Frequency selection is really a personal thing. It usually has nothing to do with location, and definitely has nothing to do with type of plane. Any of the radios out there will fly any of your models on any frequency (within the limits of available channels, of course). Some will say that certain frequencies might experience more "hits" than other channels at particular fields, so you might want to check that out before you pick one. Other than that, go through your membership list (if its available), and pick a channel that the fewest other people are on. Simple as that, really!
