rc4wd excavator
I have a small problem that I need a little help with.
I decided to let my kids and their mate play with my excavator. That was the start of a few problems, someone decided to play with the radio settings.... So far I've managed to get it running but it has no power in the hydraulics, it's almost like the mix switch is turned on. Have checked the operation of the switch and I can see it turning on , on the radio. The pump speed is good but no power, I can see the 4th valve move with stick movement of the cylinders. Have checked all the obvious to me things, like oil level, pump direction ect I am at a loss, any help would be appreciated. Cheers andy |
