Hi guys today I flew my pv2 . It was in a wide open area and I had 10 sats and flew without problems. I then lowered my altitude and she flew lower than where I was standing as I was on a hill. I then started to lose contact and it eventually landed in a field not to far from me maybe 70 meters away . So I guess the signal doesn't like to go below the remote? Is this normal ? Cheers Dave.
