[Wanted] Estes Shadow/Optima Fin Patterns
I've found JimZ's scans, but w/o a scale, the printout is dubious. I've found a .rkt file on rocketreviews, but if the fin placement is "right" the fins are too large (backed up by my printout of JimZ's pattern). I've found so many errors in .rkt files from there, I always try to double check the info found there.
Anyone got a set they can scan w/a ruler so I can get accurate info? Thanks! Jim

The root edge of both fin sets is 5". The main fin is 5" across at the widest point. The forward fins set is 1" wide at its widest point. The balsa is 1/8" thick. Note that these measurements were taken from a built model. Hope this helps.
