Yesterday I experienced 2 episodes of loss of throttle control while descending. The day was windy and the DJI was moving laterally so it was not prop wash. Nothing I could do to throttle up. Once I shut down the motors I could take off again but quit flying after the second episode. I also have never been able to get the gimbal to respond to the Iphone vision app. I have installed the latest firmware and made the suggested pitch limit mods. Any ideas?
