Fuelproofing

Fuelproof areas that will be exposed to raw fuel
or exhaust residue. These include the fi rewall, the
entire fuel tank compartment, the underside of
the hatch and inside the fuselage around the wing
saddle area (the insides of the “windows” and

cabin sides). Use 30-minute epoxy (you may thin
the epoxy with alcohol so it is easier to brush on)
or fuelproof model airplane paint.

Final Hook-ups & Checks

Connect the Servos

The nylon parts in this photo have been dyed black

for illustration clarity.

1.

Cut a 36" wire rod (included) to a length of

30" (including the threaded end). Connect a nylon
clevis to a nylon control horn, then thread the clevis
approximately 20 turns onto the rod.

❏ ❏

2.

Use a new #11 blade to cut the covering

from the pushrod guide tube exits in the rear of the
fuselage, then insert the pushrod into the elevator
guide tube. Position the control horn on the elevator
in the location indicated on the plan so that the
holes in the control horn align with the hinge gap
as shown in the sketch.

❏ ❏ 3. Use the holes in the base of the control

horn as a guide to drill two 1/16" holes through
the elevator, then mount the control horn to the
elevator with two 2-56 x 1/2" screws and the

control

horn plate

.

❏ ❏

4.

Make another pushrod assembly and mount

the control horn to the rudder the same way as
the elevator.

❏ ❏

5.

Follow the instructions included with your

radio to hook-up and center all servos. Center
the elevator servo arm, then use a felt-tip pen to
mark the wire pushrod where it crosses the holes
in the arm.
