I have the hyper 7 with an axial .28 spec 1s mounted in it. And I tell you, you won't find a more durable buggy. Yes, I have several upgrades on it, such as carbon fiber upper plate, and aluminum throughout, but still, I have beaten the ever living crap out of it for several months now, and ( knock on wood ) I haven't broken one single part on the whole buggy.....seriously..... I would put my hyper against any of the more expensive brand buggys out there, and I would be more than confident that it will out bash all of them.....
