Ive partially rebuilt a crashed Phantom3 advanced I recently bought. Ive replaced 2 motors that spun a little rougher and Ive temporarily straightened the gimbal yaw arm which was bent badly (new one is on its way). It works now, but Im having quite a bit of jello. Just looking at the phantom flying, it doesnt surprise me. The phantom seems nervous in the air, as if with too high PIDs. There is a slight vibration in the frame that seems too low frequency for prop inbalance, on the order of 10hz. Really, as if too high P factor. The gimbal and the landing gear shake a lot more. Its difficult to capture on video, but Ive tried by recording this with my mobius at 60FPS (be sure to watch in 60FPS): And no, it doesnt hover that badly, Im flying it to capture different angles and movement. In reality its worse than it looks here. I can best see it on video around 21 seconds and 1m32, but its still difficult. And I realize Im flying low, but 3-4 meter up, its the same, I just cant capture it on video there. There was some wind when I did this, but it also happens with no wind at all. This is with brand new props. I did not balance them yet, because I cant with my prop balancer. Again, I have a phantom prop balancing rod on order. But it would surprise me brand new original props would be so badly out of balance to cause this. Also with the first pair of props, which admittedly are slightly worn, its about the same. I did all the obvious things, like recalibrating IMU, gimbal etc.. Any other idea's ? If you hover your Phantom 3 in front of you, do you see the gimbal and landing legs shake at all, or anything like mine?
