I don't want to derail your thread with a discussion about the ring-fin Warlock --- I'll start a new thread on it if I decide to pursue it. But here is the basic idea.
This is what an Estes Curvilinear looks like:
It's s small rocket for mini A10-3 engines. The proportions are very similar to the Warlock's, so I thought you could probably add a similar ring fin (if that is the right term) to a a Warlock for a cool Sci-Fi look. Here's the basic idea.
I't's not exactly to scale with the Curvilinear, because the ring on the Warlock has to be big enough for a rail to fit through. This is 11" in diameter to give about 1.5" clearance, and scale would be closer to 9", I think. Curvilinear is also a 4-fin rocket, while the Warlock is 3.
Anyway, it's just an idea I've been mulling over. I want to keep it flyable on L1 motors, so this might add enough weight and drag that it would move more into the L2 range, in which case i would not do it. I had a similar issue with the pod rocket modifications I made to a Mega Der Red Max --- it is kind of heavy and draggy for G motors now, and the weight is what forced me to try for L1.
Like is said, I don't want to distract from your thread, but thought you might want to see what I was talking about.
