The instructions are not written clearly enough for me to comprehend. Here's what I mean: In the PT2 software I've got "Nazam" selected at the top of the display, "Basic" menu, "R/C" tab. Now: I've currently got my S2 switch set up so that it's "GPS" in top position, "Atti" in middle position and "Manual" in bottom position. All well and good. Finally, the question: If I wanted a switch position to become "F/S", would that be done by replacing one of the current selectable control mode options on the S2 switch with "F/S", using the drop-down 3-choice menu on the right side of the U channel slider? If that's correct, DJI has done a dang poor job of explaining, at least in the English version of the software.
