I have a 2.4 GHZ tower (wireless internet provider) about 400 meters from my 37 acre field. My old Phantom 2 operating with a 2.4 GHz controller can fly with no problems what so ever around this acreage, never once with a loss of signal issue. My new P3 Advanced with two antenna had no end of issues in the two shake down flights in this environment from loss of contact, compass errors, GPS loss. I won't fly it here again, can anyone with experience tweaking channels a bit to avoid noise comment? It amazes me to see people fly their P3 systems long ways over urban environments containing I'm sure a lot of noise on the 2.4 GHz bandwith...this is a big cause of lost UAV's inmo.
