watch Pete's V-22 Calibration and Flight video at the YouTube link

6: Center of Gravity Check
The following illustration provides details for the Center of Gravity (CG). The correct CG range is
between 5-30mm aft of the center of motor nacelle as shown in the photo below. If using a battery
with a larger/smaller capacity, please adjust the CG by adjusting the position of Li-PO battery.
WARNING: The model will be unstable/sensitive during flight if the CG is not correct. This will
result in loss of flight functions, pitch control authority, and sluggish controls.

NOTE: If you are experiencing bouncing flying character during Hover flight, it can be caused by
flying too low to the ground where there is rotor wash from the thrust/wind. Be sure to hover at least 8'
from the ground. It may also be unstable in hover if flown in windy conditions.

7: Flight
If you are an experienced pilot, flight can be achieved indoors or outdoors due to the V-22’s VTOL
capabilities. We suggest to choose a room measured at 20ftx20ftx20ft for VTOL mode ONLY. An
outdoor flying area with calm weather is best for maiden flights.
WARNING: Please organize the wires after the battery is put into the fuselage to avoid any
movement issues with the motor nacelles. Please check the motor nacelle movement to make
sure they work normally and double check the CG balance.
1. This model’s VTOL mode is similar to a standard quadcopter. Controlling the model may
feel similar to a standard quadcopter.
2. As a pilot, several styles of flight are available such as taking off in VTOL mode and
switching to airplane mode during flight.
3. VTOL flight may feel more stable than standard airplane flight because of onboard flight
controller and stabilizer.
4. When taking off in VTOL mode, it is suggested to fly the model higher than 100 ft. to make
sure it is able to clear any obstacles, and to be able to safely switch between flight modes
while keeping the throttle in position. The onboard flight controller and stabilizer will make
transition between flight modes are smooth as possible, but be sure to keep speed and lift
to prevent a stall.
5. When changing back to VTOL mode, it’s advised to be at least 100 ft. high.
WARNING:
1. When changing from standard flight mode to VTOL mode, please keep throttle up and
do not input elevator, rudder or aileron because the model itself will finish the transfer
smoothly. The model may lose control or crash if any additional inputs are applied on the
elevator, rudder or aileron while it is in transition mode.
2. Be sure the Li-PO battery still has sufficient charge before switching to VTOL mode to
land. If the battery is nearly drained before switching to VTOL mode, the model may
crash due to loss of power. Consult with the dealer for more information if needed.
3. When in VTOL mode, if pitch stability is affected by wind direction or other reasons,
remain calm and apply any of the necessary control inputs to land safely.

8: Maintenance
8.1 To power down, make sure to unplug the battery first before turning off the transmitter.
Doing so will help to prevent the receiver from potentially connecting with another system.
ALWAYS unplug the aircraft battery FIRST before powering down the transmitter!
8.2 Check the propellers for any damage and to be sure they are still secured.
8.3 For precautionary reasons, be sure to check the motor and ESC wires as they can come
loose from flight vibrations.
8.4 Check the fit between main wings and tail section on the fuselage.
8.5 Check to make sure the landing gear is secured.
8.6 Check the main wing screws as they may come loose when many flights have been logged
on the V-22.
8.7 Make sure all control pushrods and the clevises are secure. Check the clevis from flight to
flight for any cracks or splits.
8.8 Check control surface horns on the ailerons and elevator to make sure the arm backing is
tight.
8.9 On bright sunny days or warm days, avoid direct sunlight exposure to your V-22 to prevent
damage.
8.10 Store your V-22 in a climate controlled room.
8.11 If touch-up paint is needed, any model paint or acrylic paint will work fine. Do not use any
automotive paint!
