RE: Ever had a problem when swapping crystals?
I am not sure if it is illegal or not but I know it is not recomended. However, for two years I have been flying one module tuned for 45 on 54 as well. I have never had a problem, I have probobly swapped that crystal in and out 1000 times. But now that I am moving into more expensive planes I am buyig two new modules tuned to the channels I like to fly and will swipe modules not cyrstals.
