OP, care to provide any details? My team's experiments show that you should find the exit speed you need for your range, assume the ball will go 60%-70% of your theoretical tangential free speed, and gear accordingly.

We are doing a one-wheel design that uses the new six inch wheels that came in the kit of parts and a flap on the top to adjust the angle the ball comes out of.
We were just worried that a high gear ratio wouldn't have enough force to launch several balls and it would be hard to get back up to speed.
Geekier than me? That's a goal you can shoot for. You might make it, too -- in twenty years or so. :cool: - Richard Wallace [more]
