I'm willing to bet that over 80% of our RC pilots on the airfield I fly at use Hobbyking stuff, lipos, ESC's, motors and all. The same is true of most of the RC offroad racers in the Truggy and buggy cups 1/10 and 1/8th scale. Most run either Gens Ace or Turnigy, and that is mainly because Zippy has only few hardcases at the moment which are mandatory at the races.
