RE: Free EXTRA 300S from ********.com BUILD!
Looks like all you need is a male dean's connector and you are all set. From your pictures the motor has the ends you need to put on the ESC (pull off the small gold thing's on the end of the motor wires and solder them to the ESC and use shrink wrap on them). The attached picture is what you will need and what it looks like when completed. If you havent soldered before practice before you do them as a poor solder joint will fry the motor & ESC and possibly the battery.
