read all about the features of the 4YF radio here

Now available in either 72Mhz (Aircraft) or 75Mhz (Ground) frequencies! The FCC regulates that you CANNOT legally use 72Mhz systems for ground-based vehicles, but we get a lot of requests for 72Mhz systems for those of you flying model aircraft. Now you can purchase this system on the 72Mhz frequency from us as well. PLEASE DO NOT attempt to use the 72Mhz system for a ground-controlled robot! When you buy the 75Mhz ground system, it is configured from the factory specifically for use with ground vehicles such as robots or RC cars/boats. When you buy the 75Mhz 4YF from the Robot MarketPlace, it will come configured without servos (you don't need those for your robot anyway, right?)
