A Simple Improvement to Driving

That's because they're drill motors. The drill motor gear box turns one way faster than the other. One way you can fix that is by not having one drive train mirror the other, but actually build it, so that it looks exactly like the other side. Example- Our drivetrain is in an L shape, what we have to do is make it into an upside down 'L' Shape, so that the motor is in a different position, not right next to the other one. It should sorta look lik a demented 'H' right next to each other. That should fix your problem, that is if you're using drill motors. If you're using another kind of motor, then I don't know.

one thing. maybe you just phrased it confusingly, but the gearboxes do not turn anything faster in one direction than the other, it is as Matt Attallah says. the brushes are timed advanced in one direction. which means the brushes are not centered from the permanent magnets

Oh, my bad, sorry, I thought it was in the gearboxes.
