5. Cruise flight (Keep straight &constant-height flight).
6. Gyro normal balance and 3D balance. Hover mode.
7. Fence mode（Auto Switching to Return-to-Home Mode while flying out of the rectangle area specified.）
8. 4 Way point flight, coordinate set by radio stick.
9. "Launch Assist" function which can help to control throttle and elevate angle when take-off.
10.RSSI port available, 10 channel PPM port supportable.

  • Page 21 Arkbird FPV “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. These data will tell you if the control values are proper and will help you judge which parameter needs to be sub-trimmed.
