2. Cut seven stringers for the front of the turtledeck from
two 1/8" x 1/4" x 36" [3.2 x 6.4 x 910mm] balsa sticks. Glue
the stringers into the notches in the stringers. Sand the ends
of the stringers even with formers FD1 and FD3.
❏
3. Cut half of the front turtledeck sheeting to the
dimensions shown in the sketch from a 3/32" x 3" x 24"
[2.4 x 75 x 610mm] balsa sheet. Wet the outside of the sheet
with a few sprays of window cleaner, then gradually soften
the sheet by bending it as shown.
❏
4. Test fit and bend the sheet into position. Trim the sheet
as necessary so the top edge ends in the middle of the top,
middle stringer. After the sheet has been cut to the correct
size, glue only the bottom edge to the fuselage.
❏
5. Apply medium or thick CA to the stringers and formers,
then bend the sheet down into position. Hold tightly for a few
seconds until the CA has hardened enough to hold on its own.
❏
6. Cut, wet, bend, then glue the other half of the turtledeck
sheeting into position. Sand the ends of the sheeting even
with the formers. Add balsa filler if necessary, allow to dry,
then sand smooth.

1. Glue the stab saddle (SS) into position.
