We calculated that the ball was coming out at a little less than half of the allowed speed. Did not go too far.

The wheels are at a 45 degree angle and by the time it had traveled about 6 or 7 feet it was already back to the height of the wheels. I'm not sure how to explain this better.

by shooting the ball at 500 rpm, you will never achive the length you need. unless you are shooting while parked on an angle on the ramp. if you were to be scoring from a distance of 20+ feet, it would have to at least spin around 6000-9000 rpm depending on the size of your wheel and the motors you use. try a direct drive from the chips and c what you get from them. id step up to a higher rpm motor. by using chain and sprocket you lower the rpms dramatically.
