Traxxas is the number 1 RTR (Ready To Run), if I'm not mistaken, and for a reason. Fairly priced and very durable with a great parts supply from most hobby shops.
I race Losi cars and trucks but my Traxxas Nitro Rustler is the best I have for running in the parks, at schools and just all around bashing. I've never had to order parts as they are all readily available at my local Hobby People as well as other hobby shops.
