K80 MOTOR BUlLDERS
I have compiled a list of motor builders that I have either had personal experience with or have run against at an event.  By no means are these the only builders out there just ones I have seen their work.  The list is in no particular order and reflects no kind of ranking...just luck of the draw.   Be leery of builders who guarantee to put you out front, without knowing your competition and your situation it would be an empty promise.
