Replace the main rotor blades, bent
main or feathering shafts, loosen the
blade grips.
Problem Cause Solution
Main rotor blades shake during flight.
Feathering shaft or main shaft is
bent. FS screw is not tight enough.
possible broken gear in the servo,
causing shakes. The loose between
the swashplates.
Replace the lateral axis. Tighten the
lateral axis screw. Change the Bearing.
Remove the servo, and clear debris.
Compress the swash plates. change the
tail rotor blades.
The sound of the main rotor becomes
softer or drop in head speed.
Low battery voltage of helicopter.

fully charged battery.
Helicopter has no reaction or does
not fly smoothly. Failure of binding.
Rebind the helicopter and transmitter,
make sure you place the helicopter at
