Adjusting Return to Home Mode:
1. Switch to RTH Mode, Important parameters “Home Direction,” “Roll Angle,” “Pitch
Angle,” and “RTH Throttle” shown on OSD shall be checked all the time.
Flying to certain height, switch to RTH Mode and check if these data are appropriate.
2. Adjust RTH parameters referring to these values. If the roll angle is too small to return
promptly, please increase the Max Roll. If the turning is to fast so that the RTH line is “S”
sharp, decrease the Max Roll and increase Rudder control (Yaw ctl)
3. Adjust Max Up and Max Down to make plane pitch up and down smoothly. (Too prompt or
slow are improper)
4. Based on how far and high expect to fly, adjust safe height as high as possible (If fly far than
2km, please adjust this value more than 150m). Please set cruise speed as “Safe speed” in RTH
menu.
