basic hydraulic drawing

I'm running 35Bar without any problems, but you don't need to be anywhere near that high for a dozer. 20 or so will do ya...

Tinkering with radio programming while you are using the model, adjusting pump rpm to probably 80% max to conserve battery amps shouldn't affect hyd speed too much, if at all. And using channel mixing to mix pump rpm with valve opening to conserve even more amps for longer run times per charge. Valve is neutral, the pump is at a minimum of 20%. But as you move the stick to open valve, the pump rpm increases at the same ratio.
