It looks like the fire damage on the roof of the plane is right above where they keep the rear battery.. The battery is kept below, so, I'm not sure if the fire could spread to the top of the plane. This would be very embarrassing if it's the battery again. They were suppose to be replaced with safer, fire proof cases and other improvements. After dealing with RC lipo batteries, I can say they are real difficult to charge and keep. I always assume they could catch fire at any time. Really not the thing you want in a plane.
