of the struts equals an approximately one degree change in
incidence.
❏
12. Mark the exact center of the aft support where the
wing bolt hole will be drilled.
❏
13. Use a #7 drill to drill a hole through the center of the
aft strut. Use a 1/4-20 tap to cut threads into the hole.
❏
14. Place the wing on the struts. Bolt the wing to the aft
strut with a 1/4-20 nylon wing bolt (you may cut the bolt to a
length of 1-1/8"), but do not tighten the bolt all the way.
❏
15. Measure the distance between both wing tips and the
end of the fuse. Rotate the wing about the aft wing bolt until
the distances are equal and the wing is centered as
indicated by "A" = "A" in the sketch.
❏
16. Once you have achieved the correct alignment, hold
the wing in position and drill #7 holes through the forward
supports using the holes in the wing as a guide. Tap 1/4-20
threads into the support. Add a few drops of thin CA to the
holes in both supports and allow to fully harden. Re-tap the
threads.
❏
17. Before bolting the wing into position, cut two 10" cross
braces from the 3/16" x 3/8" x 20" basswood stick. Hold one
of the cross braces up to the main wing struts, then mark
where it is to be cut to fit between the struts as shown on
the plan.
❏
18. Mark the other cross brace for the other side of the
struts the same way.
❏
19. Mount the wing to the supports. Cut the cross braces
where you marked them. Test fit the cross braces between
the struts to make sure they fit well. Make adjustments
where necessary. The cross braces will be glued to the main
wing struts after the fuselage has been covered and the
main wing struts have been glued into position.
❏
20. Round the corners of the cross braces just the same
as you did for the main wing struts.
❏
21. Cut the hole in the bottom of the center-section where
shown on the plan for the aileron servo wires.
