Posted this on another thread but thought I would also share it here. Here is a video I created to compare how far I could fly in CE mode (APP version 3.1.28) and then after changing to FCC mode and using app version 3.1.8.
CE mode triggered RTH after only 1,700ft (520m) at 300ft altitude.
FCC mode got to 10,000ft (3,050m) at 300ft altitude on same flight path.
To switch to FCC mode, I followed the instructions posted here (
Switch to FCC mode in Europe, and fly miles instead of just 300 meters with P3SE) I used option 2.
