Re: FRC/VEX Challenge

I was looking more for balls I could find in actual stores without having to order online. We will order online if necessary but we kind of need them right now, so I was more interested in somewhere we could just drive down to and get a few. I've been told Walgreens or a similar place might be good for stress balls, any other ideas?

Making a flywheel out of Vex parts is very possible, we've done it using two of the 2-1/4" wheels (with the tread on). The previous gearing ended up being a 1:24 ratio with a single motor, and we got the ball to shoot 3-4 feet in front of the robot (that is the distance until it hit the ground, from a shooter about 18" tall mounted about 12" behind the front facing forward). The current gearing is a 1:40 with two motors, but we need to reprogram before we can test it, so I will have the results of that tommorow.
