I am building a BT80 WAC Corporal for my L1 attempt. The plan is to launch at the end of July.
For no good reason other than access to a CNC and CAD/CAM software, I've decided to airfoil the fins, and taper them root to edge. The plan is to mill each fin in two halves, then clamshell them together. I was going to used 3/32 aircraft ply. Staring at the model, the razor-edged finished fin is a credible facsimile of the fin on the actual WAC Corporal. It also looks too fragile.
Before I change the design, I'd be glad of any advice on how to toughen up the fins.
I am thinking that wrapping the fins would defeat the purpose of milling it down to a sharp edge. I am wondering if there is something I could sandwich between the clam-shell halves that would support the thin edge?
