Good point cowfish, but I've tried poking the wires around quite a bit. I'm wondering now if it is the connection to the electro magnets. Maybe one side has a crappier connection due to cheap wiring and therefore can't deliver as much power to the magent? I don't think its interferance between wires since I get a very distinct left and right with no twitching, but one is just noticably stronger than the other. Any EE people reading that could confirm my above theory on electro magenet strength being the cause due to cheap wiring?
It could be interesting trying to improve the basic design of the bits (or at least the cheaper oems) so that problems of this type would be far less likely to occur. Who knows, maybe it could clean up steering even on bits that currently drive fine? Or maybe its just a $10 car
