Step 1.
Screw a 4-40 ball link five to six turns onto a 5" long
4-40 linkage. 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 Section 3. 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 Titanium Pro-Links feature right-hand
threads on one end and left-hand threads on the other,
allowing for easy, accurate adjustment without discon-
necting 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
linkage to lengthen or shorten the link. Hangar 9 also offers
a Pro-Link Wrench (HAN3558) to make adjustments easier.
Step 2.
Using the 4-40 screws (don’t substitute a standard
screw) and nuts included in the Rocket City package, 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 blue Locktite. The tapered
standoff is not used.
Step 3.
Temporarily plug the servos into the receiver and set
the programming to get the aileron functioning correctly (see
page 32 of the manual for correct control throws). Only the
inboard aileron is driving the aileron at this time.
Step 4.
Set the control horn for the outboard servo the same
distance from the aileron centerline (not bottom surface of
aileron) as the inboard servo.
