This copter was an awesome Christmas gift, that was given to me back in 2012. It was my first copter and proved to be very durable.
Unfortunately, at first the copter was rather disappointing because it wouldn't get off of the ground and was going through batteries way too quickly. Upon inspection, I found that one of the motors was getting hot. As shown in the images below, I was able to replace the bad motor. With the problem solved, the copter provided countless hours of flight.
