Step 10
With the servo at the neutral position and radio on, attach
the servo arm to the servo. Place it on the spline that sets
the arm closest to parallel with the hinge line. (This will be
fine-tuned later.) Turn off the receiver and manually turn
the arm so it is parallel with the hinge line.

Step 11
Temporarily remove the setscrew from the control horn
and remove the clevis. Thread the clevis onto the 3-inch
(76mm) linkage and adjust the length to center the aileron.
Remember to keep the aileron servo arm parallel to the
hinge line while adjusting the linkage. Reinstall the set
screw to attach the clevis to the control horn.
Note: A small amount of threadlock is
recommended to keep the set-screw secure.

Step 12
Turn on the radio and adjust the sub-trim in the
transmitter until the aileron is at the neutral position.
Deflect the stick to full right aileron and adjust the travel
adjust so the deflection is 40 degrees. Repeat this for full
left deflection and adjust for 40 degrees.
