Hi Paul,

Thanks, I didn’t expect an answer so quickly. Aren’t you wrapping it up at SUN & FUN today?..

I am interested in building an up-dated 1/2 scale flying model, or a proof of concept single place engineering test vehicle.

Possibly an ultralight or another aircraft that could prove out some concepts and configurations.

I expect that you have a lot of thoughts on which configurations are really efficient. Can we advance the design or designs ?.

In 2001 Roy Lopresti (my former partner) in LOGO, introduced me to one of the Navy test pilots that test flew the VTOL’s

In the 50’s. Roy was the Air Force Test engineer at Wright field at the time those tests took place. He really shared some

wonderful and interesting insights into flying a VTOL.

After 12 yrs. off the project. I’m ready to dust it back off and revalidate the concepts and designs

What would you like to see done. And where are you located.

The video’s and patent references are 10 yrs. old but they demo principals that did work.

That is all well and good for hover but ducts are bad for high speed forward
motion. The drag of the duct far outweighs the advantages.
Perry Mick tried for years and finally gave up and put a gear box and prop
on it and went 30 or 40 MPH faster on the same fuel burn.
