RC4WD Dozer, modifications, upgrades, settings.

I swapped one of the self centering wheels with pot to control the pump and same side stick for the blade.

Problems so far what I have noticed is that tracks start slipping very easily on any moist sand / mold.

Every time if I have not been using the dozer for weeks I get very bad arcing from one of the motors or both and I need the take them out. Could hydraulic oil cause it because I haven't done nothing to the over fill tube and the there is always some oil under the cab etc.. here is video of this very usual thing for me https://drive.google.com/open?id=1hf...0mcSmi_8UUGGaQ

Third problem is that cylinders don't keep pressure or position or how it is said? Ripper is lifted up but it comes down very slow and also blade. I need to raise ripper time to time when running.

And the last one is some times the pump struggles to start spinning even when put in full speed, using hydraulics finally gets it running normally. Like the oil flow is restricted and jamming the pump?
