APCP motors get hotter also. Direct contact with plastic might not be such a good thing.

You might be right.

But it has got me to thinking: it wouldn't be to hard to design/fabricate one for the RMS 18. I might have to try that.

Greg

After having handled the samples at NARCON I would agree that as-delivered an 18mm RMS would not work. But a little Dremel or razor saw work on one end might well render something that could work.

I think this is a slick system by John @ Estes. It reminds me of the motor retention device on some plastic rockets that enclose the rear of the motor. This one is just the right amount of material needed to get the job done. Since any melting of the plastic will conform to the expended casing in it, it may never deform enough to be unsuitable. People may replace them anyway as "damaged" out of ignorance or excess of care. Good for business.

As for RMS or other non-standard configuration motors, the simple and time-tested paper conversion mounts with tape or machined thrust rings work just fine. But the ribs on the ID of the Estes 24mm/18mm conversion does make thermal transfer minimal.

RE Maxi-Brutes, John mentioned wanting to bring back the Pershing, hopefully with something other than vaccuum-molded fins. However, they'd need to recreate some parts.

John also mentioned that there is a "24mm black powder motor" in the works.

The tube-cutting guides were really nifty. The table where John was demoing was filled with dozens of sharp-edged little ringlets, cleanly cut by folks wandering by.

Did you mean 29mm or a new and different 24mm?


Bill

I have to say that a lot of what I see coming from Estes is in the right direction, and what's really impressive is that they are doing all of this in the midst of the worst economy we've had in years.

Oh by the way, I'm not here just for the "olde" rocket discussions.

He said 24mm and was not swayed to give more details. He did say "you'll be pleased" but of course that could mean many things to many people......

I broke out my crowbar to try to pry some information out of John but as Benard said from John B." you'll be pleased" and some more kits are in the works but John basicaly gave a no comment.

All in all it's all good news.

Pleased to me would HAVE to mean port/core burning 24mm that can lift some REAL mass for a REALISTIC (i.e. street D12 price) price.
Short of that, I want my B14s back.
If it is say a D30 or D40, now yer tawkin' !
