Main advantage


Grate stability and wind resistance;


Operating hand lines better, and is suited to do 3D acrobatic movement;


Support firmware upgrade, easier to product upgrades.

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

Mode 1(Full Balance Mode)

in this mode, the Quad flight is fully stabilized on all 3 axis, resulting in extremely leveled flight. Suitable for aerial photography, videography, FPV and beginner quad pilots.

Mode 2(Aerobatics Mode)

In this flight mode, the controls to the Quad motors are very responsive. Specifically for skilled Quad pilots for sports flying, fast forward flights (FFF), stunts, etc.

Rc-toys Multi Rotor safty Tip Keep your PROPS OFF not installed until you are fully conversant/understand in full the functions of your Tx in full including TRAV (end Points), the arm and disarm procedures - realise that for a noob skiping or out-of-order set-up steps or moving sticks, or even static - PROPS may start at anytime without warning. Never install props prior to calibration of the ESC and testing the gyro orientation, and arm/disarm testing of the board - YOU are responsible - make sure your actions and your Copter is safe. Never ASSUME the props will not start - removing the props removes the risk.
