I know others may not agree with this, but i have had really good luck with a Traxxas Slash 2WD many times at skate parks and drained pools. Even when it did break, it was minor things like lower arms. As for Arrma, i started with an Arrma Granite, that i eventually turned into a Senton truggy, and every time i ran that on anything concrete with jumps, it would constantly break. Even my Losi 22S SCT broke way less than my Arrma build did. I think the reason for that has a lot to do with weight. Arrma's 4WD stuff is a lot heavier than a Traxxas 2WD, so it seems like that extra weight translates to harder landings. The only time i found the Arrma to be somewhat durable, oddly, was in the winter in snow. The Slash was also way easy to flip and do odd stunts with, whereas the Arrma was harder to even do back flips with. In one instance with the Arrma, in the middle of summer, i jumped off a roughly 4 FT. drop, broke both lower control arms, the left upper link, blew a shock, and destroyed both front hubs. In one year, I had more money tied up into constantly repairing my Arrma, than i spent on both the Slash and 22S SCT, although, i did buy both of those used.
