tremble.
The sound of the helicopter's
main rotor becomes smaller.
The helicopter battery voltage
is low.
Charge the battery or replace
with a fully charged.
The helicopter does not
respond or cannot fly
smoothly
Signal binding failed. Re-bind, the helicopter must
be placed horizontally when
binding.
When the helicopter took off,

Brushless governor failure or
poor contact
Check the joints or replace
the governor.
The main rotor is deformed,
the horizontal axis is bent, and

The propeller clamp screw is
too tight, causing the main
propeller to fail to rotate.
The horizontal axis is bent, the
horizontal axis screw is not
tightened, and the propeller
bearing is worn.
Foreign matter in the steering
gear causes jitter,
The upper swashplate and the
lower swashplate are loose,
Deformed or damaged tail rotor
Replace the horizontal shaft,
tighten the horizontal shaft screw,
and make it move smoothly.
Replace the bearing, remove the
steering gear, remove the foreign
matter of the steering gear,
Press the upper swashplate and
the lower swashplate tightly, and
replace the tail rotor.
Replace the main propeller,
Replace the spindle,
Replace the tail rotor,
Properly loosen the propeller
fixing screws
After the code matching is
successful, start the helicopter,
