Section 8: Installing the Elevator and

Rudder Control Horns

Parts Needed

• Fuselage assembly

• Control horn w/back plate (2)

• Mounting screws (6)

Tools and Adhesives Needed

• Drill

• Drill Bit: 1/16"

• Felt-tipped pen or pencil

Important: When installing the control horns, it’s

important that the holes in the control horns where the

pushrod attaches are directly in line with the control

surface hinge line.

Step 1

To locate the elevator control horn position, measure the center

bottom of the elevator. Mark the elevator as shown with a felt-

tipped pen or a pencil. This mark will be the center of the elevator

control horn location.

Step 2

Place the center of the control horn on the elevator at the mark

made in the previous step. Align the holes in the control with the

hinge line as noted above. Mark the mounting holes of the control

horn with a felt-tipped pen or pencil.

Step 3

Drill 1/16" holes through the elevator as marked. Make sure to

drill these holes parallel to each other to allow the back plate of

the horn to ﬁt properly.

Step 4

Using the three screws and the back plate provided, attach the

elevator control horn and fasten in place with a Phillips screwdriver.
