We are using a 12inch pneumatic wheel. We use 12inches because the frisbee contacts the wheel for a longer period of time. Also, compression is a big part of it. The wheel on ours is fairly flat. It doesn't have much air in it. Therefore, the tire cups the frisbee. We have found the happy medium when compressing the frisbee. If you have to much compression the frisbee will just spit out and not go to far because there is to much friction. If you don't have enough compression, the frisbee won't get that far.

Consistency is hard for sure. We made sure our platform on the curve was slick so the frisbees could slide easily. Also, our curved angle had to be touching the frisbee the same amount of time all the way around the wheel.

The hopper we are still working on. When the bottom frisbee is sitting there waiting to be shot, it is getting sucked in by the wind of the wheel. And when it does that, our frisbee's cup. Also, the whole platform is vibrating, so the frisbee's move a lot. To fix that, we are going to use a pneumatic piston that is vertical and extends on one side of the frisbee, when doing that, it keeps the frisbee in place. When we are ready to shoot, we will pull that piston down and then fire. It then repeats the process.

I hope that helps.
We are using an 8" pneumatic wheel. We have been able to shoot our frisbee far, but not consistently or accurately. Thanks a ton for the info.

Is there anyway for you to describe the amount of compression you're using better? I know it's hard to tell. We think we have found the right amount, but we could be wrong.

What material is your platform made of?
