MAINTENANCE
The Micro Mosquito was engineered to be a light weight robust structure; however, as a real flying helicopter it is possible to
damage the rotors or structure. Use these simple procedures to repair your helicopter and get back into the air.
TROUBLESHOOTING
CORRECTIVE ACTION:
CAUSE:ISSUE:
Helicopter will not start,
LED on helicopter is off
1) Helicopter not turned on.
2) Battery is not charged.
3) Helicopter was not set to OFF during charging.
4) Rotors locked for overload protection.
1) Turn helicopter on.
2) Ensure helicopter is off and charge battery.
3) Ensure batteries are fresh.
4) Adjust helicopter's on/off switch to OFF, then switch on again.
Helicopter will not start, LED
on helicopter is ON.
1) Transmitter is not turned ON.
2) Speed control is not initialized .
3) Battery is low.
1) Turn transmitter on.
2)
Push UP/DOWN completely to UP, then back to DOWN to
initialize speed control.
3) Ensure helicopter is OFF and charge battery.
Helicopter is flying too high.
1) You need to reduce the throttle.
1) Move the throttle stick down.
Helicopter is flying too low.
1) Needs more power/throttle.
2) The battery in the helicopter is low.
3) The batteries in the charger are drained.
1) Move the throttle stick up.
2) Ensure the helicopter is OFF and charge the battery.
3) Remove batteries from charger & replace
with new batteries
and charge the helicopter again.
Helicopter doesn’t hover.
1) The helicopter drifts forward.
2) The helicopter drifts backwards.
1) Compensate with the back stick to hold helicopter in position.
2) Compensate with forward stick to hold helicopter in position.
Helicopter doesn't move
fast enough.
1) The battery charge is getting low.
2) The tail rotor is damaged.
3) The helicopter center of gravity is no longer
correct.
1) Turn the helicopter off and charge the battery.
2) Replace tail rotor with new unit from the replacement
rotor kit (available in stores)
3) Tape a paper clip or other light weight item under the nose
of the helicopter.
The Helicopter always spins
in hover.
1) Trim control is not set correctly.
2) The rotor blades have sustained damage / or
wear from use:
a. Helicopter spins counter clockwise.
b. Helicopter spins clockwise.
1) Adjust the trim control knob.See the FLYING TIPS section.
2) Gently bend more curvature into the blades.
a. Adjust the top rotor blades.
b. Adjust the lower rotor blades.
Helicopter doesn’t fly backwards
1) The helicopter only flies backwards briefly then
spins to fly forward.
1) Aerodynamics make flying backwards more difficult than
flying forwards and this flight pattern is normal, practice flying
backward and control the left/right motion to keep the tail
pointed in the direction you desire.
Helicopter fails to take off.
1) The large, top cog (under the bottom rotor) is
misaligned.
2) Shaft lock under the body has detached from the
drive shaft.
3) The rubber stopper on the top of the drive shaft
has detached.
1) Realign with equal spacing between the pair of large cogs.
Large, top cog should be in contact with the small front cog
(top).
2) Replace shaft lock as shown.
3) Replace the rubber stopper (part separately available inside
Replacement Kit, 60-4461).
Broken Rotor
If the ring or centre is broken – replace with new rotor. (spare part kit available separately.)
If the blades are broken or cracked, you can use clear tape to fix. Hold the broken or cracked blades in the correct position
and using as little tape as possible, secure the rotor together. Trim or fold over any extra tape. If too much tape is used it
will throw out the balance and hinder your stable flight.
Broken Leg
Use clear tape or Crazy glue to reattach the broken leg (under adult supervision).If the leg is lost,try to use a piece of the
plastic tube from a Q-tip to replace the broken part of the leg (plus a little glue).
Rotor Head
If the ring or centre (head) is broken – replace with new rotor. (spare part kit available separately.)
If it is only bent out of shape try to use some force to permanently bend it back again.
-Be careful to not destroy the hinges, the rotor must be able to tilt absolutely freely (when you tap on it, it should tilt up and
down for at least 2 seconds before it comes to rest again – if this is not the case the helicopter will be unstable and
start to oscillate).
Tail Rotor
If the propeller is broken replace. (spare part kit available separately.)
Broken motor not possible for the average customer to change. Remove the propeller and add a little weight to the front
e.g. a metal paper clip attached to the motors (hold by the motor magnet) to get a slow constant forward speed.
Tail Boom
Will normally not break.
If problems it is possibly the mounting into the body that is the problem – be careful as there are two very thin wires
for the tail motor going inside the boom. Try to glue the boom to the body without pulling it out first.
(the thin wires can be damaged).
