Not to start a fight, but I think it is funny the Losi and Associated guys say that the slop makes the cars better. Losi guys say that losi's are "Loose" and Associateds are "sloppy", then vise versa from the Associated people. None of my Losi's got "Loose" or "Sloppy". Take care of the car and ream the arms and the car will be bueno.
Mugen or Losi. Both are good, but I like Mugen.
