I know this is probably an issue with me more than anything else, but... Every time I fly, the video from the Inspire 1 is amazingly smooth with one exception. If I'm flying straight on with an object and have it framed perfectly, the heli kind of tracks left and right, not flying in a perfect straight line. I watch some of your guys' videos and they fly so straight and smooth...so I have to ask, do I need to learn how to fly? Calibrate? or something else? Any tips are greatly appreciated. Thanks!
