Feiyu FY 41AP-A&OSD Autopilot For Fixed Wing

  • Sale
  • Regular price $199.99

Brief Introduction

       FY-41AP is an inertial attitude measurement instrument used for FPV flight on fixed-wing aircrafts and multi-rotors aircrafts. It has an integrated OSD video overlay system that presents critical flight information such as power management, airspeed, altitude, and flight direction via its electronic compass, allowing for a clear visual flight while ensuring key information is within sight.

       Flight stabilization is achieved via an integrated 3 axis gyro, 3 axis accelerometer, 3 axis magnetometer and a barometric pressure sensor. This enables the module to accurately measure flight attitude, earth azimuth & relative altitude to achieve:

  • Extremely stable conventional flight pattern
  • Stabilized 3D flight
  • Automatically return to home (RTL)
  • Fixed altitude flight
  • Heading lock flight
  • GPS waypoint flight
  • Auto circling over a fixed GPS location.


Function Introduction

    ¡ñ Deactivated Mode - In this mode, the FY-41AP auto stabilization is turned off. The aircraft is completely under pilot control.

    ¡ñ 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.

    ¡ñ 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.

    ¡ñ Fixed altitude & Heading lock Mode - This mode maintains aircraft flight course & holds the altitude on activation. By using GPS data, the system automatically corrects flight course deviation & maintains straight-line flight.

    ¡ñ Waypoint Navigation Flight Mode - Enable you to fly fully autonomous, with up to 20 waypoints settings via the FY Ground Control Station (GCS) software.

    ¡ñ Auto Return To Launch Mode (RTL) - Upon activation of this Mode, the aircraft will automatically return to the Home point, maintaining its current altitude. Upon reaching the Home point, it will initiate auto circling.

OSD Video Overlay System Function

    ¡ñ First Person View (FPV) - FY-41AP has an integrated OSD video overlay system that presents critical flight information on the video for easy enjoy FPV, at the same time, Auto stable, Fixed altitude & Heading lock, Waypoint Navigation , Auto Return To Home function will make FPV operation more easy.

        OSD is an essential part for FPV. The FY-41AP can adapt both PAL and NTSC video signals. The entire adaptive process is completed approximately within 1 second.

        Integrated OSD Video Overlay System, FY-41AP overlays flight telemetry information onto video image. Information displayed includes: Altitude, Speed, Direction, Home Direction and many more.


You should to do the firmware upgrade separately for FY-41AP-OSD control module and OSD module. UART2 is the interface connects to the PC computer serial port to do the firmware upgrade for FY-41AP OSD module.If you want to upgrade the firmware of  flight control part ,pleaseclick on here.
