Balance Mode and Return to Home Adjustment
Arkbird stabilizer has PID control, which can collect level flight throttle value automatically without any
parameter adjustment. If the most ideal situation expected, please refer to the following methods:
Once completing the first 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. Roll the plane to right and left 45 degree
after neutral point check to see if OSD horizon tilts accordingly and quickly.
Please fly on default and record on the ground. Observe the attitude through OSD and adjust parameters.
Adjusting Balance Mode
Purpose Stick and SUB-TRIM back to center, plane shall be able to have level flight.
1. Adjust PID parameters to the maximum under non-swing situation.
Please increase ctl value when the stability not good enough under Balance Mode (drift even stick back
to center), and decrease ctl value 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, or Return to Home Mode won’t be precise.)
Adjusting Return to Home Mode
1. While adjusting Return to Home Mode, “Home Direction,” “Roll Angle,” “Pitch Angle,” “Max Roll,”
“Max UP,” “Max Down,” and “RTH Throttle” shown on OSD shall be checked all the time. Flying to
certain height, switching to Return to Home Mode and check if these data are correct.
2. Adjust RTH parameters through above values. If the roll angle is too small to return back to home
promptly, please increase the Max Roll.
