Yea, I have had terrible luck. The first two I sent back because the gimbal horizon was off on both. I calibrated perfectly fine on a 100% level surface. Cold. IMU everything. The 3rd one was the same so I just thought sod it and put up with it.
Almost on every flight the aircraft would disconnect, let alone weak transmission signal which I would even get in an open field sometimes. A couple of days ago, during flight the gimbal spun out of control randomly for no reason and then went back to normal. Frightened me but everything seemed okay after that. Then today happened.
I know all this was pilot error but still, there was just something up with my drones
