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.

Control Horn and Servo Arm Settings

The table to the right shows the factory settings for the control horns and servo
arms. Fly the aircraft at factory settings before making changes.
NOTICE: If control throws are changed from the factory settings, the AR637T
gain values may need to be adjusted. Refer to the Spektrum AR637T manual
for adjustment of gain values.
After flying, you may choose to adjust the linkage positions for the desired
control response. See the table to the right.
