4. Glue a ¼ x ¼ balsa spar to W15 Ply spar, aligning
with the bottom edge. For the left side, the balsa spar
will glue to the front of W15.
5. Slide W1 into the center slot in W15. Temporarily
slide the other W1 into the slot as well, but do not
glue. Glue only the left side W1 in place.
6. Align and glue W2, W3, W4, W5, and W6 in place.
7. Glue W7, W8, and W9 in place. Use slight upward
pressure on the balsa spar to fully seat it in the rib
while gluing.
8. Bevel the side of W9A to fit and glue in place.
9. Glue W16 and W17 in place in the notches in the
trailing edges of the ribs.
10. Glue W10 in place.
11. If using the single servo aileron setup, do the follow-
ing: Locate and drill the hole for the bellcrank bolt in
W19. Install the bellcrank on W19. Cut the plastic
pushrod housing to 18 1/2” and slide the housing
through the holes in the ribs to W10. Open up the
holes at W10 and W2 slightly to allow for pushrod
movement and glue the housing to all the ribs
except W10 and W2. Install W19 with the bellcrank
side down, and glue W11 in place. Cut two inner
pushrods to 20”, assemble them with the aileron
connector, and slide the pushrod through the hous-
ing. Cut the pushrod at the bellcrank to allow for the
clevis, install the clevis, and connect to the bell-
crank.
12. Glue W12, W13, and W14 in place.
13. Cut a piece of ¼ x ¾ balsa stock to length and glue
to W9 thru W14 as the aileron spar.
