When I got that all I had to do was log in into my Semroc account in another tab of my browser (which gave me the "welcome back" message) then click on the survey. Try that....

Thank you very much--that did the trick!

Well, I don't know if they "took" or not (I hit "update" after each motor packs quantity entry), but I filled out the motor survey. One suggestion, Carl: If you could post the original 1968 - 1971 Semroc "Recommended Propulsion Modules" lists for the Semroc kits of that era, it would help us select among your unusual motor types ("3/4A," "3/4B," etc.) for use in your "Retro-Repro" Semroc Swift, Aphelion, Lune R-1, Goliath, etc.

I cannot find that list. As soon as I get the RockSim engine files, I can run a matrix with all our current kits.

Thank you! I see great potential in those "fractional impulse category" motors as being "tailor-to-field" and "tailor-to-model" (especially multi-stage models) motors. In situations where a given field is a bit too small or a model is a bit too light for recovery on the field to be likely with a full "A," "B," or "C" motor, the "3/4" and other fractional motors could fill the gaps without being *too* powerful.

The ones I like are the A3-2T along with the mini B3-3 motors. I love the C5-3 but did not 'choose' it just yet, but if that ever came back, I would definitely be getting those.

Also seen what looked like 'your' version 20mm D5 motor and picked that.

Plenty of others there as well, but only a few of them I would really want as a mainstream motor choice.

I'm with Jason and others.... I focused on choices that are not available from E or Q, and tailoring to sites. I didn't know quite what to do with some of the new-to-me sizes including the "Wide" ones that appear to use ST-8 as the motor tube and the 15mm or 10mm choices. It's sort of a chicken/egg thing for me there.

That you're even considering this is quite exciting news for me. Thanks!

I didn't even *touch* the "Wide," 10 mm, and 15 mm motor choices, but *NOT* for lack of interest in them! I was just so overwhelmed (happily so!) with the other, more familiar choices that I concentrated on them.

The 10 mm and 15 mm categories in particular could re-invigorate FAI contest flying (I know British FAI flyers who would love to be able to buy such motors), and these motors would also be useful for urban and small-field sport flying (a "bridge" between the 6 mm MicroMaxx motors and the 13 mm mini motors). The new Q2-type igniters would make even the 10 mm and 15 mm motors easy to prep, with reliable ignition.

Maybe if all of us who are club members spread the word about this, we could help create a receptive "market-in-waiting" among model rocket clubs, NAR sections, schools, Scouts, and 4-H Clubs (not by *promising* them new Semroc motors, but by encouraging them to compile "preferred motor lists" and submit them to Semroc to give them ideas of where they could most profitably concentrate their motor development efforts).

Nothing posted here is supposed to be mentioned outside the SAM forum! :eek:

No harm done, then. I haven't said anything to anyone else and won't.
