A few day back I got an Airtronics Park Flyer receiver, you know the kind with only one antenna. I asked my boss what he thought was a safe range for this kind of receiver and he told me about a 1000 ft. I installed it in an old R/C plane I have and took it out for some testing this morning. All went well it had enough range to fly my plane like I did with the previous full range receiver. Anyway does a 1000 ft. sound right, that's over three football fields in range which would put the plane way out of my comfort zone for the kind of flying I like to do.
