And still I believe that brushed is still a way to run a stock competition, at least over here some Tamiya races are done with the Carson Cupmachine which is a very good motor without a huge spread in performance.
Racing blinky BL stock is always infected with cheats like shifted sensors, illegal motorparts, illegal software or a modify that the LED is always blinking. People are always saying there is nothing wrong but sadly there is too much of this going on.
But that is my opinion.....
