OK guys I am new to the hobby and just ordered a CT4S with the Porsche body. After reading this forum all last night I also ordered the tensioner CT028 and the Drive Terrain upgrade CT045. The only thing that concerns me is that I have to be careful where I use it. My friend and I are going into this hobby at the same time. He ordered a Jato so I was thinking we wont really be able to have fun together because his is an off-road car and mine is strictly on-road. Thanks again any suggestions or tips?
