Step 4
Attach the clevis to the control horn. Position the control
horn on the elevator so the control rod is straight, and
the holes in the control horn aligns with the hinge line
of the elevator. Mark the position for the mounting holes
using a felt-tipped pen.
Step 5
Drill three 1/16" holes at the locations marked in the
previous step. The holes only need to be 5/16" deep:
don’t drill through the top of the elevator.
Step 6
Install one of the #2 x 3/8" screws in a hole drilled,
then remove it. Place 2-3 drops of thin CA into the hole
to harden the wood. This will eliminate the potential of
the screw pulling out of the wood. Repeat this for each
of the three holes.
Step 7
Attach the control horn using three #2 x 3/8" screws.
Step 8
Center the elevator servo electronically using the radio
system. Install a servo arm onto one of the elevator
servos. Physically place the elevator control surface
in neutral. Mark the pushrod where it crosses the
holes in the servo arm.
