RE: Berkeley B 26
Here's some build pics!! All formers are hand cut with a knife. The "spars" on the sides of the fuse are spruce, but everything else is balsa. The plans look like they call for 1/8" ply formers, but I used 3/32" balsa. Total build time shown is 9-9.5 hours.
Edit: BTW, the fuse IS straight. the floor isn't.
