I went the same route and started with a 4 channel and then got the futaba 6xas. As much as i like this radio im kind of disappointed with it. I just got my first Heli and the programming for it is very limited. I don't think it will be long before i end up with a more flexible radio. I say if you get a good deal on a futaba 6x then get it, but if your planning on buying new i would highly recommend to get the best radio you can afford or you will be buying twice just like me.
