I honestly believe that not having to invest in expensive tools like a dyno and mag zapper brushless has evened up the palying field in the motor area....
I know it more then likely has some guys mad as hell because they spent a shit load of money on brushed tools and equipment so they could have a edge over the guy that was fast but didnt have the $$$ to throw brushess and springs etc to get a killer motor..
And it has actualy made some guys faster because by not having the fastest motors they worked on CHASSIS set up to make them faster and now with the motors being equal it in some cases has given the edge to the guy that has had to use his chassis skills to be fast
