  • Page 2 Guilin Feiyu Electronic Technology Co., Ltd Dear Customer: Thank you for choosing FY31AP as your autopilot system. Please read this manual carefully before using the system to ensure proper use and operation. The installation and use of this device require some skill and knowledge in flying remote controlled fixed wing aircraft.
  • Page 3 While the GPS module enables the autopilot to calculate the flight course and exact location of the aircraft. If the FY31AP is not connected GPS module, the autonomous flight system cannot be engaged and it will function purely as a flight stabilizer.
  • Page 4 Upon reaching the home point it will automatically engage auto circling, while it waits for your further instructions. 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.
  • Page 5 Mode 2: Stabilized mode In this mode and your transmitter control sticks at center, the FY31AP will continuously send out controlling signal (aileron, elevator, rudder) to ensure the aircraft maintains a stabilized, horizontal flight and constant flight direction. In this mode FY-31AP will not allow acrobatic flights.
  • Page 6 Guilin Feiyu Electronic Technology Co., Ltd 10. FY-31AP Autonomous Flight Modes Three autopilot modes are incorporated into the FY-31AP, you can set it via a free receiver channel and a 3-position switch (named as “SW2”). Autopilot mode 1: Deactivated. The autopilot function is not activated , the flight modes are determined by the “SW1”.
  • Page 7 Guilin Feiyu Electronic Technology Co., Ltd 12. Gyroscope Re-set procedures： (1) Carry out this re-setting procedure only if the above occur. We do not recommend regular re-setting. It is not necessary and not recommended. (2) The stabilizer unit does not need to be in a horizontal position during initialization. However, you must ensure there is no vibration during this process.
  • Page 8 GPS provides the aircraft geographic positioning, altitude, speed and flight direction. Only if the GPS Data is available will the FY31AP perform its Autopilot Modes. In case GPS signal is lost during flight , the autopilot will keep its height and course （not lock）in automatic navigation mode ,but its course may gradually drift.

    23. CONTROL SURFACE MOVEMENT CHECK Install FY31AP as recommended in this manual, then proceed to confirm correct control surface movement direction in Mode 2 or Mode 3. In Manual mode (stabilization deactivated) confirm that the control surfaces do to react when your aircraft is tilted or rolled.

  • Page 18: Recording Your Aircraft Neutral Value

    24. RECORDING YOUR AIRCRAFT NEUTRAL VALUE 1. The FY31AP can record your aircraft best stabilization attitude in its memory. By recording this ‘Neutral Value’, the FY31AP can know how best to control your aircraft for optimum stability.
  • Page 19 Auto Stabilized Mode and the Neutral Value is already recorded. Now you need to fine tune your FY31AP stability gain via flight tests. For the first flight it is recommended that the gains not be set too high. To avoid excessive oscillation (flight overcorrection) put the gyro gain at mid point.
  • Page 20 Step 6: While in this Neutral Value, activate Mode 2 (Auto Stabilization Mode) for at least 2 seconds. Since Dip Switch No. 4 is ON, the FY31AP will now record your Neutral Value. After 2 seconds, switch back to manual mode or keep in the Mode 3 (Auto Stabilization Mode)and land your aircraft.
  • Page 21 Guilin Feiyu Electronic Technology Co., Ltd 28. Test for the Autopilot mode 2: Auto Return To Launch（RTL） After test well the stabilized mode, please keep the throttle at the cruising position，then switch the SW2 to the Autopilot mode 2(RTL), then the plane should return to the home point, and circle after it reach the home point.
