While the thread is a fun way to dream, 99% of it will never happen. Estes is set to run at max efficiency, for their engines and entire rocket line. Doing what you ask can't be justified in $$$.
Of the choices in the poll, I'd like to see the B-14 series come back and if possible, a D-18 or D-20 series. Other than that, the current line of A, B, C, & D engines are all VERY reliable and I'm sure, very profitable. Why would they trash them to develop the range in the poll just to cater to the smallest faction of their customers? It makes no sense for Estes. If you need the better kick of a D-20 or C5 just cluster a pair D12's or a pair of C6's. From what I have SEEN, Estes made the right choice when they dropped the C5 CATO machine. The lower end E's aren't much better below 50*F. I wouldn't use either one, ever.

Estes had ONE bad batch of C5-3/C5-0 motors out of their entire production run.
ONE batch of C5-3's ONLY. Makes zero sense to continue the C6-3/0 when the C5 is a much better motor for EVERYTHING. The E9 is another story and I have about zero use for those.

Anyone know which batch of C5-3's was the bad one?
I have a bunch and just acquired more, so I'd like to check all of them. Allen |

Do a forum search here. I think they had an "X" in the date code.

Looks like any C5's with an "X" in the date code were bad, according to Shreadvector. The most recent ones I have are coded C1D6.
No idea what date that would be, though... Allen |

As long as there is no "X" in the date code and stored properly, they should be fine.

Guess I've been lucky - I've flown quite a few C5-3 (Estes) and C5-0 (Centuri) with no problems. No 'X' date codes, though.

Paul, Yes, I’m constructing the booster similar to the Comanche-3 booster. I have not glued in the coupler yet. I haven’t decided how much of the motor should hang out. The Comanche-3 instructions have the coupler inserted 1/2” into the top of the body tube, but the Farside-X have the coupler just 3/8” into the tube. I’d welcome any suggestions, especially those that that have made the change to 24mm booster power. I’m leaning toward having the coupler inserted 3/8”, with the motor hanging out 3/8”. Here is a picture of my booster with the body tube tabs for fin reinforcement, after gluing, but no fillets. I have given them 4-5 thin applications of Titebond Trim and Molding Glue, wiped after each application, to build up the fillets so the tabs are buried. It’s been really cold here so I’ve not tried to take it outside to prime, and see how it looks. It feels very smooth.
