INSTALL FRONT PUSHROD GUIDE TUBES

D 1. Install the plastic pushrod guide tube for the
nose gear steering pushrod if you are building
the tricycle gear version.
D 2. Insert the 5/32" wheel collar into the nylon
nose gear steering arm and screw in the 6-32
x 1/4" screw. Install this steering arm onto the
nose gear.
D 3. Insert one of the long threaded pushrod wires
into the nosegear pushrod guide tube (threaded
end forward). Screw a nylon clevis onto the
threaded end of the pushrod until the threads
protrude into the clevis opening, and attach
the clevis to the steering arm. Cut off the excess
pushrod wire at the servo end. Leave this push
rod and steering arm in place, as they
would be very difficult to install later.
D 4. Install the pushrod guide tube for the throt-
tle pushrod, keeping it as close to the fuse side
as possible in the fuel tank compartment. Glue
this tube to F-l and F-2.

INSTALL FUEL TANK

NOTE: It is physically possible to install up to a
24-ounce fuel tank in this airplane, but we recom-
mend that you use a 14 or 16 ounce tank for ease of
installation and to avoid excessive shifts in balance.
1. Cut out the cross piece at the top of F-2. (In
the die-cutting process we have started these
cuts for you).
D 2. Glue the 1/8" x 2-1/4" x 4" balsa fuel tank
support to the bottom of the hardwood rails
in the location shown on the plan. NOTE: If
you are not using the hardwood rails, use a
few scraps of balsa to anchor the fuel tank sup-
port to the fuse sides.
3. Wrap the fuel tank with soft foam rubber
and lay it in place on the fuel tank support.
Adjust the position of the tank up or down by
adding foam as necessary, until the center of
the tank is approximately at the same level as
the fuel intake on the carburetor.
D 4. Drill holes near the top of F-l and install
silicone fuel tubing from the tank to the carb
and to the pressure tap on the muffler. We
recommend using a fuel filter in the line from
the tank to the carb.
D 5. If you have not already done so, take a few
minutes now to fuelproof the hardwood en-
gine mounting rails, the front of F-l and the
fuel tank compartment, as some of these areas
may be difficult to get at later on.
