    Balance Mode and RTH Adjustment (Very Important) Arkbird’s default parameters will be ok for most plane types. But if the most ideal situation expected, please refer to the following methods: First time installation, do a neutral point alignment. Plane shall be put paralleled to the ground before neutral point check, moving aileron stick left and right to get start.

    CG and travel angle to make plane balanced. Arkbird can produce compensation when CG & travel angle is not appropriate, but it is not mechanical stable, there would be hidden trouble under RTH mode. So firstly make sure plane can fly stably in horizontal under Manual Mode.
  • Page 27 A： Adjust remote control rudder angle to 100% and sub-trim back to center. Check carefully in reference to the “Debugging Skills for Balance and RTH Mode” chapter of our instructions. Make ground video recordings. When switching to RTH or other autonomous flight modes, Roll/ Pitch inclination value and throttle control value will be shown at the bottom right corner of OSD.

  • Page 28: Attentions

    Attentions Please read through carefully: 1. The design purpose of autopilot is to keep balance of flight, it is not able to manipulate plane or prevent stall. You must have sufficient experiences of fixed wing to control the flight. 2. The autopilot is only for small-scale RC model. For safety concern, please do not install in plane for aerial photography which might fly over crowd.
