you will ensure a smooth operating surface with no binding. Seal
the bottom of the hinge gap with a strip of Ultracote or Blenderm
tape. Be sure to fully deflect the control surface when applying the
tape or Ultracote to allow full deflection once the gap is sealed.

Thread 2 of the heavy duty ball links onto one of the titanium
pushrods. Remember that the ends of the pushrods are reverse
threaded so that they can be adjusted like a turnbuckle without
removing the linkage. Insert a 3mm socket head cap screw into the
ball link and into the servo arm. If using the SWB arms you will
need to drill out the hole to accept the 3mm bolt. Secure with a
3mm nylon insert locknut.

Place the servo arm onto the servo (which you should have
electronically centered in a previous step) and make sure the
elevator is in the neutral position. Adjust the ball links until the
linkage fits between the composite control horns and lines up with
the pre-drilled top hole. Insert a 3mm socket cap screw into a
washer, through one side of the composite control horn, through
the ball link, and finally through the other composite control horn.
Secure with a 3mm nylon insert lock nut. Use blue Loctite on all
bolts! See finished set-up below.

As mentioned previously, you may need to adjust the size of the
servo arm exit slot to achieve maximum travel. A ¼” Drum sander
in a moto-tool makes quick work of this. Repeat these steps for the
other stab/elevator half. Before you set aside the stabs take a
