I know that for me , buying Centuri kits was a matter of LHS supply, in the mid 70's my local store had more of a supply of Estes kits with a Centuri kit MAYBE sitting in the display. I've been shopping there for over 30 years and got to be friendly with the owner, and she asked me if I wanted and of the old rocket stuff sitting in the drawers behind the counter. BOY was I surprised to get a bunch of old Centuri parts! I was very surprised, but she mentioned that they used to get quite a few centuri items in, but they must have sold before I got to see any. Thankfully Semroc offers sizes of body tubes they used in Centuri kits, Now I just have to print of the plans and start building...

I know for me, finding a Centuri kit in a local hobby shop was all but impossible in the mid-seventies. The only two I ever built were the Nike-Smoke (which I still have) and the Starfire ((I wish I still had) , both of which my dad brought back from business trips. I was able to fill out the form in the back of Boy's Life and get a catalog but that was about it. I remember wanting a Little Joe and a Black Widow.

Some day I want to rob enough 7-11s to have Sandman turn me an up-scale nosecone for a Super Starfire. That kit was always my favorite 3FNC . . .

The only time there was a conflict between Estes and Centuri equipment was if you tried to launch a (Centuri) Point off an Estes launcher!
There is a name for it (can't think of it right now) but there was actually a "vacuum" that would form between the Estes round deflector and the round base of the Point. The Centuri deflectors were not flat, but angled away from the rod.
My Point sat on the launcher an burned! The Semroc instructions say to raise it 10-12" above the blast deflector.
Back before I knew the history, I wondered if the Estes and Centuri engines came from the same factory. They were identical except for the printing on the outside wrap.

Build it, watch it fly - and wonder why!

That would be the Krushnik (sp?) Effect.

That's it! I knew it was a cross between (something like) "Smashing and Sputnik".
Thanks, I'll sleep tonight.
