Be warned- GM's warranty service is sub par for how much those things cost.
I had a Worlds V12 go out on me and sent it in to Horizon. They wouldn't replace the bad board- they only offered to replace the whole ESC for $155 which is a joke since you could buy them new for $180. Atleast Novak and LRP offers half price replacement cost assuming the warranty has passed which is lifetime with LRP.
Just my experience...
