The Fish Man spoke thusly: One word. S.P.E.V.

I will second that. I had a SPEV many moon ago. Still have the original Estes parts to build another, plus BMS parts. Someday I will build one and a Thor-Agena B clone.

Still, a 175% SPEV would be, well spevlicious. I may have to play with the ratios tomorrow. Thanks Bill...jeez, I'd like to finish one of the 19 projects in work (seriously).
