    I bought a sg-9120 motor a couple months ago or longer and remember shortly after buying it a thread here that discussed the fact some of the chart information for the declination setting or one of the other settings was either wrong or the indications on the motor themselves were wrong. I am now ready to install the motor but cannot find that thread particular thread. Must be putting the wrong "key" words in during my search.
    Anyway if anyone knows the thread or knows what adjustments I need to make during the install that deviates from the instructions, I would appreciate the help. I seem to remember Brian at SatAV made a comment in the thread.
    Thanks in advance.

    30 & 40 come to mind. Think it had to do with the bend of the tube. 30° or 40°. The formula as printed, states 30, but may need to be 40, depending on the bend of the tube.
    All this by m e m o r y, as good as that is(???) Hopefully someone can confirm, or ???
    (Don't use a motor myself, I mounted a Ku to the BUD, but I read a lot of posts)
    The worst case try 30 in the formula, and if that don't work out, recalculate with 40 and try again.

    The manual incorrectly states to subtract the declination from 40, but instead it should be to subtract the declination angle from 30 degrees.
