I think so. I just need to find a 3d person to operate the camera.

My stroke is 3.63 inches, so that would equate to an average piston speed of about 1200 fpm. I probably could go down a bit and not sacrifice engine efficiency (well, not that much, anyway).

But you're right - this thread is about the aerocap, not gearing. Heh.
