I'd think that using the small range between completely off and completely on for one of the ports of a switch would be a better speed control. In the parially on state, you'd get constricted flow. I'll have to try it. Kevin

(...) Wow! I saw your first reversible engine and I kind of got lost in all of the tubing. Needless to say, it was quite an accomplishment. Its amazing how far you have been able to take the analogy between pneumatics and electronics. But, I kept (...) (21 years ago, 5-Jun-03, to lugnet.technic, lugnet.robotics, lugnet.build)
