13. Unpin the assembly from the board and turn it over.
Cut the bottom balsa spars from ¼ x ¼ stock and
glue in place.
14. Cut the Maple Gear Blocks to size and epoxy into
the slots in W2, W3 and W4. Relieve the slots as
necessary to allow the gear block to fit flush.
15. Epoxy the Maple Gear Block Anchors to the gear
blocks and W2A.
16. Add tri-stock to the sides of the gear blocks for sup-
port.
17. If you plan to add functional flaps, drill a hole in
W19 at the “+” and slide W19 into the slots in W3
and W4. Align flush with the edge of W4.
18. Install bellcranks to W19 (on the bottom), with the
“L” facing outward. Add the pushrods for the servo
linkage.
6. Slide W22 Ply Servo Tray into the slots in W1 and
W2. Slide W3s in place and pin to the board.
7. Slide W4s (with W4Bs facing inward) in place and
pin to the board.
8. Glue all the pieces at this time. Add tri-stock to the
corners of W13 and W14 and W2 and W4.
9. Glue W15 to the trailing edges of W1 and W2.
10. Glue W16 to the trailing edges of W3 and W4,
11. Cut the balsa spars from ¼ x ¼ stock, and
glue in place. Add ¼ x ¼ spacers to W22
for the servos to mount to. Add the mounts
for the flaps on top of W22, and the
mounts for the ailerons on the bottom of
W22.
Note: The spar in this case is not for structural strength, it’s
for attachment of other pieces.
12. Cut the leading edge pieces from 3/8 x 1
x 18 balsa stock, and glue in place. Glue
the center piece first, followed by the
outer pieces. Leave at least 1/16” overlap
of the leading edge with the ribs for the
sheeting to but against.
