Are you talking about the festos from 2003 or 2004? I'm more familiar with the 2003 but I'm setting my 2004 pneumatic board up tommorow. From the 2003 I know I had to block the exhaust of the Festo to keep it from leaking through when I would stop the one side. I not sure if they can inherently close the exhaust. If you are talking the 2004 Festos, disregard this post. I get my chance to work with them tommorow after taking a week to basically design a drivetrain/chassis.
