With the engine and mount still on the firewall, mark the location of the throttle
tubing hole. This hole lines up with the hole in the engine s throttle arm and, in the
case of the Norvel, is located on the far left side of the firewall. Remove the
mount and engine from the firewall. Drill the two fuel line holes with a 5/32" dia. bit
and use a 5/64" dia. drill bit for the throttle tubing hole. The throttle pushrod tube
will be installed later in these instructions.

Use the 1/16"x3" balsa sheet provided to cover the top front of the fuselage from
F-3 forward, over the engine compartment to the front of the fuselage sides. This
is most easily done using two pieces of wood, joined at the center, over the 1/8"
sq. balsa stringer.
b.
Edge-glue the sheeting to the fuselage
sides first. Then apply glue to the
formers and roll the balsa sheet over
them to the center of the 1/8" sq.
stringer.
c.
Lightly sand each joint with a sanding
block.
Electric Version
: The 1/16" balsa nose sheeting is applied in exactly the same manner as the glow version. The sheeting
covers F-1 back to F-3.
20.
Glue the bottom 3/32" laser-cut balsa nose doubler in place between the fuselage
nose doublers and against the bottom face of the firewall. The doubler fits flush
with the fuselage sides with the half-circle drain hole cut out facing to the rear.
When gluing this doubler in place, match the bottom curvature of the nose. Lightly
sand the doubler and fuselage sides smooth.
21.
Glow Version Only
: Use your Dremel Tool and drum sander bit to begin clearing
out the top front sheeting to accept the engine and mount back to the firewall. As
shown in the photo and on the plans, the sheeting is cleared enough to cleanly
accept the engine and its muffler, with approximately 1/8" clearance all the way
around. As you proceed, frequently check the fit until you are able to get the
motor mount flat against the firewall. Note that the configuration of the Norvel
engine and muffler leaves the muffler almost, but not quite, touching the firewall.
This works fine in actual practice.
22.
Locate laser-cut 1/16" plywood main landing gear brace. Lightly tack-glue the
brace in place to the bottom of the fuselage, over the landing gear wire slots cut
earlier into the bottom longerons. After final sanding of the fuselage, this brace
will be removed, allowing you to mount and glue the landing gear in place in the
fuselage. Only after the wire landing gear is in place, will the sanded landing gear
brace be final-glued to the fuselage.
23.
The bottom of the fuselage, from the front edge of the 1/16" plywood landing
brace, forward to the nose is now sheeted, using the 1/16"x3"x36" balsawood
sheet stock provided in your kit. As shown, this sheeting is applied in cross-grain.
Glue sheeting in place but DO NOT glue the rear edge to the plywood landing
gear brace. Lightly sand the sheeting edges smooth with the fuselage sides.
