Great Planes Spectra Electric Sailplane Kit - GPMA0540 - Manual (Page 8)

D 5. Tape the elevator to the stab using masking tape and
sand the leading edge of the stab, the stab tips and the elevator
tips to a smooth rounded shape. The tips of the elevator
should blend in nicely with the stab tips.
D 1. Tape waxed paper over the stabilizer drawing on
the plan so you don't glue the parts to the plan. Using the plan
as a guide, cut the 3/16" x 3/8" balsa pieces from SPRTS02.
Punch out the die-cut Stab Tips, Stab Center and Stab
Brace from SPRTS01 and sand the edges if necessary to
remove any "fuzz''. Assemble the stab framework by pinning
everything in place on the plan. Glue the parts together using
thin CA glue.
D 2. Cut and sand the 1/8" x 3/16" "ribs" (from
SPRTS03) to length and glue them in place. NOTE: It is not
necessary to get these ribs in the exact position shown on the
plan.
D 6. Remove the elevator and draw a center line down its
leading edge. Use your sanding block to sand the same V-
shape as you did on the rudder. The trailing edge should also
be sanded to a smooth rounded shape. Apply thin CA the the
tips of the elevator to harden the wood, and help protect it
from damage.
CUT THE HINGE SLOTS (Do not glue)
NOTE: One-piece molded polypropylene hinges are supplied
in this kit. We have tested many different hinges and have
found that these hinges are one of the best available. We
recommend that you use these hinges and follow the instructions
below to install them. If you choose to use these hinges or the
"pinned"-type hinges, you should cut the hinge slots at this
time. However, if you choose to use the one-piece hinges that
are paper covered for CA glue installation, you may wait until
after covering before cutting the hinge slots.
D 3. Pin or tape the elevator (SPRTS04) in place behind
the stab and use your razor saw to cut the ends off to match the
stab. Sand the the two front comers of the stab to round them
off.
D 4. Remove the stab from the plan and examine it for
any open or bad joints. Fill any gaps with thick CA, then use
your sanding block with medium grit sandpaper to sand both
sides smooth. Carefully draw a centerline around the edges
of the stab (this will help maintain symmetry when sanding).
D 1. Lay the rudder and elevators on the plan and mark
the hinge locations. Place the rudder against the fin TE and
transfer the marks over to the fin. Place the elevator against
the stab TE and transfer the marks over to the stab.
