FY 40A by Feiyu Tech


FY-40A has an integrated three-axis gyro and three-axis accelerometer which controls the aircraft movement in three-dimensional space. Installation is very simple.By using your remote control, the unit can be turned on or off for the following functions:

Mode 1: Deactivated Mode ——In this mode, the FY-40A auto stabilization is turned off. The aircraft is completely under pilot control.

Mode 2: Stabilized Mode ——Level flight is automatically maintained, making flight simple, especially for beginners. If a pilot feels the plane is out of control, simply reduce input control and the plane will automatically recover level flight.

Mode 3: 3D Mode ——If no input is given by the pilot (all sticks in the middle position), 3D mode will lock the current aircraft attitude. Therefore the aircraft can be easily maneuvered to complete a variety of 3D flight with added stability & smoothness.
