Ok I am not new to the Nitro Rc I currently have a LST with a LST 2 motor, a Muggy, Tmaxx with a 2.5R motor, and a Revo with a Max .26 Picco, I just bought me a RS3 18SS and just started the breakin what is normal temp for the break in, I noitice the engine is alot smaller then most of my trucks and was wondering if the HPI would run hotter, also I am looking into maybe wider tires,rims because i can tell when the break in is over it will be almost impossible to control unless I get more traction......
