A litte late... but it could be that you are having a sensor problem and the ESC are in sensorless mode. The Xerun series ESC:s do work sensorless but much worse than the Ezrun wich are sensorless only by design.
A sensor problem is usually indicated by a blinking yellow light in neutral i think.
Hope you have solved it already!
