Functions:<br />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:<br /><br /><br /><br /><br />Mode 1: Deactivated Mode: In this mode， the FY - 40Aauto stabilization is turned off. The aircraft is completely under pilot control.<br /><br />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.<br /><br />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 and smoothness.<br /><br /><br /><br />Supported Aircraft :<br />1.
