The little lever in the back of the controller that used to control the camera tilt used to work great. Today, I went out and it would not work properly - camera only pointed down or forward and didnt give me the ability to smoothly point it where I wanted. Gimbal was working. Downloaded the software, updated firmwares on everything. Software readout confirmed what I was seeing. The lever controller is messed up and does not sense the input points in between. Tried calibration, but there is really nothing to calibrate if the radio's potentiometer is only reading two points in the range. Took out the screwdriver and opened the controller. The lever is connected to a phillips-head potentiometer (pretty cheap junk!). The rotation is smooth and appears normal, but even when manually moving the potentiometer I saw the same in the software readout - position jumps from about -80% on the scale to +90% with no sensitivity in between. I assume that the potentiometer crapped out. I've only had this thing for about 3 months - is it worth contacting DJI for warranty? And if so, what should I expect? I also see that there is another potentiometer right below the one that controls the tilt. The controller body has a hole in it presumably so that you can adjust this potentiometer with a screwdriver. I tried google and could not figure out what this was for. Any ideas?
