    have the P-4 and need to change out motors. Orders them but a little in the nerves side. Starting getting high pitch sound knowing bearing is going just my experience flying helicopters.
    If anyone close to Oakwood Hills,

    Easiest way to eval. is to test post-flight temps of all 4 motors. If all similar you're good to go.

    You can usually feel when a bearing is going.. Turn the motors by hand. They should all have the same resistance with no gritty feel.

    With the props attached, flip the motors with a finger. If you flip them all with the same force, they should all spin the same amount. For instance I can fip a motor so it turns about 3 times. If one wont spin that much, then I'd suspect the bearing.

    If a bearing is gone, why not just send the drone in under warranty? That way you can be sure of the job being done right.

    I would avoid sending my drone in for warranty if I could. DJI reserves the right to send a refurbished unit rather than repair one that is sent in, and there is no telling what condition the drone was in or how many flights it had before it was refurbished. No, thank you.
