Paul,
I listened to you at the Rad Cam booth.  They were making all kinds of
promises about there new motor, and to me, it looked good. But now they
are ?  I don't hear a thing about them.   They were saying they almost
had this and almost had that?  I am in need of 170-180 HP and willing to
do most anything but full blown experiment with motor.

We have full machine shop, 25 years cad background and so on. I build
the Patrols.  Perhaps the strongest-most efficient super-cub style
aircraft on the market. HP for HP we get 40% more cruise speed... and
exactly the same landing speed.  A great plane, in search of a great
motor.  I was at one time thinking the Rad Cam might have been it.

Any others out there that are able to deliver on their promise's?

the Rad Cam I mentioned might not have been the right name.   What I meant was
Rotaryae by Nathan Oldham  the site is not providing info...so am guessing is
defunct?

Scott, I have known Bob Barrows for years. I see him at a lot of airshows
like Sun n Fun, Arlington and OSH over and over again. Great aircraft engineer.

We have several Bear Hawks being built with Mazda Wankel engines.
A Super Super VTOL Cub would make good PR for your company.
You can get a 2.85:1 gear box from Tracy Crook and use 7500 engine RPM
with a 76 inch prop for take off with an all aluminum 250 HP P-port.
The Tracy gear box is based on a bullet proof six pinion planetary gear set from
a Ford diesel pickup auto tranny.

Firewall forward would be another 100 pounds for Tracy gear box, exhaust,
rad etc.,etc..

Real easy to build P-ports if you have a mill and can tig weld.
