Wanted: 18mm Aerotech E reloads
I'm interested in acquiring some vintage RMS 18/20 "baby" E loads.
PM me if you have any willing to part with. |
Anyone have any ?

I wasn't aware of E reloads for the 18/20. I seem to remember B and C quite awhile back. When I bought my first 18/20 RMS I only saw D13 and D24 available. |
The only E reload for the RMS-18/10 was the E27-4T. It had a total impulse of 23 Newton-seconds. Unfortunately, there is not enough room in the case for a longer delay column. The motor worked well on the heavier 1.9" Aerotech kits. Since these reloads have not been manufactured since the early 1990s, you are likely to get a bonus delay if you don't swap the old delay for a new one. I believe these reloads used the same delay as the D24-4, but they were discontinued long before Aerotech released the Hobby Delay Kits (HDKs) for the hobby-line RMS motors.

Aerotech made a
B6-Blue Thunder C4-White Lightning, grain slotted at a shallow angle to produce a moon burner profile C6-White Lightning C12-Blue Thunder The current D13 and D24 And the mentioned E27 It’s cool AT added the glider motors C3.4, D2.3 for The case, |

Wow, B through E in that one case. Too bad they weren't profitable. |
Unfortunately now all we can barely get are 20n-sec D's.
Would really like that "Baby E" option for my Mars Lander. The B's and C's are pretty much covered by Q-Jets. |

I know far more about that whole product line at AeroTech than I care to remember. ...And now, another episode of "Bob's wacky history of model rocketry products". When the model rocketry line of RMS products was developed at AeroTech in early 1992, the RMS-18 motor casing was just going to have a 'D' performance load for it. This became the D13 load. (On another tangent, when the RMS-18 load was determined to be a 'D13', Dan Meyer took a picture of the RMS-18 casing and faxed it to then-NAR President Pat Miller with a note that basically said, "Be afraid. Be very afraid.") So the D13 would be the load for the RMS-18 casing and that was that. I couldn't leave it alone. "What's the largest impulse load we can fit in the case," I asked? Quickly followed up with, "Can we put smaller loads in the case?" That got some people thinking. TBC... |
Oh....I have a feeling I’m going to enjoy this story.... :)

Me too....
