Personally, my priority for new BP motors is high thrust boosters: B14-0, C20-0, D30-0, E40-0, etc. These would solve lots of my staging problems.

Interestingly enough, in another recent thread here, a 3-stage Centuri bird was being discussed. The directions called out only one motor to be used in the 1st stage (of 3-stages flights): the B14-0.

I might be alone on this, but I'd kind of like to see some of the Type III motors again. I know that the 13mm T motors were supposed to represent an updated version of the Type III's. I can't help but think, though, that with the same length and a larger diameter (hence a larger BP slug), you could engineer some of them with higher total impulses than the you have with current mini motors. Booster motors with the Type III design might even stage more reliably than the minis because of the larger diameter.

Add my voice to the multitude calling for a return of 13mm booster motors, too, though. During an Old Motors Evaluation launch last summer, I had a chance to launch a Midget Mini-Brute on an A3-0T - 1/2A3-4T combo, and it turned in a great flight.

Not to be contrary, but there are times when I wish I had a PLUGGED version of the micromaxx II.

B14's = automation

And they don't even have the A8-0 anymore where they could be clustered to the near equivalent of a B16. Of course a cluster won't work in small diameter booster stages.

That ain't contrary - that's brilliant!

Pssst, Mark,

You can fly them now. What you're describing is the current A8-3, A8-5 and B6-0. Just saw them off at 1.75" and you'll have type III's aka shorties. My K-40 Midget clone has flown on a B6-0S to A8-5S combo, and it was great!

[Shush!]

Hey, Doug!

Just between you, me and the lamppost, I kinda knew that already. I also have a K-40 clone all done, and I've got a K-45 Beta clone in the works; both are "for display only," if you catch my drift. But since the man asked, why not put it out there? So keep this under your hat. Ixnay.

Remember: this conversation never happened. Trust no one.

[Quiet, now; someone's coming...]

Mark

Let's come up with a list of the 10 most requested BP motors that we all can agree upon, and hopefully, motor manufacturers will take the lead and produce them. (at affordable prices)
I will start the list with the following
B14's
C5's
mini boosters
Lower power boosters

OK, How about making the C6 engines a full C impulse? Same with the D12. What is so magical about the 2.75" length?

High thrust E and F
A new version of the F7
