Has anyone publicly documented the core diameters, lengths, and draft angles for the various versions, so some day in the future these motors can be duplicated and re-released by some motivated guy with a mini-Mabel in his barn?
There are guys making Polaroid film again. It could happen. Jerry |

I did an inventory of old motors, and found a number of B14s -- both Estes and Centuri, from 1969 and 1970. I thought I'd made a mistake logging the inventory, and having an entry for a B14-6. I guess I didn't realize there were three variations, with only 1 second difference in delay. All are just loosely bagged, but have been in my basement since the early 80s, so I'm pretty confident these could be OK, and plan to test a B14-0 soon.
The Centuri motors I bought were boxed, and have date code J, which should be 1979, assuming these are Estes-manufactured. My 1969 Estes and Centuri motors have identical "inkings", and differ only in company name and address. I got these boxed motors as seen here, included in the orange, white, and blue display box that contained the smaller, similarly colored 3-packs. I was fortunate to get 2 boxes of B14-0, and 1 box of C5-3S, would have loved to stumble on a full box. Some pics:

Back around 2000 there was an online hobby store, I don't recall the name, that had come across a huge stash of NOS Centuri motors. The majority of them were in the old orange/black/white boxes. One of the motor types they had were B14-6 motors. Amazingly, they were selling these old motors extremely cheap. I bought a ton of motors from them at the time and still have them sitting in storage. I believe they got their motors from the same warehouse where John Boren got his stash of cases of old Centuri motors. Addendum: Now that I think about it I believe it was A2Z Hobbies that had the old motors.

As Scott mentioned, one of the best rockets to use the B14-7 in single-stage is the Astron Sprint. I have probably used that engine in the Sprint more than any other. I often used it in the top stage of my Astron Avenger and my Comanche 3.

Many years ago, when I started flying rockets, around 1970, I really liked two stage rockets. Back then you could get boosters in A, B, C and even shorties. The sight and sound of the staging was really cool. I had a rather large (for Estes) two stage rocket that would stage around 100 feet or more when the first stage was a C engine. When a B14-0 was used it really zipped off the pad and staged just past the launch rod!
I am looking to pick up a two stage model with a motor combination that will not fly out of sight. |

About the closest you can come to the B14 today is the 24mm C11-0. If you can find them. There are a few left out there. The TARC teams loved those motors but Estes stopped making them. maybe the new guys will bring the C11-0 back.
