What you really need to ask yourself is this. "Does my airplance cost more or less to replace than the 25 dollars I'll spend getting the correct crystal installed and my system tuned correctly?"
nope, that isn't a problem. the question you REALLY want to ask is how much is the 25% extra the guy next to me flying worth, after it crashes due to my out of tune radio spattering the frequencies...
