I recently purchased this plane:

I installed the following Motor and ESC for it:

As I fly it, no more than couple minutes the plane started to lose power. I look at the motor, ESC, and 6S 4000 mAH Lipo that I used was hot. What happened? If these aren't really the right motor/ESC combo for it, then what motor and ESC is perfect or should I use for it?
