Default Discussion of old model rocketry products

If memory serves, Mike Dorrfler built and flew a smaller version of the Cineroc that fit inside a PNC-55 nose cone. I think it was a Design-of-the-Month winner circa 1974. I don't believe it was ever announced as a product release. However, it is an interesting piece of model rocketry history.

If anyone has any more info on this smaller Cineroc, please post.

Gary Rosenfield made it. Yes, long before Aerotech and even before Composite Dynamics. Do not recall what magazine I saw it in but there was a pic of Gary with it (might have been in Estes' MRN). I think it was more along the lines of a super-modified Cineroc made by an inventive rocketeer, than an actual "prototype" for anything Estes might have made.

Oh..... did not find the magazine, but found two photos, from Friday before NARAM in 2006 when Gary was given a couple of old photos rescued from historical rocket stuff thrown out when an old Estes building was torn down or emptied.

George,

You are right, it was Gary Rosenfeld. The fog lifted from my memory when I read your post. It must have been MRN because that was the only rocketry publication I received back then (I was a in junior high school) and these photos came from Estes. And I remember seeing those two photos you posted. I hope someone can find the article and post it. It was a great accomplishment for the era.

Thanks or posting.

Gary modified an Estes Cineroc to fit in a BT-55 as I recall, so he could do a multi-stage Enerjet flight with fuse delay ignition. U.S. Rockets calls it Discontinuous Staging. I used to give him all my crashed Cineroc parts. The film was fed from randomly stuffed in the lower section to randomly stuffed in the upper section since he did not have spools the right size. Processing film was an entirely at home operation. It was successful.

If you ever go to an event where he is showing his reel of 8mm films, it is worth the trip. I hope he digitizes it someday.

Jerry

The North Coast (by Estes) Dark Star G motor! Estes released the F-62 under the North Coast brand in the 90's and advertised a G motor (G-70 something), but from what I recall, it never made it to market.

I flew a couple of the F-62's and they were nice motors, even if they were deliberately undersized, to fit the undersized motor tubes (28.5 mm) Estes included in the North Coast kits. I always junked the motor tubes so I could use AeroTech reloads.

The F62 was released. IIRC Matt said 6000 were made. The G was never released. It fully existed. I bought several and cut one open. Fancy engineering by Scott Dixon.

He also has a reel taken from the ground with some shocking rocket flights.

Nice Enerjet 2650 flight on this one though!

What did he do to make it "fancy"?
