Problem with Traxxas Nitro Rustler
 

Hi
Ibought this nitro rustler brand new last week and Idrove it on the grass with no problem. 1 week later, it doesn't move a muscle on the grass, even when Igive it full throttle. It's fine on the street, dirt, rock.... but not the grass. My question is do Ineed new tires ? If so what tires do you recommend ?

Sounds like your slipper clutch might be waaay too loose or maybe a stripped spur gear that is still rubbing just enough to get it to move on surfaces that have less resistance. Also if its brand new I hope you did the break in procedure before you were hammering on it full throttle.
