I'm up scaling a Estes Crossbow SST, from BT-20 to BT-60 and was wondering about how to upscale the fin guide since it has five fins in an unusual arrangement. Just take the measurements and times them up, or is there an easier way with software?
Edit: I thought I'd add that I've scanned the wrap in, so its on a computer.
