    I'm trying to figure out what is the crazy high pitched noise. I heard it on the installation and setup video and now I'm actually hearing it too. What's the scoop? Aside from the that, it's working great.

    Also, which hole on the back of the controller resides the control for the hidden 7th channel?

    the high pitch sound is standard for the Arris.
    helps keep mosquito's away, and ironically one flyer found it handy to help him find his Phantom when it was lost in some high brush.

    not sure which pot is for the 7th lever, but look for some online video's on it.

    I see two holes in the back of the radio but not sure where to insert my flat head screwdriver to adjust the pitch. Anyone??

    I think I saw in another thread that the TOP one controls the pitch.
