This is what I got in the box for the flying surfaces. 1/8" liteply. At first I thought, I've been cheated with crummy useless pieces to make it look like I'm getting more for my money but then I thought about it and figured that it'd be probably faster to put 1/8" balsa on both sides and build up the surfaces. The leading edge on the elevator and rudder would have to be very hard balsa. I'm thinking it'd be easy to get a reasonable facsimile of the welded tailsurfaces of the original. You can see some of my pencil lines where the pieces will go.
I believe a number of builders go this route, but with thin balsa wood for the center portion. Ideas??
