I am a die hard fan of Traxxas as the parts are everywhere. For the most part they are strong rc cars, especially for young kids. I have four daughters whom all drive my Traxxas rc cars. They are not allowed to drive my Tamiya's until they show me they are mature enough to, but they drive both my Traxxas though. I have the 2wd slash brushed and I have the 4tec 2.0 brushed version. I was hesitant at first with the 4tec, but they got them both out there and bashed them both and to my pleasant surprise my slash was the one that needed a new front hub carrier thingy. No big deal all, as the part was ordered via the Traxxas app, but it was also at a store which is 20 minutes from me. The other thing that broke before that was the front under chassis crash bar thingy that protect the steering servo stuff. No big deal either. Anyways if you dont like what Traxxas has to offer, I was not too happy with their chassis at first, I recommend Arma. There cars are built stronger than Traxxas, but sold at a lower price point. The quality is not less, just the price. I honestly have to say the quality in the engineering department is actually better than the Traxxas. My next RC car will be Tekno as they, from what I have researched, are all assembled with parts sourced from with in the USA. I have not read anything otherwise though.
For bashing, I would research for a really over engineered RC car. the kids love the biggest tires possible. With big tires come bent hinge pins, hub parts...basically anything on the car that could get slammed into mailbox colomn, telephone poles, curbe, car tire bumper. All that stuff rips rc cars up. So yeah look for not so much a monster truck but a car with big tires and over engineered suspension parts for strength. This was why I like Arma. If you really want to invest some money and you want a car the kid could grow for a long time with, the extreme series by Arma are pretty heavy duty, but th speed is not child tuned and the price might turn you off. But for just something to blow up slowly in the cul de sac or neighborhood court/street, then Traxxas will be great
