Greetings...I have 5 t-maxx's and need to repair one of them. It is a 2.5 4wd and one of my sons drove it full speed into a tree. My question, I have a Spektrum Dx3r with a SR3100 receiver and want to convert the maxx to 2.4ghz. I can only imagine that it wont be as easy as just plugging in the receiver and binding. I also need to figure out how if possible to assign a switch on the Spektrum tx to go from forward to reverse. Suggestions and ideas are appreciated.
