so i was hoping someone can help we witht his. I have a almost brand new phantom 4 pro flew it a handful of times, less than 2 hours flight time. And this morning i wa trying to calibrate the gimbal by using autocalibration and everytime i try it gets stuck at 50% and the only way for me to get it back working is turn it off an back on again and still wont calibrate. i have the latest firmware and the drone is brand new and nothing else is wrong with it, someone please help.

Aloha rick,

     That should not be a problem.  The calibration hangs at about 50 percent for a minute or two (or at least it does with me).  Best to just walk away and make yourself a cup of coffee.  When you come back it should be done.

Aloha and Drone On!
