Bob Mathison put this together. The wing is about 135 square inches. Fuselage is 13 1/4 inches long. Wing is 1 inch thick at high point and has a 4 1/2 cord sans flaps with a 24" span not including wing tips.
The leading edge is made up from 3/16 square balsa and sanded to form the curved leading edge. The trailing edge is is 1/4 inch balsa and is tapered to fit the 3/16" flaps.
The fuselage is 1/4 inch balsa with a front end made from 1/4" plywood. The ply is shown in red in the diagram.
The plane was designed for use with a cox baby bee. If a golden bee or black widow is to be used the fuse front end should be shortened by 1/4".
The model was designed to be used as a trainer for my triplet grand children, hence the rugged construction.
Bob and I plan to modify the front end for use with cox production engines and the big mig .049. I've been ill for the past year and I thank bob for his help in completing the first one. The wing tips, vertical stab and canopy were left to the builder.
If the thing flys I will publish a set of plans and offer them here for free.
Edited to add that there are 1/32" inch ply doublers on each side that run from the fire wall to the back of the wing. Remember I built it to be rugged. LOL
