Hey, what happened to those A8-0's and A10-0T's we were promised?

I can only make them one at a time and I don't have a DOT number.

Don't forget photo rockets - the Astrocam 110 recommended the C6-7 simply because the rocket would be pointing down when the ejection went off (and thus, would get a photo of the ground rather than the sky or horizon).

I received the following e-mail response from Estes yesterday after I'd send them a similar question:

"…the engines you noted below are planned for this year, I just can’t give you and exact date when each will be released…but hopefully all will be available by fall. Check the website starting in August or so for more info."

I had asked Estes (via their website's 'Contact Us' form) if they were still planning to re-release any/all of a number of motors I'd heard (on here) they'd been planning to re-lease: A10-0T, A8-0, C11-0, C11-5, and C11-7.

The C6-7 would be a disaster in the Interceptor and the Saturn 1B. At the very LEAST the recovery system would shred as well as if using a kevlar shock-cord leader you would get a zippered body tube also.
Most often you can get away with using a C6-7 when the C6-5 is suggested if the body tube is BT-50 or smaller in diameter, with BT-55 it can be a tossup- something like a Cherokee-D with fairly low drag and light weight would be okay on a C6-7, whereas a heavy and draggy Interceptor most certainly would NOT.
ANYTHING BT-60 or larger will NOT be okay on a C6-7 as a single stage engine EVER; for BT60 and above it better be the upper-stage of a two-stage rocket.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !

They may not be cool for flying your particular rockets, but I'd buy ANY 3-pack of Estes motors for $2 each, whether I had a use for them right now or not.

PLEASE don't fly the 1B or the Interceptor on the c6-7! BTW, we need to see photos of your 1B build BEFORE you destroy it by flying it on (4) c6-7's.

You could however fly the Saturn 1B on a cluster of 2xC6-5 and 2xC6-7 though as the ejection charge from the C6-5's will be PLENTY to eject the chute and the -7's just venting to the top of the open tube. This actually would be much easier on the airframe and would be a good way to use C6-7's !

That's a good idea! I was probably just about to think of that.

Come now GH, you of all people.......
Back in the '80's I'd fly my DRM all the time on a C6-7 with a 24" chute, had a great pucker factor but never failed to recover safely. That said, not too sure I'd do it now.....
