I can't quite speak for the mechanical aspect of the system, as I had no hand in that. I only worked on the control aspect of the system. And since I'm the only member of my team on CD, I don't expect we'll ever get a good answer as to why our system had so much friction.

I was under the impression that one-way valves were illegal. Is that not true?
