Adjusting Return to Home Mode:
1. Switch to RTH Mode, Important parameters “RTH Angle,” “Roll Control Value,” “Pitch Control Value,” and
“Throttle Control Value” 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.
11 FAQ and Solutions：
★When switching to Balance Mode, the elevator will lift up a bit because the “Elevate Angle in a level flight”
in the menu is defaulted as 5°. Which means the plane will rise a bit in a level flight to ensure a level route.
★If the CH1 has touched the edge but you cannot enter the menu, please check if the route setup is too small
on the remote control.
★It’s normal when the direction of compass and return arrow is inaccurate while testing on the ground. The
data will be calibrated by GPS in 10s after the plane takes off.
