I recently won an Aerobeez Stinger in a raffle at a fun fly I attended. This thing comes without any documentation, but they do have a set of videos at their web site for assembly. Anyway to make a long story short I flew it this morning. I forgot to dial in some reflex into the elevons which lead to a very short first attempt. After dialing in the approximate reflex (it looked good to my friend) I attempted a second flight. This time things went much better, at least until the motor shut down. At first I thought the problem was a dead battery, but no. Then I thought it was the ESC, later I discovered it was both the motor and the ESC. It seems the "C" clip that holds the prop shaft/bell to the stator bearing came off. When this happened it jammed and because I kept the throttle up the ESC smoked. Given the very small size of the "C" clip I elected to toss both the motor and the ESC. I have since replaced both with some spare parts I had lying around. It really does make you wonder about the quality of the stuff we are getting from China, some of it is just plane junk with a capital "J".
