If you power them with the same pwm value it's really not an issue based on the testing we've done. Been working fine all week for us.

I even took a pair driven together in my hands and tried to get them to rotate as differently as possible, they definitely handle a good deal of force difference while running together (at least at full speed).

Perhaps on a kicker they do not run enough to be problem. They are window motors so for safety they are designed to cut out when they stall on something and heat up. Not really the ideal motor to build robots with.

We were having a similar problem last weekend. If you want, shoot me a PM with some pictures of your set up and I can try to offer some advice. We were able to make ours work with two windows powering four wheels (one on front set, one on back set). It sounds to me like you've got some friction somewhere in your system, just as we did.
