I just wonder, how they gonna know what power you are transmitting? They must have a special receiver with a "S" meter, and even then a good antenna will give the impression of a higher power. At 2.4ghz (line of sight) is it going to help for an extended distance? Is 27megs still available for radio control, if so one could go further. Just a quick calculation, 30 minutes air time, speed 50km/k, if you want it to come back use 20 minutes, so you can travel a total of 17km....8km there and back. Even 1w isnt going to help? If you went to 27megs you could go to 10w, maybe then you could get that distance.
