FY-41AP OSD+Flight Stabilization System+Autopilot+20WP




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.
The new FY-41AP with its enhanced Altitude Control and GPS module, can now realize improved pinpoint inertial navigation and automatic piloting. ElectroniaRC like this autopilot.

Manual, upgrade firmware, setting for FY-41AP version: wing aircraf and multicopter

        - FY-41AP can connect the air speed sensor which automatically controls throttle and can make the aircraft more stable

        - FY-41AP comes with a power management module with an integrated current sensor. You can power both your FY-41AP and your servos at once, or utilize the power management module to charge them separately.

         - You can set up parameters using your remote control or your computer.



   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.    

                   Package include 

 Feiyu tech kindly remind you: 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 ,please click on here.

GCS V4.1 ground station software



 GCS ground station software, used to set the flight parameters, mission planning, monitoring in flight. Software integration of electronic map function can through the map software () the Google earth live map out into the GCS software. The main function is

    Parameter SettingsControl parameters setting, course setting, etc
    Real time monitoringIt can monitor flight attitude. And via the GCS software you can change the flight altitude in real time and realize the mouse click flight.
    Record and monitoring flight—You can monitor and download flight path via the GCS software in your computer.

FY-41AP Single Module Function


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

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.

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.

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.

Auto Circling Mode –On activation, the plane will maintain altitude and flight speed, while initiating a counterclockwise circle, but this is not hovering around a fixed point, is likely to be blown away from the original place of circle.


FY-41AP with GPS function


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.

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

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

Auto Circling Mode –On activation, the plane will maintain altitude and flight speed, while initiating a counterclockwise circle. The centre of the circle is the point of activation at a default radius of 80 meters (can be changed via FY GCS).

GCS software By using a field computer and connecting the FY41AP to an FY Data Radio via the UART port, you can set the FY41AP flight parameters, monitor the flight progress & record / reply the flight via the FYGCS software. For more information, please refer to the FY Data Radio manual.
