2.4GHz doesn't use crystals to define individual channels. It uses spread spectrum techniques to avoid interference which also allows it to co-exist with other 2.4GHz services such as wi-fi. It works very well as we have had probably 20 transmitters clustered around one arena with no noticeable interference problems.

You have to "bind" a transmitter and receiver together so that the receiver knows which transmitter to respond to. This is a bit like linking bluetooth devices (also on 2.4GHz btw).

You do have to make sure that both transmitter and receiver use the same protocol so that they can bind and work together. DSM2 is probably the most popular. Originally developed by Spektrum, there are now a number of "DSM2-compatible" devices available. Although there is no guarantee of just how "compatible" various transmitters and receivers are there are several well-known combinations that do work and as far as I know problems are actually quite rare.

The latest protocol is DSMX and many receivers are DSMX/DSM2 compatible, but make sure that whatever transmitter(s) and receiver(s) you get you always get matching pairs!
