The Attitude Flight Stabilization System (AFSS), which is the heart of the FY-90Q, is an integrated 3-axis gyroscope and 3-axis accelerometer. AFSS forms a comprehensive inertial based navigation platform that calculates 3D flight attitude using proprietary FeiYu Tech algorithm.

When in Full Balanced-Mode (Mode 1), the AFSS detects any changes to the model's horizontal attitude. If attitude change is detected, the unit will send out controlling signals to change the Quad’s four motor speed to maintain stability and balance.

The FY-90Q supports two Flight Modes. Selection of Flight Modes is via a free channel on your Receiver:


Model Description
