I haven't tried it but I was JUST reading about jets out of curiosity. Appently they do this kind of stuff all the time. Take a look at this site:

These fuel systems were designed to work with ducted fan and turbines. I would imagine that the muffler back-pressure of a ducted fan engine would be similar to that of a conventional glow engine.
I don't know enough about it to say if it would work for what you want to do, but I thought I'd pass on the information anyway. Hope it helps.
