Sorry, BLE, but someone does care. This not something to be cavalier about.

If someone comes to our field with a pirated transmitter and we find out about it, well, that person won't fly at our field again. It's not what happens, it's what could happen. It probably doesn't matter with cars, or boats, but with airplanes and helicopters, it does. Would you like to fly around a person that has a transmitter that you know he has messed with? How about if you have a crash that you can't just figure out and you find out that some character showed up with a transmitter that he just swapped out the crystal and caused your problem. You may never find out, but you may. I know what I would do, and it would be costly to that character, I can tell you that.
