About the FY31AP:

FY31AP is an inertial attitude measurement instrument used for automated stabilization of fixed wing model aircrafts and two axis camera gimbals.  FY31AP has an integrated three-axis gyro and three-axis accelerometer which controls the aircraft movement in three-dimensional space.  

About the Hornet OSD:

The Hornet- OSD overlays flight telemetry information onto your downlink video image. The telemetry information displayed includes flight altitude, flight speed, flight direction, and home direction and so on. You also can save the telemetry information to a MICRO SD card, then trace playback via FYGCS software. The Hornet-OSD can be connected to the FY-21AP, FY-31APand FY-3ZT systems to display autopilot telemetry data, or to a GPS receiver to display positioning data. Hornet-OSD automatically adapts to either PAL or NTSC video input and confirms if there is a MICRO SD card or not. The adaptive processes are within 2 Seconds.

Level flight

When stabilization is activated, the FY31AP will automatically control the aircraft for smooth easy flying. For beginners in RC aircraft flying, this is advantages as it makes flight easier and increases the student pilot self-confidence. The system can be activated throughout the entire flight duration, from take off to landing.

Emergency Recovery 

If you lose orientation release all control sticks, maintain throttle and switch ON the FY31AP. The unit will automatically send the correct signals to balance of the aircraft and regain level flight, giving you time to get your
orientation and fly the plane back to safety.

Autonomous flight

With the GPS Receiver connected, the FY31AP will enable you to fly fully autonomous, with up to 8 waypoint settings using the FY Ground Control Station (GCS) software.

Ground Control Station

The FY GCS software will enable you to fly autonomously to up to 8 waypoints, display in-flight telemetry data, and record that flight for replay and analysis (this requires the optional Data Radio hardware).

Return to Home

You can set autonomous return to home via a 3 way switch or through your failsafe setting, enabling you plane returning to home should it lose your transmitter signal. Upon reaching the home point it will automatically engage auto
circling, while it waits for your further instructions.

Automated circling

By activating this function, the aircraft will automatically circle the selected area at a fixed altitude. You can set the circling radius.

First Person View

For long-distance RC flight via video transmitter, the FY31AP will maintain the balance of your aircraft. You only need to control the heading of your aircraft and enjoy the view.

Firmware upgrade

The FY31AP firmware is upgradable by connecting to your  Feiyu Electronics Company computer via a USB TTL cable. As Feiyu Tech continuously improves the FY31AP system, firmware upgrades will be released periodically.
