Hello (please excuse my poor English),
I am flying a P4pro since a few days. It is already the second "replacement" drone, thee other two had to be returned because of several problems. Before the P4pro I had seveal kit drones, then an Yuneec Typhoon H and an Phantom 4 (non-Pro).
The first P4pro I received had a problem with "hovering", it hovered VERY unstable, massive "wobbling" back-and forth and left-to-right, about four times a second. The sound was very strange, like "Wow-wow-wow..."
It also had a very soft camera lens.
I returned it and got another P4pro. This drone hovered stable and had a sharp lens but it could not hold the yaw position of the camera gimbal; after every turn the gimbal yaw was "creeping" very slow for about 30 seconds from right to left, turning about 10-15% of the horizonal viewing angle.
I returned this P4pro too and got the third.
First flights were perfect, no "wobbling", no "gimbal creeping", and the centering of the camera lens was clearly the best of the three.
But a fed days later, when the drone hovered high over me, I again heard the "Wow-wow-wow" propeller noise, and after reducing the height, a VERY strong "wobble" when hovering was visible.
The drone also reacted "sluggish" and "pardox" to some steering commands when "wobbling". Trying to fly forward resulted in a quick left-then-right yaw turn of the drone at the start, leading to a light "zig-zag" flying.
I immediately landed and re-calibrated compass and IMU.
After that, the drone flew without "wobbling" and reacted precise to the steering commands.
But only for a few minutes, then the "wobble of death" was back!
I tried to land, but the drone was almost out of control, at ~7 meters it crashed into a tree, ripped off the camera at the gimbal yaw arm and came down.
thanks to the low altitude and soft ground, no further damage of the "drone core" itself, not even a greater scratch or so. "Only" the gimbal yaw arm and the black ribbon cable of the gimbal are broken.
Did somebody here experience similar problems, like "wobbling"?
