I built a Tamiya R/C one time. It was very easy, the direcetions were really good. Mind you I was probably 10-11 when I did that.
I bet you could put that together with only glancing at the directions a couple times... Tamiya R/C's are very easy to build.
And, I'm sure you know, but that is not a model... It's a good quality R/C car.
$300 is a deal for that. New, from Tamiya, I think they are around $4-500.
