Ok so I've update my H to the latest Firmware and loaded the GUI on my PC and when I go in to change the height limit it shows that it is changed. I then disconnect the H thru the software and once that's done I unplug the unit from the pc. I then power cycle the H and turn on the ST16 controller and the height limit still shows 400'. I've done this multiple times and it still doesn't change the setting and I'm not sure why.........anyone else had this problem?
