I've been working with Denise. She got the 2.5-inch couplers onto the website and they are orderable. I have an order confirmation in my inbox.
Nice... I just orders a ton of them to match up to the 2.5" tubes that I have.

The problem with the heavy-wall tubes is it's hard to get a non-balsa nose cone to match.
Indeed, I discovered this since my post in back in January. Building a rocket from BT-80H tube and using an Aerotech cone right now as it happens.My Aero Tech noses did ? So do LOC?

Yes that has been known for years
Well, my need was for hollow cones I could stuff electronics into, and back in January, I hadn't noticed that LOC and Aerotech 2.6" tubing was the same as BT-80H. Or maybe I had, but hadn't made the connection to nose cones. In any case I figured it out, and not only that but it turned out I already had a length of LOC tubing and a matching Aerotech nose cone, which I'd bought for some negligible sum from the DARS stash long ago. Ordering another 34" of BT-80H from BMS since I need two fairly long tubes total.Yup, the BT-80H is available from BMS, eRockets, LOC, and AT. At least.
Your inquiry to Estes getting them to make the coupler available nearly convinced me to go in on 2.5", but the tubes are so short. I've gotten spoiled being able to buy 34" and longer tubes of most of the sizes I use. It's academic now because the 2.5" tubes are now sold out. Probably due to a certain rocketeer with a username that starts with "S" and ends with "w."I stocked up on the Estes 2.5-inch stuff this round, not because I think it's just good to have a bunch on hand, but because it's dirt cheap compared to any other source of comparable tubing. It's a nice, big (well, to a LPR/MPR guy) tube capable of L1, maybe even L2 performance, and the nose cone is a lightweight 4:1 ogive. That's a recipe for Little John, possibly my favorite scale subject. With launch 2023 and free shipping, the tubes were $3.24, the nose cones $4.45, and the couplers $1.61. It takes 1.5 tubes per Little John and the nose cones are made of HIPS, so they hold paint without a $30 can of Bulldog. Can't beat it.
But not to all. The difference between the 3.0-inch OD (Estes, BMS, NCR) and 3.0-inch ID (others) leads to confusion and assumptions that Estes 4.0-inch is probably different than the most common other 4.0-inch stuff, too. I've been an application data sponge for awhile and only figured that one out recently. Possibly because I'm not really interested in building stuff that big, but still... It's easy to not know, because Estes doesn't publish the thickness or ID of any of the "PSII" stuff.
The Saturn tube is still BT-101 which is a thin wall tube due to the need for it to be light weight.
The MDRM uses a thick wall tube similar to the LOC tubing.
THey are not interchangeable.
Aww, I missed this. Hopefully they are able to get more up! I still need one.2.5-inch tube is showing as sold out. Hope everyone here who needed some jumped on it.
