Default Crystal swapping

I just purchased a futaba super 6 on channel 35. My current plane is on 60, a frequency that is normally free at the field. I'd like to put my current crystals in the new radio and use it on channel 60 but I'm not sure what effect this would have on the radio's "tuning." A friend said you shouldn't swap the tx crystal since it's tuned, but is the tx tuned high and low like the futaba receivers are, or is it tuned for one frequency. If it's tuned high/ low I should be able to swap crystals for any of the lower frequencies shouldn't I? Or is it safe to change to 60?

You legally can't change them period. This threads been beaten into the ground, and a thousand people will tell you it's fine, and a thousand others will tell you it's evil. But just on general principals you should take it to have the transmitter crystal changed. If you don't want to don't. Not sure if it makes any technical sense, I don't know about the notch filters in these radios, if that's what they're tuneing. The whole reason is to avoid harmonics spilling out into nearby channels.
