[DFTF] Brave Pneumatic World...

Speaking of pneumatics, one area that you need to watch is the flow resistance of solenoid valves, specifically the Cv. Many of the new solenoid valves are more efficient than the FIRST specification and are thus not legal for FRC use, at least by the 2011 rules.

on that note, I will add that multiple soleniods per pneumatic actuator is no longer lega as of the 2011 rules. prior, one could use multiple solenoids to ither increase flow (dymaically when they are independently controlled) or to allow variable positions (separate intake and exhaust solenoids).
