" long
4-40 linkage. Screw the opposite end of the linkage into the
swivel control horn that was installed in Step 2 five to six turns.
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
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 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. The sequence is screw, ball link, servo arm, and nut.
Don’t forget to use Blue Locktite. The tapered standoff is
not used.
