I know this thread has been dormant for a couple of years now, and I was just wondering if any more progress has been made on this or if motors from Semroc is a totally dead issue? If it is dead, I can completely understand that Carl and crew are putting their energies into producing more and better models. But I would still love to see a few of the low powered motors brought back into production that have not been available for a very long time. At this time, I would love to see the S motors brought back - I know we can use T motors in adapters, but an A10-3T is not the same as an A8-3S in a classic model that was originally designed for the short motors (such as the Midget).
Just out of curiosity, is there enough room in an 18mm short casing for the delay and ejection of an A8-5? And a 1/2A6-4S would be awesome for low power two stagers as well! |

If you use the current Estes thin wall casings (I.D. 0.500"), it is about 1½" from the front of the casing to the front of the clay cap over the ejection charge. Estes did offer A5-0S, A5-2S, and A5-4S motors in the 1970, 1971 (both editions), and 1972 catalogs.

I stuffed some wadding into the end of the motors while I was cutting them to make sure a spark from the sawing process didn't set off the any stray powder. Quote:

No can do - the only place I get to fly is at our club launches, so NAR rules are always in effect (no modified motors). So cutting down a regular motor is not an option. And I thought of using the adapter with a 1/2A3-4T (I have the Semoc Midget that comes with T motor adapter sleeves), but as with using the A10-0 and A10-3T, it adds weight to the motor end of the model that wouldn't be there with an S motor using the current style casings. Granted, not a big deal, but still worth thinking about. Greg |

Regarding your NAR club difficulty (Re: using "cut-down" shorty motors at club launches), I see a niche market for motor, er...re-printing... I'm a NAR member, too, but if one -secretly- breaks a rule that is a "victim-less crime" anyway, I have a hard time working up righteous indignation against violators. To me, it just isn't in the same category as, say, launching rockets at angles of less than 30 degrees to the local vertical, or launching flammable or explosive payloads--those are clearly dangerous activities, while using "cut-down" S motors is a "paper/political" violation. If I were in your situation, I'd keep my own counsel and enjoy some S motor nostalgia flying.

Most of the old motor cases had extra thick walls, similar in thickness to a T motor inserted into a spent case. The mass is fairly close. I've flown stock Midgets using the 18-mm adapted combo of A10-0T to ½A3-4T many times with no stability issues. Doug .

Would also REALLY like to know if we are going to see any sort of Semroc motors in the NEAR future.
I for one would gladly like to see them come out with say half a dozen new motors not on the market (one of which MUST be the B14) soon rather than any new kits. The LPR/MPR market needs new MOTORS far more than kits. They already offer more kits than all the other major LPR/MPR suppliers combined.

Indeed, after accidentally flying a couple of 1/2A6-4's in an Astron Scout at NARAM-50 (didn't realize they were LONG decertified), and finding they were the PERFECT motor for the Scout, I've used adapted 1/2A3-4Ts in it for even better flights.
