Question Estes Pro Series Jayhawk vs Centuri Magnum Jayhawk?

Unfortunately from this computer, I'm not able to see the .tif file found on the Old Rocket Plans site.

I get the impression that the Estes Pro Series Jayhawk was a reissue of the older Centuri Magnum Jayhawk, that only had updated (read vacuform/plastic) parts. Is this correct?

I've got the Estes Jayhawk, and to be honest, I botched it. Not so bad as it couldn't be finished, just not so good IMHO it'd fly well (if at all).

Now I've got a replacement body tube (and a spare authentic NC too), and I'd like to make both, one a display only, the other capable of flight (perhaps on a 29mm motor).

Since I didn't use the vacuform parts, I could try to copy those, OR if the Magnum Jayhawk is the same scale go old school w/tube and card (my preference (less $$$)).

Thanks!
JIm

They aren't the same. I'm sure someone else will chime in here before I can dig up the details, but it wasn't a reissue.

No, they aren't. A few differences - Estes Pro Series has through the wall fins. Antenna mounts are on the nose cone, and in line with the wings, which is wrong. Estes is 2.5" body tube. Centuri is 2.6", no through the wall fins, scratch build belly conduit, antenna mounts and pitot tube (missing from Estes). Centuri is a little bit longer, Estes a little bit stronger built. I have both in the queue. Estes did use the same drawings for decal placement as the Centuri kit, but they are pretty different. I know this is necromancing a thread, but I have both here and I can do a side by side layout if you would like, K'Tesh.

I built the Centuri kit in the fall of 1980, not too long after it was released. It was a fun and challenging build at the time and turned out a nice model. Still have it. I never bought the Estes version but had understood there were at least some differences between them.

If your thick-skinned enough to take a jab for resurrecting a ten your old thread...

Would like, despite the serious breech of etiquette.
