First you need to find the pre-drilled holes for the steel posts.
Install the aluminum control horn
assemblies to each surface with the M4 bolt in the down position. Use blue loc-tite on the aluminum
base to ensure the bolt does not try to back out under vibration. Screw on the horns on to the posts.
Do not use loc-tite installing the horn.
Make sure your elevator servos are centered and mount your servo arms parallel to the hinge line.
Take some masking tape and tape the elevator counter
balances to the stabilizers so that they are in a center
position.
Screw in your two HD ball links onto the
counterclockwise ends of the 2.5” H9 push rods and
screw the other end into the control horn. Ensure
everything is still centered. Don’t forget to add
locknuts to the 4/40 bolts attaching the ball link to the
arm.
Ensure aileron servos are centered and mount your
arms parallel to the hinge line.
Be sure that you install the horns at the same height from the hinge line (see attached). By doing so you
will have very little servo matching to do afterwards.
Screw in four HD ball links onto the counterclockwise ends of the 2.5” H9 push rods and screw the
other end into the control horn. Ensure everything is still centered. Don’t forget to add locknuts to the
4/40 bolts attaching the ball links to the arms.
