The final electronic component mounted on the helicopter that plays a crucial role in its stabilization is a gyro. A gyro essentially consists of a spinning wheel of a certain size and mass fixed on a shaft. When its spinning wheel rotates sufficiently fast at a predetermined speed, the whole unit becomes a reference for comparison thanks to the gyroscopic effect.
If the helicopter starts oscillating or moving from its set path, these disturbances affect the gyro. The latter's sensors instantly capture these changes and send an electric signal to the receiver.
The stabilization electronics then processes the signal and commands the control servos on the helicopter to alter their position appropriately to stabilize it.
