Excellent, comes with brushless esc built in. Great power system for small planes.

This was supposed to replace the motor on the YLR/C S99 Drone I had purchased earlier, and the motor quit on the 4th flight. It works well, however the "leg" of the housing is longer than the original. I had to take both apart and switch the housings to make it work. Also, the plug is a different color than the original.
It did arrive safe and sound much earlier than first expected. Banggood kept me up to date at each phase of the shipping process.
