WANTED: Scans of the Centuri Magnum Sprint (5356)
OK, I have a Semroc Centuri Magnum Sprint (KV-67), now OOP, and I'm working on a .ork file for it. However, I want to do a comparison between it and the Centuri Magnum Sprint (5356). Problem is: None of the regular sources for instructions have them.
What I do know: According to the description found in 1983 Centuri Catalog)(and the 1982 catalog)(both found on Ninfinger's site), the Magnum Sprint has a plastic nosecone. HOWEVER, the photo doesn't seem to back that up, if the Semroc kit is accurate in its implication (BNC-55AC -> PNC-55AC), but that photo shows a blunter nosecone than the PNC-55AC. What I need... Scans of the instructions, fins, decals (along with a ruler for scale). Photos of an original would also be helpful. Thanks! Jim

The catalog photos look like the PNC-55AC to me. That's the same cone as the later plastic version Goblin, Meteor, Vigilanti etc. By that time, new Centuri stuff was coming out with Estes parts. Sorry, but I don't have documentation.

Looking at the catalog photos, the nosecone seems to be too blunt for a PNC-55AC. That said, the instructions in the Semroc Magnum Sprint (KV-67) mentioned that the rocket was completely built with Estes parts, and directly mentioned that the original used the PNC-55AC. Here's what a stock build of the Semroc Magnum Sprint would look like: Here what it'd look like after swapping in an Estes PNC-55AC: And finally, what it'd look like with an Estes PNC-55AO:

Sorry, got the numbers mixed in my head. The catalog looks like PNC-55AO, which is the Vigilante, Meteor, Goblin, etc. cone.
55AC is the Cherokee nose cone and is pointed.

That makes a lot more sense... Still we've got the disparity between the information contained in the Semroc kit (using a balsa BNC-55AC to replace the PNC-55AC used by Centuri), and the photos in the catalogs which do look a lot like a PNC-55AO.

I've edited in the Ninfinger images from the 1983 catalog... and noticed something else that really casts doubt on the PNC-55AC being used with the Magnum Sprint. If you look at the Magnum Hornet on the same page, it clearly has a PNC-55AC nosecone, and it looks nothing like the Sprint's nosecone.

I had built both the Centuri Magnum Sprint and Magnum Hornet kits back when released in the early 80's. They both had plastic nose cones. The Sprint used the same cone as Vigilante/Skybolt/ Cobra 1500; PNC55AO. The Hornet used the Cherokee-D/Nike-X cone; PNC55AC.
My Sprint POWR-PRANGED on it's second flight in ~1986 due to an offset thrust D11-9. Incidentally, every time I flew a Cherokee-D or Skybolt on a D12-5 or D11-9 I got them back. Every launch on a D12-7 I lost them. 6 Cherokee-D's and 2 Skybolts. Actually got a Cherokee-D back from an old E-kaboom15-8 flight but replaced the idiotic 18" chute with a streamer.

Thanks for the info! It would look like Carl's instructions were inaccurate when it comes to the PNC-55AC then. You wouldn't happen to have the instructions or any photos of it laying about would you?

Have nothing left of the Sprint unfortunately. I remember it mangled the cone.
I think I still have the Hornet somewhere buried in a crate, but that does no good.

If you are still looking, I do have mine. Let me know, and I will take some good pictures of it for you,
