I was flying just about 100m as the control told me satellite connection lost. Ok, no problem, he can come back. But he was going down in the middle of a forest in the mountains. No chance to climb up there. Really a pain. I have tested this come back function and it worked perfect, why this time not, no idea. I tired to climb up there but had to return since it was even more difficult to climb down. Means no more Phantom for now. I wait now what coming out in the next time.
