ing the helicopter.

Pre-flight checklist
Check that the transceiver's battery is fully charged.
Check whether the gyro tape is torn or peeled.
Turn on the transmitter / receiver and initialize the gyroscope.
Check whether the servo type setting matches the servo being used (Rudder /
Swash).
Check that the servo horn is neutral and perpendicular to the push rod. (Rudder /
Swash).
Confirm that the maximum servo movements are not physically bound through
-
out the range of motion. (Rudder and swash).
Check that the gyro is operating in the correct mode (AVCS or normal) (Rudder).
Check whether the operation of each input matches the operation of the tail rotor
/ swash plate.
When rotating the aircraft body, make sure that corrective action is performed in
the correct direction.
Is the gyro sensitivity set correctly for all flight conditions? Also, check whether
it is operating in the correct mode (AVCS or normal).
