Our trend so far is to the higher 2.85:1 ratio. The red line on the RX8 engine
is 9500 RPM. IMHO your money would be better spent on
testing and developing
the box for the three rotor and higher HP outputs.

Francois,
 I am very interested in both the engine and the separate gearbox. I agree with Paul that the higher ratio is a good idea. The use of 6000 RPM or higher is really fine for the rotary. I know that I am "preaching to the converted" here. The smoothness of the rotary is perfect for high RPM use. I could also use the 2.4:1 ratio. I really thank you for informing the newsletter and responding to the questions as you have. I won't be able to make Sun n Fun, but wish I could.
I hope you need a west-coast outlet! I would be the first to participate as well by offering to help do a FWF for the RV-10 if you are interested. I am just getting started with the 20B and could easily go with a different package. If this would be of use to you let me know offline.
I am rooting for your success!

With a variable pitch prop you can always slow the engine RPM and up the
pitch for efficient high speed cruise. The RX8 cruises at 80 MPH at 4000 
RPM as I recall.
