    Hi
    how do i adjust the servo centering? obviously i set the correct pulse width but my servo horn isn't 90 degrees to the servo. i've got it as mechanicly close as possible

    There is no tail servo centering option with the beast x.
    You should be able to get the horn at 90' try a different horn if you cant with the one your using now, then just set the rod length so the slider is in the middle, set your endpoints, done.
    You may have to adjust your rod slightly at the field to get even stops on the tail though but remember to reset your end points again if you do. Then you can tweak the 'tail dynamics' pot (3rd one) if you need to to get a nice crisp stop.

        Thought sub-trim was a no-no with BX

              Yep ... all you can do is adjust the rod length, set the servo travel limits and BX takes care of the rest... mine was a slight bit off 90 when i setup but the tail holds fine
