Great Planes Spirit 2-Meter Sailplane Kit - GPMA0530 - Manual (Page 7)

D 1. Tape waxed paper over the stabilizer drawing on the
plan. In the same manner as the rudder, cut the 3/16" x 3/8"
balsa pieces and using the die-cut Stab Tips, Stab Center
and Stab Brace from SPRTS01, assemble the stab frame-
work using thin CA glue.
FIN must remain square, do not sand it! Sand the triangle
stock to blend with the leading and trailing edges of the fin.
Also, cut or sand the bottom of the triangle stock to match the
contour of the 3/16" die-cut fin bottom.
* MAXIMUM PERFORMANCE TIP - Sand both sides of
the rudder to a taper as shown on the plans. This requires a
little more work but will help to reduce drag and thus increase
performance of the sailplane.
D 2. Cut the 1/8" x 3/16" "ribs" to length and glue them
in place.
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.
BUILD THE STABILIZER AND ELEVATOR
You'll need the following parts:
SPRTS02 3/16" x 3/8" x 30" Balsa Sticks
SPRTS03 1/8" x 3/16" x 30" Balsa Sticks
SPRTS01 3/16" Die-Cut Tail Parts
SPRTS04 Tapered Elevator
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. Draw a centerline around the stab edges.
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 lips.
