I'll second this. Our initial prototype would audibly slow down when we shot a single ball because we had too much compression involved. With our final design, we have less compression on the ball and a more compliant shooter wheel. I don't think we've done the PID loop for it yet (waiting for some new sprockets to get in so we can test different ratios), but we can gravity feed in a line of balls (maybe 5 balls/second) with no noticeable change in the wheel speed or power of the shot.
