Great Planes ElectroStreak Sailplane Kit - GPMA0385 - Manual (Page 25)

D 6. Holding the wing firmly in its correct position,
drill a 5/32" hole down through the wing and plywood wing
plate. Try to hold the drill perpendicular to the top surface
of the wing, as shown on the plan.
D 7. Remove the wing from the fuselage and re-drill
the hole in the wing only, using a 13/64 (or 7/32") drill.
Apply thin CA to the inside of this hole (to harden the balsa),
the re-drill the hole after the glue has fully hardened.
D 8. Use a 10-24 tap to cut threads in the hole in the
plywood wing plate. Apply thin CA to the threads to harden
them, then re-tap the threads after the glue has fully hard-
ened.
INSTALL WING FAIRING
block to fit the top of the wing.
D 3. Round the comers of the block to match the
fuselage.
D 4. Tack glue the fairing block in place with a couple
drops of CA. NOTE: Do not glue the wing to the saddle!
D 5. Remove the wing from the fuse, and securely glue
the fairing block to the wing. You may then use some light-
weight balsa filler compound to fill any gaps and irregulari-
ties.
INSTALL AILERONS
NOTE; The ailerons are sawn (but not sanded), so you'll have to
sand off the saw marks using a T-bar with 80 or 100-grit sandpaper,
for a nice smooth finish.
D 1. Trim the ailerons to the length shown on the plan.
D 2. Draw a centerline on the leading edge of the
ailerons and the trailing edge of the wing.
D 3. Sand the leading edge of the ailerons to a "V"-
shape, as shown on the "WING CROSS-SECTION ATW-
1". Sand the trailing edge of the ailerons to a rounded shape.
D 4. Lay the wing on the plan and mark the hinge
locations on the wing TE.
10-24 NYLON BOLT
D 1. Place the wing in the saddle and install the 10-24
nylon bolt. (The heavy paper shim should be in place on the
saddle to simulate the foam wing seating tape).
D 2. Carve and sand the 3/8" x 2-3/8" x 2-3/8" balsa
D 5. Hold the ailerons against the TE, and transfer the
hinge marks over to the ailerons.
