But, that's a thought if someone was willing to try it -- a laser-cut set of matteboard fins, 0.02" thick. Carl's material is far superior to what Estes used in the past, so it might hold up longer once it's been sealed and painted.

I heartily agree! Structurally, the long-chord, short-span, right-triangular A.S.P. fin is probably the strongest possible fin planform for use with *any* kind of fin material, so such "fibre" fins should hold up very well. If Carl brings out an A.S.P. kit (either Deci-Scale or a reproduction of the BT-20 size Estes A.S.P.), I would have absolutely no objections to fibre fins in the kit. |
