We have not driven it with a trailer as of yet, but on the playing surface it may not be a huge problem, besides the fact that the weight of the trailer may pull the back end of the robot a little bit.

Oh, and the robot drifts. A lot.
We had the same result in similar testing. Our base was being driven from a battery, so no speed control. We think some of our initial slowness during turning was because we were "Flooring it" and breaking traction.

Can't wait to get more wheels in so we can test with 6 wheels, and most importantly, with at trailer.
