Re: Pistons not extending fast enough?

You may also wish to look at the flow rate on your solenoids. We are using a new solenoid we bought that has a much higher flow rate than the solenoids that were FRC legal last year and before. No flow rate restriction this year - only limit is port size.
Could you perhaps provide a link or a google search directing me to solenoids similar to those you're using? Currently we've got some solenoids left over from the early 2000s, and I'm not sure what teams are using now.

As for the cylinders; if the diameter becomes too small, wouldn't they not have enough force to push the ball + platform? I will do some calculations and figure out how much force would be needed from each piston to move the ball however, and will certainly see what the smallest piston we can use is.
