That's wild!
Even looking at the 3D image up on BARCLONE, it's hard to imagine the fins are supposed to be that wide. It is supposed to fly on a C, right?
Are you trying to get a "one-piece" fin with the grain all running in the same direction? I'd like to make a suggestion: Take a 3/8" wide strip of balsa, same thickness, and cap the tip with the grain running fore-aft. This will help reduce the chances of warping, or "cupping", with such large pieces. It's an old model airplane trick; you'd find it used on elevators and rudders of RC models where the non-moving fin is a single large piece of balsa... |
