Great Planes SlowPoke Sport 40 Kit - GPMA0492 - Manual (Page 7)

Work on a flat surface over the plan covered with wax paper
or Great Planes Plan Protector. Refer to the plan and
die-cut patterns on pages 4 and 5 to identify and position
the parts.
❏ 1. Locate two each of the 1/8" die-cut balsa rudder top
(RT), the two piece rudder trailing edge (RTE) and the
rudder base (RB) and glue each of the pairs together,
carefully aligning the pieces for a flush fit. Sand off any
irregularities or excess glue.
❏ 2. Using a 1/4" x 1/2" x 30" balsa stick, measure and cut
the two rudder leading edge sticks to match the plan. Glue
these two pieces together over the plan and pin them in
place. Test fit, then glue the RT, RTE and RB in position. Be
sure that all parts are aligned over the plan.
❏
3. Using a 1/4" x 1/4" x 24" balsa stick, measure, cut and
glue all cross bracing for the rudder in position. Remove
the pins and sand both sides of the rudder smooth.
❏
4. Measure and cut the leftover 1/4" x 1/2" balsa stick
from the rudder to start framing the fin to match the plan.
Use additional 1/4" x 1/2" x 30" balsa as required. When
satisfied with the fit, glue the pieces together and pin them
to the board. Using a 1/4" x 1/4" x 24" balsa stick, measure,
cut and glue all cross bracing for the fin in position.
Remove the pins and sand both sides of the fin smooth.
❏
5. Draw a centerline on the leading edge of the rudder.
Sand the leading edge of the rudder to a “V” shape as
shown on the plan. Sand a radius on the leading edge of the
fin and the trailing edge of the rudder.
Hint: A Great Planes Easy-Touch Multi Sander makes both
of these sanding jobs a snap!
