Unfolding stock 2.4 (left antenna) until it clicks in first position which means when holding transmitter normally for flying its vertical, and the video mushroom right antenna in the same angle as left antenna, now I have flown totally everything stock including the original EU firmware across open field farmland at 200ft altitude and a distance of 5384ft, and still a strong video connection the only time I briefly lost video for a spit second was when I turned around to come back on its way back after approx 100-200 ft travel distance, it regained contact immediately and I raised the altitude to 300 ft just to be on the safe side, since I carried this distance test my H has been back to Yuneec CS for some other issues, and because they also updated the firmware whilst they had it I've no idea if I would still get the same excellent results, as this distance is not within los I wont being trying again it was more a case of assurance and test of the video signal.
