I've tried a lot of different radios on these tanks and I have found that if you have no additional accessories, like volume control or a notek light or something then all you need is four channels. The HobbyKing T6 is about $25 and it's a 6 Channel radio that will run these tanks just fine. If you're looking for the lowest cost that's the way to go. Erik has a tendency to like the high-priced radios because he does a lot of flying and he needs way more features than you do for a tank. Right now my go-to radio for tanks is the FlySky i6 because I like to use a Viper for volume control and you can set one of the other switches for cannon fire. The I6 is an extremely easy radio to use and program. And, it's not a bad cost. I don't know about the real FlySky but the Turnigy version goes for about $50.
