Does somebody know if the zero point of the Height limit settable in the Naza is the transmitter position or the ground level? For the side limits, I am sure is the position of the transmitter , but I am not sure about the height. It makes a lot of difference if you start from the top of a peak. If it is the transmitter quote, everithing is OK. But if it is the ground level , you set e.g. 300mt and you fly from a top of a peak of a mountain, if your ground below the peak is more than 300mt far away your bird risks to go down down and you can never take it back.
