How far will the frequency ranges listed fly your model? Far as you can see the attitude of the model. This can change depending on the size, type and shape of the model, but seeing as you can't actually see what the model is doing regardless of the foregoing beyond about 1/2 mile, and the radios have an airborne range of several miles, the absolute range of the equipment is of no practical interest other than the range of most modern radio (park fly stuff excepted) is 'adequate'. If you don't know what the model is doing, you can't fly it so 'range' is only what you can see.
