With the control h orn in position apply painter’s masking
tape around the control horn base. Put the tape up to
the base edge. Not under or over it.
Assemble a rod end to the control horn using a supplied
machine screw and nylon lock nut. (Assembling the ball
link to the control horn at this step will help keep the
control horn halves parallel during installation.)
Remove the control horn leaving the tape in position.
Using a new hobby knife blade lightly cut through the
covering but not into the balsa sheeting. Cut inside the
tape edge about 1/16”.
Use sand paper to roughen the lower portion of the
control horns on both sides. Roughen one side of the
base plate. This will help the epoxy bond to the control
horn parts.
Apply epoxy to the slots in the elevator. Use a pin to help
push some epoxy into the slots.
Apply epoxy to the control horn assembly and insert it
into the elevator slots.
Wipe away excess epoxy using a paper towel soaked with
denatured alcohol. Use an upward rolling motion as you
wipe the excess epoxy to lift it from the surface. This
helps reduce smearing the epoxy.
Check the alignment along the hinge line as you did when
you test fit the control horn. Reposition as needed. Allow
the epoxy to partially cure. Peel away the masking tape
after the epoxy is securely holding the control horn in
place and still soft enough to easily remove the tape. Set
aside and let the epoxy fully cure. (Repeat on second
elevator half if you will be using 2 elevator servos.)
