Section 7 – Elevator Assembly

Note: The technique for installing the control

horns in the elevators is similar to the aileron

control horn installation.

Step 4

To properly locate the position of the control horn on

the bottom of the elevator, measure inward 7/8" from

the root and rearward 1/4" from the top of the bevel.

Step 5

Using a 5/32" drill bit and drill press, carefully drill

through the elevator at the above marked position. It’s

important to drill 90° to the top of the elevator. Be

especially careful when penetrating through the

bottom surface of the elevator, as it’s easy to split out

the wood and rip the covering. Placing a wooden

block under the elevator and drilling slowly will

prevent these problems. If you choose to use the

countersunk screws included, countersink the holes

in the top of the elevator to allow the screws to fit

flush.

Step 6

Use an 8-32 tap to thread the holes just drilled

in the elevator.

Step 7

Mix a small amount of 30-minute epoxy and lightly

coat the inside of the threaded holes and the 8-32 x

2" Hangar 9® screw. From the top of the elevator,

thread the 8-32 screws into the tapped holes and

tighten. Wipe away any excess epoxy with rubbing

alcohol and paper towels.

Step 8

Screw the molded swivel link onto the 8-32 screw

until the distance from the elevator surface to the

bottom of the link is 1

”.

Step 9

Cut off the first section of two of the hinges. This is

done to clear the tube installed in the elevator.
