1/12 Scale Excavator

[JAMMER]

The noise sounds like it coming from the motor not the pump. What is confusing to me is you shut it off and start it up and it will run for a while before it starts to squeal again. I guess I will have to pull it apart and run one at a time and see what happens. I will have a video in a few days my Mac man told me I had the wrong cable but he is going to put it on you tube for my nothings spectacular but I was digging were waste management truck turn around to pick up a container and it it packed run a crush and tar so it was hard digging and of course if I had self centering sticks it would have been easier to operate but I tried.
