Here's a picture of my SMI motors: B18-3 at top, C9-5 below.

Very cool! I'll ask before Terry does. Could you snap a shot of the nozzle end for us?

Seems that Synerjet and Cesaroni figured out the smart way.

I guess AT's logic was that most folks want medium delays, so that's what they pack, but it's whole lot easier to trim a long to a medium than trim a medium to a long

They made more money selling the extra delay.

Is this "Rocket Collector's Journal" something that is still being published?

If not (or even if it is), is there an archive of back issues that is accessible anywhere?

I can provide some information on some of the above.


Brown &Co. Lawrence Brown (Brown Manufacturing/Zenith Fireworks in Missouri) manufactured the 1st commercial Rock-A-Chute motors for MMI. This occured from approx Oct 1957 to January 1959 when Vern Estes sold his first batch of motors to MMI. Some of theseBrown manufactured Rock-A-Chute motors were later sold by Richard Goldsmith of Central Rocket Company.


Rocketflite was I think late 80's very early mid 90's.. they manufactured BP FGH motors first with paper cases that tended to cato due to over pressurization of the paper casings, and solved this later with an outer aluminum tube . They did these BP motor in "sparkies"., called "Silver Streaks". Owned by Greg Dyben... then it became Energon....MRED.

Vulcan was Scott Dixon. Don't know much about his motor history, although I suppose I could write him and ask. ( good idea terry)

The Darkstars were orginally NCR (Chris Johnson/Matt Steel et al) really black smokeies and later Estes?NCR smokies. I had an F62 and and was impressed by its black smoke.

Ravenna Rocket Research R^3 started Late 80's Ravenna OH at the Ravenna ARMY Arsenal. Later became Syner-Jet (or was that Microbrick?) HPR Composites Wayne & Kathy Schaeffer

1/8 AVI were 1/8 ns AVI micro motors mid to late 70's

Pro-Jets were made by Gary Rosenfields et al Composite Dynamics I think late 70's early 80's

US Rockets Jerry Irvine... nuff said

Centuri Super C was the C5... Designed by Ed Brown of Estes for Grant Boyd of Centuri . Centuri wanted/neded a unique motor Had a formed core the core became the B8 core later.

Diamond packs were the old Estes Blue paper containres that was shaped ..somebody post a pic please.. see Rocket planet propulsion auction for some examples

Kosdon... a very big subject... was doing composites at MIT back in the late 1950's early 1960's... was a partner(?)/ business asscociate with Gary Rosenfield and Jerry Irvine at various times....

SynerJet.. was originally R^3 ie Ravenna Rocket Research mid to late 90's

E43 ,F32, F64, G41, G101, H150, H192 Had adjustable delays in 90-91


Mark, if you goto http://groups.google.com/group/rec....ts/topics?hl=en and google on any of the above as keywords you will find a lot of semi-historical information.

Thanks, Terry. Man, I need to catch up!

Back when I was flying rockets in the late '60's, I bought Estes rocket engines in such small quantities (due to my very modest budget) that I don't remember ever seeing them put in any special packaging of their own. A typical order of mine back then might include three motors, all of different impulses. I think that Estes Industries used to just roll them up in newspaper, tape the ends, and then just put them in the box with my kits. I also never saw any motors being sold retail at a shop during that era, although later on, I did see them pretty regularly in stores throughout the 70's and well into the '80's. (But I wasn't buying any motors then, because I wasn't building or flying any rockets at the time.) Until I came fully back to the hobby a few years ago, Estes rocket engines were really the only ones that I had ever seen or heard anything about.
