and one more question: when it drives forward or back, it is always slightly turning to one side. I tried adjusting wheels, inverting them, removing sensors, etc, but to no avail. I suspect something in the wiring makes one engine get a tad less power than the other, is that again related to the voltage and will be fixed by one of the options I asked before? Or is there a wiring problem, like powering from the wrong pin or the like?
