I2 drifts to its right by a couple of meters after braking is applied

Hello, wondering if anyone else is seeing this problem, the I2 drifts off to its right a few meters after letting off on the throttle just as it's forward motion is stopping and breaking is applied. I have done a FW refresh on the aircraft, a RC stick calibration, an IMU cal, and a compass cal. The problem is still there, so non of the above appears to have fixed my problem.

Thanks
