16. Prepare the 1/4" x 3/4" LE that you

installed in step 11 for sheeting. Carve and sand the

LE to blend with the tops of the ribs. Use masking

tape on the ribs so that you don't alter their shape.

17. Glue the leading edge skin that you

prepared in step 2 to the top spar, ribs and LE using

aliphatic resin.

18. After the glue has fully dried,

remove the

wing from the building board.

19. Carve and sand the TE and LE to blend

with the bottom of the ribs as you did in steps 14

and 16.

20. Trim the LE and TE sheeting and the spars

even with ribs W1 and W11.

23. Fit and glue the 1/8" die-cut ply webs to

the front of the landing gear rail using 30-minute

epoxy. The webs should fit tightly between the ribs,

sheeting and landing gear rail.

24. Using a 1 /4" bit, drill a hole through the

landing gear block into the stub block. Radius the

top of the hole to fit the bend in the 1 /4" landing

gear wire.

25. Using the 5/8" x 2" x 8" balsa block, cut

and fit the TE filler block between W1 and W2. Glue

the block into place with medium CA. Carve and

sand the block to the contour of the ribs.

21. Glue the landing gear stub block to W2

using 30-minute epoxy. The block fits into the long

cutout in the 1 /8" ply doubler.

22. Check the fit of the landing gear block in

ribs W2, W3 and W4. When satisfied with the fit,

glue it in place with 30-minute epoxy.

26. Prepare the trailing edge for sheeting.

Taper the trailing edge of the 3/32" x 3" sheet that

was installed in step 12 to blend with the contour of

the ribs from W1 to W6. Use a 3/32" x 3" x 24"

sheet to sheet the top of the trailing edge. Trim the

sheet to fit the 3/32" x 15/16" sheet installed in step

15. Glue the sheet in place with aliphatic resin. Use a

long T-bar sander and weights to align the ribs and

hold the rear of the wing flat to the building board.
