Hey GUys,

Just a little introduction:

Went to the field today and spent four hours trying to come up with a reason not to pull my hair out due to engine failures. I only got one flight in the morning and while my plane was vertical during a loop, the engine shut off. I landed it and we took a deeper look. WE started the engine and we held the plane vertical, the engine shut off! WE took out the fuel tank TWICE to see if anything was causing this, we found a slit in the fuel line, but that wasn't it. It's the engine. IM taking the engine apart and i would like any information or tips on what to look out for in an engine failure like this.

When my engine is in a vertical position, it shuts off. Why does it do this? Its not because of the pressure failure in the fuel tank, there was a slit in the fuel line, but its fixed and still, the engine shuts off in vertical position. I think its a leak or a loose screw, and I'm taking it apart, help me. What do you guys think?

Thanks alot,
