phil, i think i have broken off each spruce stringer at least once now! the plywood piece and "rollcage" are next so hopefully that will help like you say. i have some limited experience at soldering and i have some friends who can help me if i goon that up.

as far as an operating door, i think i will give that a go. again, i don't think i'll be flying this one but an operating door will still look good.
