I can't tell from the picture, what motors are you using?
We're using a 550 through a 4:1 planetary on each wheel. The design was actually inspired by your prototype. Thank you for posting it!

Single motor to control both wheels? If so then that's a clever way to save weight.

Negative. One motor on each wheel. We felt that coupling the wheels would be a "double jeopardy" of sorts (when the first wheel slows down, it'll drag the second wheel with it). Also, doubling the power allows the shooter to recover more quickly between shots.

Ah. Next question would have been something along the lines of asking the tradeoffs and the worth behind it. How do the Banebot wheels do on getting back up to speed? We just ordered a set for our shooter.

We haven't had a chance to extensively test it, but we also haven't been able to put frisbees through the the shooter fast enough to slow it down. Take that as you will.

Re: pic: 319's Small Wheeled Shooter

Have you tried any slighter angles to the ground for more distance? Is it giving them enough push to make it somewhat across the field?
(or maybe that isn't your goal)

We still have some adjusting to do. That's why we tried to get it functional as fast as possible.

We're happy it helped. What are the wheel diameter's right now?

Right now we're running a 2-7/8" on the first wheel and a 3-7/8" on the second wheel.
