silicon sealer to the forward area of the tank, where it
exits the fuselage behind the engine mounting box and
to the rear of the tank at the forward bulkhead.
Do not secure the tank into place permanently until after
balancing the airplane. You may need to remove the
tank to mount the battery in the fuel tank compartment.

Slide the fiberglass cowl over the engine and
line up the back edge of the cowl with the marks you
made on the fuselage.

While keeping the back edge of the cowl flush
with the marks, align the front of the cowl with the
crankshaft of the engine. The front of the cowl should
be positioned so the crankshaft is in
nearly
the middle
of the cowl opening. Hold the cowl firmly in place using
pieces of masking tape.
