For the most part, FM is a cleaner signal. Think of your car radio. The FM stations come in a little clearer than the AM stations, and are less sensitive to outside interference. In RC cars, the power output is nowhere near that of a radio station, so it is a little easier to interfere. Some construction sites and buildings may cause interference from radio signals "bouncing" off other objects, Alarm systems or other in use radio systems. Hopefully the release of the 2.4 Ghz modules will fix these problems.
