I think something can be arranged.

The engines are manufactured by a company in West Virginia. They have
multiple uses, models, target drones, and such. Each produces 45 lbs of
thrust. Not really much, with the standard reciprocating engine set-up
on the Ascenders we get over 200 lbs of static thrust, so it's more for
the idea and the sound than it is for performance. The only thing is
that a jet continues to produce constant thrust, regardless of speed,
while a prop, once it reaches a certain speed, cannot produce more
speed. Has to do with the speed of the screw (basically what a prop is)
through the air.

Neat things. About 12 inches in length, 6-7 inches in diameter. Very
light. Expensive, $5,000 per engine, with a TBO of 50 hours.

My friend Jack McCornack produced the thingies that were in the last
James Bond movie. Basically a set of wings that a sky diver can strap
on. Once free of the aircraft, the wings are used to extend the glide,
and can reach speeds near 200 MPH. Jack thinks that with the 2 jet
engines the device can maintain level flight at 200 MPH, and fly
formation with a slow flying F-15. Note, he likes the notoriety of the
credits in a movie. He thinks that the next Bond movie might use his idea.

Stupid, still have to deploy a parachute to land. Not for me.

Anyway, he just left for the Oshkosh flyin with the engines and my
2-place training aircraft, which flew with them last year. When he
returns in a week, I'll be flying the 'jet (under) powered ultralight',
I'll take some pictures, and try to get them on the web.

Are we off topic yet?
