D 2 After the epoxy cures, install the top and bottom wings
on the fuselage
D 1. Place the canopy on the fuselage in the location
shown on the plan, then temporarily hold it in position
with tape.
D 2 Use a felt-tip pen to accurately trace the canopy
outline onto the covering Remove the canopy Use a sharp
#11 blade to carefully cut away about a 1/32" wide strip of
covering inside the line you marked without cutting into
the balsa Wipe away the ink line with a paper towel lightly
dampened with alcohol
D 3 Before permanently installing the canopy, securely
glue your pilot in place For the most security, in addition to
glue, screw the base of the pilot to the cockpit floor with two
#4 or #6 sheet metal screws from the underside of the
cockpit floor Place the instrument panel decal on the
instrument panel
D 3 Cut the six 3/4" x 12" hardwood struts to the shape
shown on the fuselage plan Use a sanding bar loaded with
150-grit sandpaper to round the tips to the desired shape The
struts can be covered with MonoKote film covering or painted
with a fuelproof paint such as LustreKote spray paint
D 4. Reposition the canopy on the fuselage and confirm
that it covers the exposed wood Glue the canopy to the
fuselage using masking tape to hold it in position until the
glue dries We recommend a glue specifically formulated
for gluing on canopies such as Pacer Formula 560
canopy glue Formula 560 is like regular white glue
(aliphatic resin) in that it dries clear and cleans-up with
water but bonds extremely well to butyrate and dries
overnight (to allow for accurate positioning).
D 4 Use a 5/64" drill bit to drill a hole 1/2" deep, centered
in the notch, at both ends of the struts
Hint: To drill a hole 1/2" deep, wrap a piece of masking
tape around the drill bit 1/2" from the point Drill into the
wood until the masking tape touches the wood Drill holes
in both ends of all six struts.
D 1 Use 30-minute epoxy to glue the eight strut tabs, you
assembled before building the wings, into the slots in the
top of the bottom wing and the bottom of the top wing.
D 5 Thread the six 4-40 nuts close to the head of six of
the 4-40 x 1" machine screws Mix a small amount of
30-minute epoxy and apply a small amount to the last 1/2"
of threads on the machine screws Then thread the
machine screw halfway into one end of each strut Install
only the six machine screws with the nuts installed.
