About 20 years ago, I was big into RC. Back then, there was not much choice in radios. I always had my trusty Futaba Attack. Now things have completely changed. Could someone explain or direct me to a site discussing the differences between AM, FM, 27Mhz, 75Mhz and DSM? Right now, I own a Losi Mini-T and am dissapointed with the range. I am looking at getting a RC10-B4 and want to get a decent radio. Nothing too pricey or exotic. Just something with a decent range.
