@TheLordsChipsBuilder Yes you may do that, but note this for future reference:
Rule <R11> states:
The bolded text “legal VRC pneumatic system” is interpreted to mean any sort of pneumatics set-up, regardless of how many cylinders you have on your robot. However, <R18> states that you may have no more than 2 air reservoirs on your robot, but that’s the only restriction on the pneumatic system. Thus you may use an unlimited amount of cylinders on your robot.
