I have some green Centuri motors dated '73 that also have the gray nozzle clay with graphite, I believe these were made by centuri

I have had/flown several Estes & Centuri 18mm "green" paper motors in the past.
I actually have had MORE 13mm Centuri "long" mini-motors in A4-xM and B4-xM varieties in green than any of the 18mm stuff.
Seem to remember flying some "blue" 13mm Centuri Mini-Motors too, but may be wrong on that one.
Unfortunately I have no intact/unfired or fired "long" Centuri mini-motors any longer.

Roy: are those Rock-A-Chutes the Brown-manufactured ones? or the Estes Enterprise relabled ones? If they are Brown Manifacturing I would love to see a close up of the nozzle with a ruler. Also do they have simple cylinder shaped nozzles or more modern nozzles. Ca

That white German C6-5 is that a WECO?

thanks for the photo!

Estes / Weco

I think Dale Windsor may have a Brown MMI motor.

One way of telling the difference between an Estes made and Centuri made motor is that the Centuri motors used graphite and the angle of the nozzle was different. This info from a very reliable source.

I still do, and all of the B4-xM's are green. ABout half of the A4's are too.

I was under the impression that Centuri never made motors, that they were always made by Estes: under a licensing agreement up until Damon acquired both Estes and Centuri, and then together as the combined company.

Is this not the case? I would be surprised to hear that Centuri started making motors after Estes had been making their motors for years and that they were a combined company.

I know that I have a couple of Estes green motors, and some of the long Centuri mini motors in both blue and green.

Thanks
