I just had the EXACT same thing happen to mine, and on the first flight no less. Launched it, made about four or five circuits around the field. I noticed the motor coming in and out, so I throttled down. About a minute later I was at full throttle and it happened again, then the plane went crazy. I chopped the throttle and tried to pull up in a last ditch effort, but it was over. The plane dissapeared behind some houses and then i heard the impact. Plane and lipo were both a total loss. I was flying a gws 4 channel receiver which I am blaming at the moment, but I also suspect the esc may have had a hand in it. Can I buy a replacement airframe? I know I remember reading about one for around $70, but I can't find it anywhere.
