I am using a "manually operated control servo valve with feedback" to regulate oil flow which is directly proportional to the speed of the ground drive wheel and associated ratios created by different sprocket combinations. It is quite accurate and reliable. No electronic boards, sensors, pmw valves etc. It does use a fixed flow of @ 2gpm from one tractor remote-deere 8000series.
