Just google it. There is a website for JetCat. The largest engine makes 47
or so lbs of thrust. Two of them would be perfect for a self launching
glider. 4 of them slung under the wings of a Blanik like a 707 would be way
cool.

IF they had a decent hours before overhaul, which is a big if, indeed, you would
be only a novelty. Those small engines go through fuel so fast, that the plane
would need to be as big as a 707 to carry enough fuel to really go somewhere!!!

Well, not really, but you get the idea.
