WING SEPARATION FEATURE
11. Place your “Spar Brace” in place against the bottom spar. Wedge in place. Be
sure the centerline on your “Spar Brace” is lined up with W-1. (Note: If you want
a one piece wing, glue the “spar brace” to the bottom spar.)
12. Cut the mid spar pieces 3/8” x 3/4” stock to 3-7/8” long. Place against the top of
“Spar Brace” and against the front shear web. Apply a small amount of thick
C.A. to each end where it touches theW-5 and W-6 ribs. When set remove the
“Spar Brace” to insure that the glue did not contact the “Brace.”
13. Reinstall spar brace and repeat above until all mid spar pieces are in place. Note:
The piece between W-1 and W-2 has to be shaped in order to fit in place.
14. Remove spar brace. Thoroughly glue (C.A.) all mid spar pieces to the front web
and ribs.
15. Now install the shear webs to the back of the main spar. Use thick C.A. and not
so much that it runs inside of cavity.
16. Watch for glue running into “Spar Brace” cavity. Remove any globs.
17. Install the spar brace and check fit. It must enter to a depth of the centerline. Did
you put the proper left-right side into the wing when doing the mid spar
assembly? If not, change the designation (reverse the left right).
18. Install the “G.P.” (Gear Plate) and two “G.B.” (Gear Blocks) to W-5, 6, & 7.
Install 1/4” thick by 3/8” balsa to top and bottom of “G.P.” at W-5 & 7.
19. Install the “Wing Tongue” to front of W-1-2. Use 30 Minute Epoxy.
20. Pin the 1/8” L.E.-2 to front of ribs with the top edge even with the top front of the
ribs. Use your straight edge to check for ribs that are too long. Trim. Glue in
place. Sand to an angle that part of L.E.-2, which flows into rib contour.
21. Install the W.P.B. 1/8” ply part between W-1 and W-2 behind the flap header.
Install the 1/8” balsa F.H.-2 to F.H.-1. This part ends flush with top of ribs (see
plans).
22. Your retracts should be installed now if you are going to use bolts and blind nuts.
If you plan on using sheet metal screws you may proceed. The flap actuators are
also installed NOW!
23. Make up 4 “A”-“B” wing sheet parts. Glue the “B”s to the “A”s. (You will have
to add on a 1”extension to the “A” and “C” sheets.) (Do this to the tip end.)
