jeez all the flap and still nobody has told him the sweet buggies
The highest quality kits on the market are the kyosho, mugen, and x-ray.
They are also the most expensive. If your just bashng, i would look into getting a used Mugen MBX-5 or a kyosho kanai. They are both extremely tough and given the trucks you are running now, you will be amazed at how tough they are. I got clipped in the traight away lst weekend and my Kanai III cartwheeled down the track over 50', flew into the next lane, and got smoked my an oncoming ofna hyper 7. What broke on my car? Not a damn thing. the ofna broke an a-arm and the steering ackerman.
