For bashing I say stampede 4x4.brushless of course. I won't recommend the velineon system tho. Just not a fan. But if you are really wanting waterproof try the hobby wing wps8a.is waterproof out of the box and under 100.is 2 to4s capable. I own one. In my stampede now. Beast of a controller. Never had a great issue even when running my mad beast (savage xl clone)on 4s.
