Each of the 4 wings has a front and rear spar made of 1.5 x .058 60601T6 aluminum tube. Some 32 fittings are needed to hold it all together and they took almost as long to build as the fuselage.

Get yourself some 2x8's, angle iron, 4130 strap and 230 lbs. of aviator wannabe and you can make yourself a real nice tension tester. Butt crack is optional.
Close up of 2 fittings riveted to scrap spar material and ready for testing. 230 lbs. at the end equals 1440 lbs. tension at the fitting. And they said those extra trips to the pizza buffet weren't doing anyone any good.
Clecoed wing ready for riveting.
The trailing edge is cut out of a Home Depot aluminum gutter (please don't tell my mom). Only $3.95 for a 10 ft 3003 .020 gutter. Cut the 90 degree bend out of the back of it and bend it over for a nice straight trailing edge. Frank Wilson helped put the fabric crimp in using some angle iron and 2 by 4's. Of course, if you have a 10-ft brake this is all academic.
