Because Trinity isnt a producer.Ernie is the Bill Gates of the RC world.They buy smaller companies to produce there parts.Look at there aluminum parts,they are made by someone else that he made a deal with.Now he has Nova motors.Smart man I just hope it comes back and bites him someday.I will be using RB,NovaMega or Mugen motors from now on.Its good that you can get Fast tires thru Mugen.
Has anyone noticed that Trinity is always in favor of foams instead of rubber? They do not make rubber tires!
