It does indeed come standard, my 450 SA came with it. Unfortunately, from that little test, it seems to draw a lot of current while producing only mediocre results. Dont get me wrong, I plan on flying the hell out of it but it definitely leaves some room for improvement. Of course, it was in some pretty esteemed company, Medusa, JGF, etc all are top notch motors and it sure shows in the numbers. JGF 450th might be in my future...
