I crash this bird due to left turbine flame-out later.

Glad to see you found out what caused the crash, but what caused the fire?

After that crash, I checked the remain then found the fuel line and fuel tanks were all OK without any leaking. I didn't use by-pass in my plane and the foam/glass belly hatch of ES seemed be ignited by the right turbine that still working in full power when crash.
