Iv'e been noticing erratic flight behavior in my Mavic and decided to try and recalibrate everything. The issue persists even after firmware update today, and fresh IMU and compass calibration.. I have a 600 foot long nearly flat paved driveway with trees on both sides. The driveway is a straight line to the road. I'm simply trying to fly up to the end of my driveway and back, by flying straight up the center of the driveway at about 6 feet off the ground ... I am flying faster than tripod speed, but nowhere near the max speed in non-sport mode. Doing this seems to go fine for about 50 feet or so, and then the drone will entirely on its own suddenly lose altitude to the point of scraping the driveway unless I compensate and save it. It will also suddenly move laterally right or left entirely uncommanded, and on one occasion flying a straight line it actually suddenly climbed to about 25 feet altitude barely missing the canopy of the trees overhead because I caught it in time but I had to hold full down stick to get it to stop climbing. Occasionally when flying forward in a straight line at about half speed when I go to stop it won't just stop and hover, but will stop and then fly backwards or sideways about five or 6 feet. Obviously the small deviations are no big deal when you're 300 feet in the air over an open scenic area, but when you are trying to fly precisely in a confined area these uncommanded deviations could result in a crash very easily. (I also tried to do a stick calibration on the transmitter, but it wont let me.. every time I try to start the calibration it just pops up a warning to be sure to return sticks to center before hitting start, obviously they are centered, because they are self centering sticks. |
