Bump...

My collection includes a vintage Centuri V-2 (circa 1971). It was built by my 9th grade band teacher. I bought it and his Centuri Saturn V as well as his 1971 catalogs back in 1983.

My model was launched many times by me, and I suspect even more times by him.

My model exactly matches the 1971 Centuri model and the JimZ instructions I've seen as best as I can tell. From my examination of the rocket, I can see no indication that it was shortened, or altered in any way (save for the very tip of the nosecone which was munched at some time. The original shock cord mount was apparently a ring glued inside the body tube. However it was replaced at some time by him (with a replica of the Estes tri-fold teabag), and the rubber band shock cord was replaced by elastic cord. The parachute appears to be original. It has white ink printed on a transparent red(ish)/pink plastic sheet. and was built with red lines. The parachute says "Centuri Engineering Company Phoenix Arizona".

The paint scheme doesn't match any of the three versions seen on the instructions found on JimZ's website.



My fins are 3/32" thick.

Here's the numbers that I have from my kit, and how they stack up...

5.75" Exposed Nosecone
4.00" Body Tube
3.50" Exposed Tail Cone [EDIT] Corrected... see next post[/EDIT]
.875" Fins (below tail cone)
14.125" Total length (as is)

14.20" Length from 1971 Centuri Catalog.

I know that my numbers don't match up with Gord's, but it wouldn't be unheard of for a rocket manufacturer to change body tube lengths or nosecones at some time during production (e.g.: Estes Cherokee D).

For more on my methods of measuring you can visit this thread.

Try rotating your nose cone 90 degrees.

I hate to say it but your measurements add up to 15.125. Did you maybe "cut an inch" on the ruler and your tailcone is 3.5"?

It looks to be shorter than the tube.

I kept the rocket the way that I received it from my teacher all those years ago... It never crossed my mind that it wasn't supposed to be that way.

Corrected the tail cone. You're right, I accidentally added an inch to it somehow... I've hunted it down and corrected it where I mis-typed.

Oops! I should have said 180 degrees. No wonder they put erasers on pencils,anyone can make a mistake.
