It may have to do with the way the channel values are mixed to give the desired motion. I believe there is a transmitter option for mixing as well as mixing done in software. Rather than use their "canned" tank or arcade methods, I would write my own code to read the raw values from the transmitter, map the values, and then send the values to the motors. A few print statements in the code to show the values recieved from the transmitter and the values you are sending to the motors may help point you to the source of the problem.
