John,

Basically Ed said the same thing as you. As long as I wasn't doing anything ground breaking, ground testing wouldn't help me with anything people on this list haven't already worked out themselves.

Cooling does seem to be the bane of Rotary fliers, and even more so with the engine in the back. I can definitely see why you went with a turbo. I'll try and get my hands on a good book or websites. I know turbo basics, but if I am to consider one in my aircraft, I want to know a heck of a lot more!! Thanks again John...

Jim

In some ways the turbo removes, rather than adds, complexity. After all these years we're still looking for a muffler that holds together. A few of the "prop on the front" guys may be getting close. Now find one that fits in a Cozy cowl. Intake and airflow are critical when NA and not as easy to control at the back. I think that the na Renesis may be ideal for a tractor, but perhaps not so for a pusher.

>will be "stealing" a lot of your ideas when the time comes.
Feel free. I found it very helpful to visit a few working installations in person. You take away a lot more from that than you do from pictures.

What did Ed say - I didn't see his reply to your original question?
John
