Simple question I have been dong some line of sight testing since getting the phantom as I have a golf course that I have permission to fly over as long as I dont piss people off late afternoons. I am still yet to loose radio reception but always maintain direct LOS to the phantom at all times, last flight measured on google earth was 925m away from me with altitude 50-75m I would guess so that would be very close to 1km from a stock radio. I need a bit higher altitude as there are a few big trees on my flight path I have to clear and the further I go the higher I need to get to maintain LOS above those trees. I think thats pretty decent as the rated range of the stock radio is only 300m, I am getting a FPV setup in the next few days and will be interested to see the range I can get out of that. I am using a screen rather then goggles to help try and maintain LOS as much as possible and I will be interested to see what range I get out of the DJI avl 5.8 500mw setup with DJI antennas. This setup should be able to easily match the DJI radio and I really dont need much more range then that anyway I think mostly using the phantom and FPV to improve video framing and do some more fun flying at closer range. As a part 2 of my question what sort of range are people getting from other radio's? distance and model of radio would be good to see what would be a good upgrade choice if I ever felt I needed more range.
