[pugs]

Yes, you'll be producing pressure almost instantly when the pump starts to move, but you won't have full flow till its up at full speed. In the interest of saving battery juice, both the switch controlled and ESC controlled pump are good options. Could think of the ESC/wixed as a load sensing system that only pumps whats, needed, when needed which will also help with heat generation (so will the switch controlled). Being that the valves are variable flow, the switch controlled should give the best performance. Meaning the valve spool position is more of a linear relation ship to the speed of the cylinder being moved, where as with a varible speed pump and a variable valve, the relationship is more arc'd.

The best IMHO, and not sure if possible, would be to have the pump shutoff when not being used like the switch does, then when called for it ramps up speed, such that say 1/4 of stick movement and its at full speed. Would still give you some really slow movement for detail stuff but a more predictable movement at anything over 1/4 stick.
