and for the purple stuff that is NOT on the kit verson i think it has somthing to do with the team drivers such as hara when they made the parts they wanted purple. also the black parts on the kit are NOT plastic (i am pretty sure) if they were plastic then 500 for the kit would be a big rip off. as i stated a few posts up i think it might be a way of creating a hop line for the car so they can make a little extra money or they wanted to keep it black so they could later come out with a Hara verson later that would have all the purple. lastly it could be because the black "stealth" look is becoming a pretty popular as people are starting to put all black wires on their esc and things of the nature.
