I've tried re-calibrating the IMU but it says "cannot get data from  controller". I have tried refreshing both controller & drone using  DJI Assistant which was successful, but that did not cure the problem.
Not really worth it to get it repaired as I was about to list it for sale on  eBay. Just wondered if anyone else has had this problem and knows a less  expensive solution to fix than sending it to DJI.
P.S. I don't have care refresh on the drone
