Doug86, you are absolutely right. My bad and my apologies for the wrong information.
I did 3 flights today where I reset to home point to a higher altitude.
After take of I climbed straight to 35 meter altitude and then I flipped the S2 switch more than 5 times (reset home point).
Then I went out to 150 meters and started to descend to 15 meters altitude.
I triggered fail safe and after 3 seconds I got the message on my screen return to home.
The Phantom turned 180 degree first and then climbed to 55 meters, which I did not expect at all. I thought It would climb to 35 meters. The climbing went very slowly, it took some time. When reached 55 meters It flew back to the home point.
I did 3 tests. The first one failed. After I triggered fail safe it climbed to just 20 meters altitude.
The 2 other test as described above. So I learned something new, thanks.
Geert./.
