Looked more like B6-2s at longest.
I do not understand the concept of using 2 clustered B6's in ANYTHING.
A 3 engine cluster I understand. It gives one more than a full C but less than a full D.
It makes far more sense to use a single Estes C6-5, C11-5, C5-3, or Quest C12-4.

Unless one is making a scale Gemini Titan, two engine clusters make zero sense at all to me.
They just add complexity where none is needed. Just use the proper impulse sized single engine.

Let's face it: cluster black powder *anything* is not really needed these days and hasn't been for years. BUT, people still fly them for fun...and what they want to do for fun (within legal bounds, or 'rocketry' legal bounds, lets say) is up to THEM.

As for composites, well, to me, those REALLY don't start until you get up to 38mm, and in some ways, I'd stretch that to say they don't really, really get interesting until you get up to 54mm and beyond (say, J class and higher). I mean, if you are going to go high power lets really pour the coal on.

But, fun and challenge is in the eye of the beholder. Live and let live.
