new to this forum and to drones in general. have owned a phantom 3 professional for just 6 weeks. small set back in the first week; noticed that my videos had an occasional shudder/jump/twitch traced it to slight sudden movement of camera when aircraft was stationary. sent video examples to DJI, got a return authorization. within 2 weeks the drone was returned. new motherboard. no charge. now happily experimenting with the new point of view provided by a floating camera platform. enjoy many of the discussions on this website.
