Hello all, I'm a newbie to this hobby. I picked up my first rc car/ first nitro this past weekend. I got a Traxxas nitro sport setup with the .15 engine in it. It seems to be haing problems with the clutch. It starts up and runs good, as soon as you place the rear end one the ground it won't go. When you can get it to go it runs fine. When you slow down the clucth engages or something and it doesn't want to go again. Do i need to just put in a new clutch or is there something else that could be going on with it?
