Ahh....now I understand the E78 comment.
When a question of power comes up, more average thrust is almost always the answer.

So when are those coming out ?
In 29mm, please, not in some 'weirdo' 27mm size.

Well, now that would be an E128, theoretically. Practically, we would probably not do anything in port type greater than 3/4C19.

LOL.
Would not expect any port-burners that size anyway....composites do a better job more safely in large motors.
Would be overjoyed with a 3/4C19-x, B16-x, B14-x, or ANYTHING in 18mm that has a substantial kick over the hum-drum C6 !

Oh, I *LOVED* the old B14s!

I still have some B14s/ B8s, there is nothing like unleashing 5 NS in 3/10ths of a second.
I recently used a B14-0 to send my Astron Farside on its maiden flight. B14-0, B6-0, A8-5
work flawlessly, the B14-0 made the Farside leap off the pad and sent the Farside to a very respectful altitude. the only Black Powder Motor available today that I would compare to this type of performance is the Estes C 11.

There are several problems with the C11-0.
1) It does not have near the kick of the old B14
2) It is heavy due to being in a 24mm casing
3) The pricing stinks; the 'street' pricing is far closer to a D12 than a C6 for nothing but a ton of cardboard.
4) It has too much impulse as a booster over the B14 to be usable in small models with hope of easily recovering the booster stage in a small area.
5) It is not readily available at Hobby Lobby or Michael's stores that every town has...one has to either order them or find an independent hobby shop, most of which want full retail.

FWIW, the latest price increase affected most motors *except* the C11, it is now retail priced the same as the C6, $11.79. D12s now retail for $17.49! My LHSs have adjusted their prices accordingly (which, depending on the shop, is full retail, or ~20% off).

Yeah, for a while there your build threads were like the SEMROC new release channel. I tuned in sometimes just to see what SEMROC was bagging up that week

:)

Here's my votes Carl:

1. Omega
2. USS America

I'm only voting for two. I haven't had a lot of time to juggle much rocketry lately but I'm sure I could come up with one more when you cut something else new loose. Sorry I haven't purchased in a while I really need to get more involved in the hobby again .....

:D

Hi, I just got access to the SAM threads!

Is there going to be a trade-in plan for the Mini Omega toward the Omega? (Just Kidding.....)

I have just one vote right now:

Midget (eagerly awaiting it now....)
