    Yesterday I noticed some strange behaviour -the drone was bouncing up and down at about 50cm off the ground, and randomly drifting (both when there is no stick input, in GPS and ATTI mode) After witnessing this, I landed the drone, and noticed that one of the propellors seemed to be spinning slower than the others, and there was a slow oscillating whir that I hadn't heard before. Is this a damaged motor/bearings? Would that be the cause of the drift/bouncing? I have also updated to the latest firmware and have done calibrations - other users have reported that this has caused issues with drifting.

    I've had issues with motors following a recent crash. Ianwood came up with a great suggestion which was to run the P2 for a while, shut down the motors and immediately feel each one to see if one is any hotter than any other. If you find one is noticably warmer it could be an indication of a bearing issue.

    I ended up replacing three motors before my P2 flew properly again! :eek:
