I've just got back from my first range test on the edge of Dartmoor after switching to FCC 2.4.
I launched the poor thing into a force 4 headwind and managed 1250 mtrs before I started losing video signal. First time I've flown it out of sight (had my ground crew (mrs) at the the other end as a spotter).
A rather unnerving experience especially as I had a screen full of warnings by the time I pressed RTH.
At least I know its not going to drop out of the sky if I fly it out of my local rec.
