As for HobbyKing i think you get what you pay for, most of the stuff i've ordered from them has been ok apart from an Orange 2.4 RX which worked once when it was bound to the TX and then nothing. It would cost more to send it back than the RX is worth, so its a bin job.
And that's the story with the small electric motors and ESC I bought from HobbyKing. One motor was bad out of the box. The other one wouldn't work with the ESC. The ESC worked up until a couple of weeks ago and went out in flight.
Cost more to send them back if there was confidence that would get a refund.
Done with HobbyKing.
