but if you use an arm to extend the distance (And velocity) of the ball it will shoot a lot more. i had a phyz project that had size limits of 25cm high x 50cm long and i was able to shoot a tennis ball 10meters using a simple lever arm with 2 3/4 bore i think 6in stroke cylinders at initial 100psi with 4 FIRST tanks. with small sling arm.... sling arm would be cool but quite hard to reload in our robot's case tho
