Most likely you need to adjust your CG so it's directly on the main shaft. Otherwise, make sure piro optimization direction is set correctly and that your cyclic gains are tuned to their optimum values. Finally, the CX or ZYX prior to firmware 3.5 never had great piro stability, even with the best of tuning. So, if you haven't done so, upgrade to the latest firmware.
