RE: ViperDog Build Thread
I used three pieces of 4" x 1/16" x 48" balsa to make each wing skin.
Just trim parts to fit and tape.
Each skin was later trimmed to about 10 1/2" wide. This leaves a little overhang on both sides of the wing shucks.
Both skins were joined with a piece of masking tape. You leave about 1/8" of gap between the skins to allow for folding.
