The German company that made motors for Quest went out of business years ago. The Chinese company wanted too much money to continue making motors for Quest.

....so that German company wasn't Klima?
To GH: The Chinese Quest B6s actually outperform their Estes counterparts significantly. It's too bad they are no longer usable in NAR contests.

Thanks, Bob!
Really well told! Thanks. I believe the German motor manufacturer was Weco. One more thing. Bill told me several times what an impediment shipping costs were to bringing in the Chinese motors. Even a huge shipment of motors took up just a tiny fraction of a standard shipping container. It wasn't possible to share a container with non-rocketry items and the fireworks folks were so huge they had no need to share containers. So Quest had to pay for a whole container even though using just a small part of it. I can't recall what percentage of the actual cost of bringing in a pack of motors was due to shipping but I know it was huge. Steve |

I believe it was Weco as well.
We never got the Klima motors here. We are really lucky to still have Estes to be willing to still make BP motors. Still won't stop me from insisting that with modern manufacturing, B14s can't be made in a safer manner than they were in the 60's and early 70's. The return of the C5-3 is a move in the right direction. Having the B8-0 and C5-0 would satisfy me. B6-0s and C6-0s are woefully inadequate boosters.

Bob,
Thanks for the fascinating history. One of these days you should put some of this stuff into a PowerPoint and do a presentation at NARCON!

Steve - thanks.....yeah, Weco. I have a small number of Weco A8-3s that I got when I ordered a bulk package of A6-4s (expecting the Chinese ones) when I first got back into rocketry.
Bob - I agree with Bunny and Steve - a presentation about this would be a fun thing at a NARCON. And I agree with GH about Estes C6-0s in particular. Some current models - the Boosted Bertha being a poster child - can be really sketchy with a C6-0 in the booster. Never mind trying to fly something like a Farside/Farside-X with one. I would love to see C5-0s (and B8-0s and even B8-5s).

I would prefer the B8-0 to the C5-0.
You can have staging occur at an easy recovery altitude.

MRC Tracker motors
I would be intetested in whether anyone has more information on the MRC Tracker motors. I bought about 12 packs on clearance at our Hobby Town around 1990-91, for about $1. The store tag shows $3.65 for a pack of B6-4s, dated 8-28-89. I also have A8-3, B4-4, and C6-5 packs. I have not found much information in my searches.
I remember using a few, and they worked perfectly, but not much recollection beyond that (that was ~30 years ago!). I thought there were no igniters, then noticed two were taped onto one of the motors. To use, the leads were inserted thru the tiny hole in the black plastic “fake nozzle”, the tip dropped into the motor, and then black nozzle was pressed into a small recess in the motor’s nozzle to secure the igniter, and finally the red plastic cap snapped into the black nozzle to hold the leads firmly in place, and separated. Note the glass beads on the igniter hold them separated, and allow spreading of the ends of the leads without concern for the leads near the tip. Quite ingenious.
