Re: What wheel to use for the flywheel

Try rolling the balls through the shooter by hand, putting them in the bottom and spinning the wheel with the robot powered off. This is a pretty subjective and variable thing, but you want the ball to resist going through somewhat without really getting stuck or sliding by freely. (There also should not be one spot early in the ball's path that is much tighter than elsewhere.) This is a rough indication of whether you have a dearth or excess of compression. If you have too little compression, some balls will probably not catch well and receive less energy than others. Conversely, if you have too much compression, the aggressive deformation the balls are undergoing can make their trajectories hard to predict upon exit.

The equalizing factor, as Clint said, may well be trying a softer wheel that allows more compression to come from the forgiving wheel rather than the balls.
