Re: Rc4wd excavator valve question
The pump motor is just to fast on 12V so I run mine on 7.2V and as I have showed Izzy and a few others it digs just as well on 7.2V I do give up power to the tracks at the moment but I have a 4:1 gear reducted motor to put in it then I will go back up to 12V. The forth valve is a dump valve not PRV and since when it is open ther is no real load on the pump or motor. I have my pump set up on a 3 pos switch 0,50,100% it is mixed so you can run it from a dead stop but i usaly run the pump at 50% for no demand and upon demand it goes to 100%. As soon as you move any function the pump kicks up and the froth valve closes.
This is just how I have mine set up and it works good for me and I am happy with it. I think I will be even happier when I get the new pump motor installed.
