PLEASE NOTE: THIS IS NOT AN UPGRADE FIN SET FOR THE ESTES PRO SERIES II OPTIMA RELEASED 12/7/24 AND DOES NOT FIT THAT KIT!!

Estes Optima #2035 Plywood Fin and Ring Set.

This is a set of laser-cut plywood centering rings and fins to scratch build an Estes Optima.  These fins fit a BT-80 tube with a 29mm motor mount.

I have had a lot of requests for this one. The Estes Optima was a really impressive looking rocket that was grossly underpowered on a D motor. These are the main fins and canard fins to scratch build your own, uprated to a 29mm motor. Properly built, this rocket would be capable of some really great flights on motors up to G. These fins fit a BT-80 tube, like the original, but are way stronger.

This is a listing for the fins and rings ONLY. This is not a complete rocket kit.

Thanks for looking.
