I got a complete Traxxas Tmaxx for sale..it has the 2.5R in it, along with the 2.5 stock motor in a box. It has a box full of misc parts for it, truck has roll cage on it and other upgrades. I don't know much about Nitro Rc's except how to start them and crash them haha. I have drove my truck twice and I want to get rid of it as it's too much money for me to break. I'd rather use the money elsewhere. But, If you are looking for a whole complete truck, I'd sell it to you for a hell of a price.
