Chapter 24
Wing Assembly
This chapter will cover the assembly of the wing. If you wish, you may do this work
simultaneously with the work covered in Chapter 25 “Fuselage, Preliminary Assembly”.
Kits on Hand
To do the work covered in this chapter, you should have the following:
Kit No. 804 Flap Controls & Equipment
We also suggest that you purchase the wing tip lenses and the strobe system at this time.
You will also need additional spruce for blocking and plywood for skinning the wing. We suggest
that you order enough spruce for the fuselage and enough plywood to skin the fuselage.
Wing Assembly Jig
The wing assembly jig consists of three jigs: a fuselage centerboard, a template for wing Sta. 1 and
a template for wing Sta. 14. The use of these jigs will become clear to you as we discuss the
assembly of the wing, so it might be a good idea to read this entire chapter before making the jigs.
The fuselage centerboard (see Figure 1) is made of 1” or 3/4” plywood. It is essential that the jig
be constructed accurately and that all lines be drawn perpendicular to W.L. 0. Lay out the
centerboard, but do not cut the four slots until after the two braces are made and installed.
The centerboard has two braces which are made of the same 1” or 3/4” plywood. Cut two pieces
of plywood to 100mm by 1300mm and install with bolts as shown on Figure 2. The centerboard
will be weakened when the slots are cut, and by installing the braces first the bolts keep the
centerboard from distorting.
Remove the braces and cut the slots. The two rectangular holes are for the flap torque tube and
control stick assembly. Trial fit the fuselage centerboard to each fuselage frame (and each wing
spar) that will be installed in the jig.
