Hey Hey all, Wanting to garner something from the collective experience of the community. I took rotors off and whilst turning by hand there is a distinct resistance and rough feel that comes and goes in one of the rotors. Im thinking of blowing it out with some air in case a grain of sand or something possibly made its way in there. Any thoughts Had the mavic a little over a week, last night i noticed the mavic appeared to have a little trouble keeping position stable during a short flight getting a couple of elevated shots of sunset. I flew it back to me when i first noticed but it sounded fine and seemed to correct but it did start to drift around a little at times. I got a chance to take it out for 15 min today and during flight seemed fine but when i brought it in to hover i noticed its rotors dropped in and out of harmony and it was drifting a little.
