Control Surface Centering and Adjusting a Ball Link

IMPORTANT: Perform the Control Direction Test before performing control
surface centering.
While SAFE is inactive, mechanically center the control surfaces.
IMPORTANT: Correct operation of the SAFE system requires sub-trim and trim
at 0.
After binding a transmitter to the airplanes receiver, set the trims and sub-
trims to 0, ensure the servo arms are in the correct positions, then adjust the
linkages to center the control surfaces.

After flying, you may choose to adjust the linkage positions for the desired
control response. See the table to the right.
• Turn the linkage clockwise

control surface is centered.

servo arm or control horn
