Re: Slowing down the action of a cylinder with flow control, mechanical or via softwa
There seem to be some errors in the information being given here. Let me try to clarify.

Flow control fittings are permitted (if they are "connecting fittings"). Flow control valves (and check valves, incidentally) are not permitted (because they're not any of the things permitted by <R66> and the rest of the pneumatics rules).

The fittings Chris was referring to are like an NPT-to-tubing elbow connector, with a needle-type adjustable flow control screw built in. Those are almost certainly legal, because they are usually understood to be a type of fitting. A flow control valve, that isn't also a fitting, is almost certainly illegal.

At an off-season event, do whatever the organizers require. If they're alright with teams taking reasonable liberties, go right ahead. (Usually there's no inspection.)
