Step 1. Screw a Clevis onto the inboard screw horn until the
bottom of the clevis is 5/8" from the aileron.
Step 2. Install a 4-40 ball link five to six turns onto a 4
4-40 Pro-Link. Screw the opposite end of the linkage five to six
turns into the clevis that is to attach to the swivel control horn
that was installed in the previous step. Attach the linkage to the
swivel horn on the inboard servo only with the bolt supplied.
Adjust the linkage length until the hole in the ball link aligns
with the outer hole in the servo arm when the aileron is neutral
and the servo arm is centered.

Note: Hangar 9
threads on one end and left-hand threads on the other,
allowing for easy, accurate adjustment without
disconnecting the linkages. Consistently putting the
right-hand threads toward the servo arms on all servos
will prevent you from getting confused as to which way
to turn the Pro-Link to lengthen or shorten the linkage.
Hangar 9 also offers a Pro-Link Wrench (HAN3558) to
make adjustments easier.
Step 3. Using the 4-40 screws and nuts included in the control
horn package (don't substitute a standard screw), attach the ball
link to the outer hole in the arm from the bottom side as shown on
both servos. The sequence is screw, ball link, servo arm, and nut.
Don't forget to use threadlock. The tapered standoff is not used.
