Evening all, I've just got back from flying my P3 4K, and am still having problems with range despite trying a different location to the previous evening. Today's flight was in a large parkland with a lake approximately half mile wide, 1/3 mile long - No houses within miles or anything tall. I have installed the FCC software mod from a thread on here, and it says transmit power for the FPV is apparently 20. I checked again just before flight to ensure it was still set. It don't appear to have made any difference. The quad can only fly away from my position around 30 meters or so before the FPV and location data disappears off the screen (signal lost). As I can still physically see it, I fly "blind" going further away very slowly. At around 50 meters approximately the control looses connection and RTH kicks in to bring it straight back. This is of course a long way short of the claimed 1200 meters. While I don't expect to achieve that, I was hoping for at least halfway, instead of actually only being able to achieve somewhere in the region of 5% of the claimed maximum. Anything else I can try?
