35. Build the left wing panel.

36. Prepare the wing panels for joining by

cutting a 1/16" wide slot in front of and behind the

spars on W1 as shown in the photo.

39. Measure the distance under the left wing tip

at the bottom of rib W11. If it is 8-3/4" you have

exactly 6 degrees of dihedral in each panel. Don't

be concerned if it is a little off as the dihedral angle

is not at all critical. If it is off by more than 1 /2" you

might want to find out why, but you don't really need

to fix it. When you are satisfied, glue the dihedral

braces to the left wing panel with 30-minute epoxy.

40. Using 3/32" x 3" x 36" balsa, sheet the top

center of the wing from W3 to W3. The strength of

the center section is important so we recommend that

you use aliphatic resin. Note in the photo that we

used one continuous piece across the entire center

section. This greatly increases the strength of the

joint, but it is a bit harder to install this

way.

37. Test fit the 1/16" ply dihedral braces to the

wing panels. Note that the shorter ply brace goes on

the forward side of the spars. When satisfied with

the fit, glue the braces to the right wing panel with

30-minute epoxy. Remove the left panel and clean

off any epoxy that seeped out from the joint.

38. After the epoxy has cured, slide the left panel

back into position. Position the right panel flat on your

building board and prop the left tip off the building

board. Don't you wish your surface was longer!!

1. Cover the right wing panel with wax paper.

Cut the lower LE sheet from a 3/32" x 1/2"

x 24"

balsa stick and pin it to the plan.
