I've seen and heard many a feigao motors bite the dust from over heating and rotors going off like a grenade. You get what you pay for! Only problem I've ever had with my Neu motors is having to replace bearings. Going with a cheapo motor is like going with a cheapo speed controller. "Zero" customer service. I called Tekin about a replacment rotor for my T8 that had the magnets come unglued. I got to talk to an american customer support person and had the rotor in the mail that afternoon. I'll pay for a Neu anyday over a feigao clone for my big rigs.
