Great Planes Super Sportster 40 MkII Kit - GPMA0205 - Manual (Page 7)

Work over the plans, covered with waxed paper, on a flat
work surface. Refer to the plans to identify the parts and
their locations.
D 1. Locate the shaped 1/4" balsa forward and aft stab
parts. Check their fit and sand the mating edges as
needed. Glue the two parts together with a thin bead of
medium CA. Wipe off any excess from the surface before
it cures.
D 2. Locate the shaped 1/4" balsa forward and aft fin
parts. Check their fit and sand the mating edges as
needed. Glue the two parts together with a thin bead of
medium CA. Wipe off any excess from the surface before it
cures.
D 3. Sand the joints of both assemblies smooth with sharp
220-grit sandpaper and a sanding block.
D 4. Tape the two shaped 1/4" balsa elevators in position
on the TE of the stab. Center the bent elevator joiner wire
over the elevators as shown, then mark the location of
the "arms."
D 5. Carefully draw a centerline all around the edges of
both elevators. Drill a 1/8" diameter pilot hole into the LE of
each elevator (on the centerline) at the marked location.
Re-drill the holes with a 9/64" bit. The holes must be at
least 1-1/8" deep.
D 6. Cut a 1/8" deep groove in the elevator LE between
the inside edge and the hole you drilled. Insert the joiner
wire. Adjust the depth of the groove until the joiner wire is
flush with the LE.
D 7. Test fit the joiner wire into both elevators. Make sure
that both elevators are flat on the work surface and that the
tips of the elevators align with the tips of the stab.
D 8. Sand the LE of the elevators to a "V" shape as shown
on the plans. Sand a radius on the LE and tip ends of the
stab and the TE of the elevator. Leave the TE of the stab
squared off.
D 9. Position the shaped 1/4" balsa rudder over the plans.
Align the bent wire tail gear over the bottom end of the
rudder as shown on the plans. Mark the tail gear "arm"
location on the centerline of the rudder LE. Drill a 7/64"
hole 5/8" deep at this spot.
