    Bearing Lubrication???

    Does anyone have ANY info on when or how to lubricate Phantom4 bearings. DJI seems to be totally silent on the issue and motor bearings on a P4 are inaccessible. Could it be they are sealed and "good for life" or what? With over 40hrs on the motors now I'm getting nervous and beginning to worry...
