I just got an Radiolink RC4GS with 2 Radiolink R6FG receivers, with gyro's, With the gyro's enabled both cars spin in a right circle after going forward maybe a foot they are both mounted horizontally. If i pick the cars up and move them side the side the wheels change direction like I'd expect but going forward i get nothing but circles. Is there a setting in the radio or something else I'm missing that is causing this issue? only had this radio for a few hours.

Not sure I understand what your problem is, but I think you might want to experiment with changing the direction of the gyro by making a series of button presses, I forget the exact sequence, but this video here should help you figure it out:
