FINISH THE WINDSHIELD
AND COWL
❏ 1. Trim the windshield along the cut-lines and
test fit it to the cabin. Trim where necessary for a
good fit. Tack glue the windshield in place. Note:
The windshield will be permanently attached to the
fuse after the model is covered.
❏ 2. Mount the wing to the fuse. Using a 3/8" x 3"
x 7-1/2" balsa sheet, fit and glue the wing root filler
blocks to ribs W2A, leaving a 1/16" gap between
the windshield and the filler blocks.
❏ 3. Remove the wing and sand the filler blocks to
the shape of the airfoil.
❏ 4. Mount your engine to the fuselage.
❏ 5. Round the bottom corners of the fuselage
sides to match the cowl shape as shown on the plans.
❏ 6. Trim the three cowl sections along the trim
lines. Tape the rear top and rear bottom sections
together with masking tape. Tape the front section
to the two rear halves and test fit it over the front of
the fuse. After all the fitting is done, glue all joints
with thin CA.
❏ 7. Cut the holes in the cowl for the engine,
carburetor, air inlets and air exit. If you go slowly
and remove a little material each time, you will be
rewarded with a tight-fitting and good-looking cowl.
❏ 8. Mount the cowl with four #6 x 1/2" sheet metal
screws and washers. Reinforce seams inside the
cowl and the mounting holes with 1" wide fiberglass
cloth.
❏ 9. Fill the joints with Bondo or a similar filler.
Sand smooth.
❏ 10. Mount the tail gear to the fuse with three #4
x 1/2" sheet metal screws. Drill a hole in the
leading edge of the rudder for the tail gear wire.
