please first read this... viewtopic.php?f=7&t=28434&start=70 Hi, i tried to do the trick. I calibrated X1, too. It works, but not in a good way because when i move the lever just a little , the camera goes all the travel to 180 and when i move the lever a little to the other side the camera goes all the travel to 0 degrees. I cant move it on steps 180, 90, 60 40 0, etc. I tried moving the lever a little bit, a little more and all the way . Same results. Only one time on a random base i could set the camera at 45 degrees. For me, in that way, it is useless, more if i cant use the app lever simultaneosly, which i cant. What am i doing wrong? I have PV+. all firmwares last versions. I have the tipical lever on the rear of the tx.
