I found also part for FORD 9"dia and 3 to 1 ratio but much
 stronger

 On second thought this is not such a bad idea.
 What do those parts weigh Jean?

 Do you know of a NC machine shop in Florida that can make
 housings for you?

 Also what is your budget for shafts and gear boxes?

I'm also interested in the 3 to 1 part number.
Have not received reply from Tracy Cook on PSRU.
May have to build my own, or be part of project.

Are you also going to use two engines in a pusher arrangement like
this?
BTW Jean your rotor housings are in.

Any idea on the tail volume? If it's at the wing tip's I think they would have to be huge?
Using an extended empinage you could get a vertical back there which might do the trick..
I'd think it'd be pretty tough w/out extending back a fair ways?

Interesting design none the less!

That is one reason Ruttan swept back the rear wing.
That and for CG problems.
