Hang in there Rusty. I got some of the same in the early days, having
a ducted fan and a rotary engine. I may eventually go PSRU but I will never
go Lycoming! Love that rotary. I think I'm accumulating more hours than
the trainers on the field.

Thanks Perry. Say, I've been meaning to ask if you've
ever looked into the Jet Hawk. As I'm guessing you know, it was a jet looking
ducted fan design that used a rotary engine. These were advertised quite
a bit years ago, plans were sold, and a few were completed, but it's my
understanding that it didn't perform that well. I guess it used a simple
homemade fan, that didn't work very well. I tried at one time to buy plans,
but never found anyone to sell me any. I'd probably still buy a set if
anyone has any. I understand that there are some fan units that would make
the plane work, but the fans are about $10k.
Cheers,
Rusty
In 94 I got the idea of using a rotary to drive a ducted fan. Information
was scarce. It wasn't until 97 that I found a book for sale on the internet,
"Ducted Fan Design" by Marc de Piolenc. It is the equations in that book
my ductfan was designed to. There is an example in the book, where Marc designs
a ducted fan to improve the performance of the Jet Hawk. That was the first
I had heard of the Jet Hawk. So my knowledge of it is limited to what I've
read in that book.
