If I had a company that primarily sells brushed motors, I would invest in the development of a load dyno instead of just a RPM checker, besides taking out full page ads about why ROAR !! I don't know if it's just me or simple logics. If the average racer have more toys to thinker with and help them tune their motors (which are inferior to the ones that team drivers get if i might add) they would be more inclined to run brushed motors. I must say; some of this logic is panning out with the introduction of the spring thing ( another copy of the fiddle stick/speaking of a copy; 30 Amp pulse discharger) We could only wait and see, but where there is a demand someone will capitalize on it. That's one of the things I LOVE about this CAPITALIST country.
