Yes, to a certain degree. Aircraft people make a bigger deal out of it because glitching can mean losing your entire craft. It's ALWAYS a good idea to have your radio tune by someone that knows what they're doing so you get maximum range out of your setup, but weather or not you do is another story entirely. If anyone ever tells you you're a Satan spawn for swapping crystals though tell them bugger off.
It's not a question of Satan's spawn. It's simply illegal to change the crystal in a transmitter in the USA without sending it back to check the tuning
Now, whether or not you obey this law is, of course up to you but remember please that other people want to continue flying, and don't want the authorities coming down on us all.
We share the 72 band with some financial heavyweights (and, in fact, are secondary users of those channels) who could easily make it difficult for us all if we show we are irresponsible.
Also, it's done for a technical reason, and isn't simply a matter of range or glitches as you put it.
