4. Insert two 12" pieces of fuel tubing through the hole in
the firewall. Place the fuel tank partially into the fuel tank
compartment and connect the lines to the tank. Work the
tank into position, centering it in the compartment. Cut the
fuel tube to the carburetor so the there are no sharp bends
or kinks in the fuel line.

1. Mark the position of the muffler cut-out onto the side
of the fuselage. Remove the engine at this point to prevent
any wood from entering the engine. Use a hobby knife
and/or razor saw to cut the fuse side to allow for at least
1/4" clearance around the muffler. Be sure to paint the
exposed wood with a fuelproof paint or epoxy.
❏
2. Locate the position of the needle valve according to your
specific engine. Cut or drill the fuselage side to allow for ease
of needle adjustments. Leave a space around the needle so
that any vibrations will not affect the needle setting. Install the
muffler. Cut the tank pressure tube to the proper length, then
attach it to the muffler.
Note: A small piece of music wire or a cut down hex
wrench can be used to extend the needle if it does not
reach through the fuse side.

3. Fit the hatch in position. By measurement, determine
where to drill 1/16" holes in the four corners of the hatch to
pass through the center of the four underlying hardwood
blocks. Tape the hatch to the fuselage using masking tape
to prevent the hatch from moving while drilling the holes.
After drilling these holes, remove the hatch and enlarge
only the holes in the hatch to 3/32". Soak the inside of
the holes in the hatch with a drop or two of thin CA to
harden the balsa. Clean out the holes with a 3/32" drill bit
after the CA has cured. Attach the hatch with four #2 x 3/8"
sheet metal screws.

1. Lightly sand the edges of the three plywood wing
hold-down plates to remove any rough edges. Note that
one of the plates is slightly wider than the other two. This
plate is to be placed on the bottom. Use 30-minute epoxy to
glue the three pieces together. Clamp the wing hold-down
plates together or weigh them down on a flat surface while
the epoxy cures.
