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. (Refer to CTL menu
）
Roll the plane to right and left 45 degree after neutral point check to see if OSD horizon line tilts accordingly
and quickly.
Please fly on default and record OSD video on the ground. Observe the attitude through OSD and adjust
parameters.
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
“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 Dow
n to make plane pitch up and down smoothly. (Too prompt or slow are
improper)
