Adjusting Balance Mode:
Purpose: Stick and SUB-TRIM back to center, plane can be able to flight levelly.
1. Please increase control value (“ctl” in CTL menu) or plane’s control surface when the stability not good
enough (drift even stick back to center), and decrease it when the plane swings.
2. If plane pitches up or down when stick back to center, please adjust the “elevate angle” value (Do not
adjust through SUB-TRIM, otherwise RTH Mode won’t be precise.)
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.
