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 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.
• Turn the linkage clockwise
or counterclockwise until the
control surface is centered.
• Attach the linkage to the
servo arm or control horn
after adjustment
• To adjust ailerons and flaps, find
the openings in the servo covers.
A small section of decal may
need to be removed to access
hole. Use a Phillips screwdriver to
loosen the keeper screw, adjust
surface and re-tighten screw.
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.
