OOP... Out Of Production... I hate the use of acronyms when the OP (Original Poster) doesn't clarify at it's first usage.

I was partial to a 13mm B motor. Can't imagine that in a Mosquito! Might have to try to find a thrust curve and trace it!

I asked about that when I first acquired as stash of 13mm Bs and was told that they are the same as an 18mm B4.

My favorite as well, i've only seen one launch and i happen to have one that took me a couple years to track down.

I miss those motors.

I used a K125 for my L2 using a rocket I built in 45 minutes.

CTI L640 dual thrust. Just picked up one at Airfest, probably my last.

That is a good one.

CTI M2250 C*. Absolutely ferocious motor. I'm happy to have the AT M2050X to act as somewhat of a replacement now, but it's just a bit softer.

Wow. I can think of a lot of uses for that motor. #clusters, #moreclusters

 

[Initiator001]

AeroTech E28.
24mm x 70mm (D12 size).
No fancy propellant and full impulse.
Best part: $4.95 each (In 1988 dollars ).

A case of 18mm AT F55-12T's for me please, now that we have tiny glass airframes and electronics to match!

Only ~24g of propellant too, so should ship hazmat-free....

I'm curious - when did the M2250 become OOP?

AT G55

Miss that one too.

How about the Silver Streaks?

I've got a few of these..

(1) Does Aerotech still make single use motors? | The Rocketry Forum

I did some poking around for a refresher of the K125. I've been in the hobby for a long time and don't recall this motor. But the above link... WOW. 98mm and 20 second burn time? That's awesome!
