Vince,

Don't know exactly what caused the fire. There was some smoke coming out of the tailpipe after the deaqdstick landing that looked like residual smoke oil in the pipe because it was white. Then as I got closer to the plane the smoke turned brown then quickly black as the fuse started to burn. Don't know why the flameout either. That's the problem with fires, they tend to destroy most of what you need to see to determine the cause unless you're a fire expert. Which thankfully I'm not and don't wish to be.
