2. Design based upon 1/2 max motor speed to accomodate any battery issues, allow for an extra pulse to get back up to speed after a shot, and so we can have some room in case point one above was not concervative enough.
Upon testing, we shot a ball 35' at 30 degrees (with no spin on the ball). Based on this, we're pretty confident that we're at 12m/s, as this was FIRST's indirect measure.
Since then, we've lessened the top drum speed to generate a back spin, giving us much better control at the same type of distance.
In order to get a final number, we'll be looking at a buying a speed gun (which I'll use with the baseball team I coach in the off-FIRST-season).

sorry but finally i found you again, i was trying to figure out which team it was who made that shooter but hey now I know, anyhow my team desperately wants to know how you built that,we hardly have anything, we have replicas but they're hardly working, could you give us schematics of what you did so we could make a similar model. It would help us so much.
