One more note:
Wherever you decide to fly, it is considerate to make sure that there are no Clubs within a couple miles of where you plan to fly. Sometimes Planes go down at Clubs, and the Pilot swears that someone using the same frequency has turned on thier radio. Parkflyers who may have been seen flying nearby at some point in time often get the blame even though I believe that 99.999999999% of the time this is not the case. Especially since alot of park flyers don't even operate in the 72mhz FM band, let alone on the same channel. The ParkFlyers that do use a regular 72mhz FM Air radio usually have the same radio for both there electrics and their gas Planes, and I would say most, but not all belong to a club.
