D 18. Apply a small bead of thick CA along all previously
glued joints to help reinforce the joints. Be careful though
and don't use more glue than is actually needed.
D 19. Chamfer (slightly round) the ends of the 1/4" x 3-1/
2" Wing Dowels (DOWEL030) and insert them into the holes
near the wing saddle area of the fuselage. DO NOT GLUE
THEM IN UNTIL AFTER COVERING THE FUSELAGE
- This makes it easier to cover!
D 15. Drill a 1/8" dia. hole at both "dots" on former F1A.
Try to drill straight in with the drill perpendicular to the
former.
D 16. Accurately position one of the Die-Cut 1/16" Balsa
Nose Caps (SPECF13) on top of the other Nose Cap so they
are aligned with each other and glue them together with CA.
Glue these to former F1A using thick CA. NOTE: make sure
the nose cap is installed so the motor screw holes are not
covered up. Refer to the cross section view to the right of the
title block on the plans for proper orientation of the nose caps.
D 17. Carve and sand the nose area as shown in the photo.
Sand formers F1A and F1B to achieve a smooth nose but DO
NOT SAND INTO THE CANOPY HOLD DOWN PLATE
- It needs to match up with the canopy later! Sand all edges
of the balsa nose cap to blend nicely with the fuselage. Also
sand all comers of the fuselage to smoothly round them as
shown on cross section views on the plans.
ASSEMBLE THE CANOPY
You'll need the following items:
SPECF06 1/8" Balsa Canopy Base
SPECF05 1/8" Plywood Canopy Front and Back
CANPY045 Clear Canopy
DOWEL035 1/8" X 3/4" Hardwood Dowel
D 1. Trail fit the Die-Cut 1/8" Balsa Canopy Base
(SPECF06) in place on the fuselage. It should be approxi-
mately 1/32" narrower than the fuselage (on both sides) as
shown in the photo. Sand the front and back of the canopy
base at an angle so it will fit the fuselage nicely. Due to
building tolerances, you may also have to sand the sides of the
canopy base slightly to achieve the 1/32" clearance with the
fuselage sides. This allows the canopy to be flush with the
fuselage sides.
D 2. Center the canopy base on the fuselage and tape it in
place with masking tape. Tack glue the Die-Cut 1/8" Ply
