Roll, pitch and yaw. Roll, pitch and yaw are rotations along the natural axes of the helicopter (or any aircraft). A rolling movement is where the helicopter rotates along a line along its length using lateral cyclic inputs (aileron), eventually turning from right way up to inverted while maintaining the helicopter's heading.
How Does A RC Helicopter Gyro Work. The RC helicopter gyro is a small device that detects any yaw (left or right swinging) movement of the helicopter and automatically sends a command to the tail rotor servo to correct and stop/limit the yaw movement.
