    Prop Vibration

    Got a 27 pro max on 21 XRS
    When I idle you can feel the prop vibrate.
    When you get up on plane runs smooth as silk
    Anybody got any ideas. 3 holes have a plug in them with
    one without.

    Uneven venting can cause "Exhaust Rumble"....... This is what you have.

    Is it a solid hub with the strips? Do you possibly have prop rattle. Mine disappeared after changing the strips on my solid SSR hub. I have a ProMax but all the plugs are in it.

    Power poles? Some power poles will drag a little causing you to feel a little vibration
