I am a newbe to RC and am getting ready to buy a Thunder Cat RTR boat. I have been seeing a lot on this site about all sorts of radios and issues. Is there a radio 101 thread I can read. Basically it sounds like there are AM radios, the "old" FM radios and the "new" FM radios. I am must interested in the farthest signal distance to control the boat and features is secondary. Anything and everything that it would be good for me to know is solicited to include makes and models of radios.
