These are a nice budget radio from Spektrum, although I'd like to see some sort of a menu system with digital trims and at least a big enough memory to store a few models. BUT, I guess their answer for that would be the DX3S or R, you gotta pay for those extra features!
I predict this will be the new RTR radio of choice for many higher end vehicles coming out. Either way, the reliability of Spektrum 2.4ghz is worth the $100 alone, I HATE interference!
