I have the NOS motor in my zipzap too, but the Black Celica 2.2 Microsizer kicked it's can all over the place. I havent raced the auto modellista against the celica yet though. they have the same motor, but you never know.

Btw, both the microsizer and the auto modellista bit-char-g are 27Mhz, but the controllers do not control both cars. Do you think that 27 Mhz in Japan is different from 27 Mhz in America?
