[Ultimatum]

You might be having the same problem we were. In driving around a lot, the bottom frisbee can occasionally move forward, causing the second frisbee to fall back, and thus making your piston hit the second frisbee instead of the one on top. I would recommend some sort of grip tape on the bottom of your hopper, so that the frisbee on the bottom of the stack has a hard time moving forward except with your piston hitting it. We were not able to fire in teleop in a large number of our matches, and after one piece of grip tape we shot fine, and put up 60 points of frisbees in teleop.

Unfortunately I don't have any pictures right now of our setup. But if your problem is the bottom frisbee sliding forward, grip tape works wonders.
