I know that most pros do run stock motors but the one that I am not so sure about is Drake. It has been said time and time again since he went to Nova that all of his motors are special factory modified versions. Do I know this to be true NO, do I believe it YES. Drake consistently get more run time than everyone else on the track. If it is true than that means that even the factory can improve on their own design so why cant another experienced modder who understands the complexities of these tiny motors do the same thing?
