That is a nice looking chasis but the thing I hated about my original HPI RS4 was that little rocks a little bigger than grains of sand were getting into the drive train. They rattle around until they caught up in the drive belt system. They would shred the belts and tear up the pulleys. It agravated me to no end when I would rip the car apart, replace the bad belts then re-assemble the car and then watch it get torn up within the next runs. That is why I invested in a HPI RS4 III SS (Nitro shaft drive) after the engine blew up in the original car. I bought a Team Associated TC4 (Electric shaft drive) for cleaner runs.
