Pull_Up said:If you haven't changed into NAZA mode then the S1 switch won't make a difference - if you've got satellites then you'll be in GPS mode wherever you put the switch. If you have switched over to NAZA mode via the Assistant software then you'll have access to S1 functions to flip between GPS mode and ATTI mode.
Quick video describing the difference here:

I really must dust off the X4 and throw it around again - it's been sorely neglected recently, poor thing. Relegated to being used as a prop in low-fi videos!
Thanks again Pull_Up your videos are very helpful. I have to admit I didn't read the whole manual (and didn't see that bit about switching to NAZA) til yesterday, since I came from a phantom 1 and went straight to flying my P2V. A bit too eager I'll admit, but I love the longer flight times and FPV obviously.
