I have been observing the car adds and chat pages, and I am wondering is the radio (TX) the least and lastof the items for a NewB. What I am getting at is that there are a lot of RTR out there, with tons of info on the car. Yet there is very little on the TX, would you be better off getting the car and then the radio of your choice? Is thr RTR combo (T MAXX) radio any good, or is it just a genaric brand bottom of the line. Thanks Buffaloman aka Frank
