Bill had live motors that he wanted to demo (i held them, or did until Steve Lubliner dropped them as I gave them to him!), but couldn't due to paperwork issues. They looked very clean. Thin casings, brown nozzles with small ports and not much expansion. I figure due to the limit of propellant that the total impulse will be around 50ns.

The D18's were not so vaporware, as they really already existed as Aerotech's D21.
The only difference was that I think Bill was going to take the D21 design and apply chinese manufacturing cost savings. I assume he wasn't able to get the savings he wanted, and mixed with the lukewarm reception from the hobby industry at iHobby 06, that sorta doomed that project.

Aerotech would have made the 18mm Ds, not the Chinese. But like Craig I say what is the point? I would not pay that much for a single flight. The 18mm Ds also only really got to the casing testing point... There are cases of these new BP motors in actual exsistence in his warehouse. They are awaiting certification.

Ok, that's why I never understood the whole situation. To me it only made sense if Quest could sell them for something way cheaper than Aerotech's retail. And the only way I could see that happening is manufacturing in China (or equally cheap location). When I asked Gary about it in Cinncinatti 3 yrs ago it indeed sounded like AT was going to do the manufacturing... and it made my head 'splode. So I prefered to believe the China route!!

Here's some pictures I took of the new Quest motors at the Vendor's forum at NARAM-50.

I'll be even more impressed when I see them in action and have some specs to look at and NAr S&T announces they have been certified.

The only problem I have with the new Quest motors (D5, E12, F12) is that they don't fit into ANY of my rockets that I would use them in.

We don't really need a reason to build new rockets, right? But now you do anyway
