So I was flying my Trex 450 at a wide open soccer field the other week. I was practicing upside down hover and got a little low. I thought I could pull out of it in time before hitting the 4ft high fence behind me. I thought wrong. Clipped the top of the fence. I have yet to assess the carnage.
I always find it amazing the magnetic pull of the lone tree or the fence behind you has.
they're like black holes.
