Yeah, AW should have done a can motor based inline along the lines of a Tomy Turbo or Tyco HP7. At the end of the day, the Turbo and HP7 are about as plug-and-play as you can get for newbies who have a passion for speed.
I think AW tried to emulate the Wizzard P car without having someone with the technical expertise and experience to deliver on the promise that the Super III design implies. They could have sourced a cost reduced chassis from Wizzard, BSRT, or Slottech and come up with a body mount that adapted to one of those chassis designs. The value in the deal for AW would have been the AW hardbody.
