Section 4: Installing the Aileron Control Horns

Parts Needed
Wings with ailerons and servos
Rocket City 8-32 Swivel Control Horn (2) (ROC01B)
Heavy-Duty 1/2 Servo Arms (2) (HAN3574)
Tools and Adhesives Needed
Ruler
Drill Bit: 8/32"
8-32 Tap and Drill (DUB363)
30-minute epoxy
Felt-tipped pen or pencil
Rubbing alcohol
Paper towels
Note: Remove the standard servo arms and mount
Hangar 9 Heavy-Duty 1/2 Servo Arms to each servo.
Step 1. Using a straight edge held in alignment (90°) with the
servo arms and with the hinge line as shown, mark the aileron
with a felt tipped pen or pencil where the straight edge intersects
the aileron hinge bevel at both servo locations.
Step 2. Measure exactly 1/4" rearward from the marks above
parallel to the hinge line and make another mark using a felt-
tipped pen or pencil. These will be the positions for the aileron
control horns.

Step 3. Using a 8/32" drill bit and hand drill, carefully drill a
8/32" hole through each aileron at the marked positions. [Drill
perpendicular (90°) to the aileron cross section rather than the
ailerons surface.] Be especially careful when penetrating through
the bottom surface of the aileron as it's easy to split out the wood
and rip the covering. Placing a wooden block under the aileron
and drilling slowly will prevent these problems. If you choose to
use the counter sink screws included in the Hangar 9 Hardware
Package, counter sink the top of the aileron to allow the screws
to fit flush.
Note: Hardwood blocks (hardpoint) are located below the
sheeting; you will be drilling through these.
Step 4. Using an 8-32 tap, tap the holes that you just drilled in
the ailerons.
