    Hi, I have noticed a slight whistling sound when flying.
    I have checked props and motors. All looks fine. Have done about 90 flights with the PV2+.
    Apart from the that it flies like a dream.
    Anything I should investigate or worry about? :?

    Do you ever oil your motor bearings?

    No, not yet? Should I, and what must I use?

    Sewing machine oil works well as it's nice and fine and doesn't seem to be a dust magnet :D

    Is there no way to do this without drilling?

    Can you notice any movement at all outside of the normal rotating movement, like up & down? I get grass debre sometimes and possible dirt from forward tilt when landing.

    Also don't like the drilling part.

    I don't notice any up and down movement.

    Got some oil and a needle and injected a couple of drops in at the top.
    Tested without props. Sounds a lot better. Wind is too strong outside to go and test.

    If you don't want to drill holes, every 10 flights you can pop the top off the phantom and remove the 4 screws that hold each motor in place to get to the bottom bearing. Much more of a pain if you ask me. But other than those 2 methods, there's no magic way to get to the bottom bearing on these motors.
