Update Jan13th, 2015. Well, I'm up to three lost motors. Not sure if the 900 mah battery is the culprit or not. Now awaiting another 4 ordered. That makes 6 motors total! Granted, I fly it harder than a beginner would. If you wish to purchase this quad, do so while ordering another 4 motors. This may become another V262 motor eater. Brushless motored quads from now on. They are fortunately becoming more economical.
Update 1-23-2015: Banggood informed me they are out of stock of the H8C motors!!!! My conclusion.. Avoid this quad!!!!
