Theres another thread on this that was started two days ago with Air. Did you update to the latest FW? Version .0400 I too had this error yesterday. Can you upload your .txt file from that exact flight. I want to compare flight and power activity for simalarities. To answer your question, the Motor Current Error from my understanding of research, is one of the motors has exceeded a threshold limit of electrical current. DJI may have decreased one of these thresholds shortly in the last update. (.0400) My error occurred shortly after high voltage during a climb.
