To Bill Jepson: Yes, we shall most probably sell our planetary

reductor

drive separately to private rotary engine owners.  We'll be

taking

orders for both the whole engines and for the drive soon,

hopefully

already at Sun'n Fun.

Francois,
 Fantastic news. The more successful flying rotarys the better! I

really wish you well, as a mechanical engineer

I really like your purpose built Planetary. The slow speed isn't a

problem for me I'm building an RV-10 and would prefer to swing a

large

prop. The ability to use a standard constant speed prop is one the

things

that has me hanging back on Tracy's unit. Tracys design is fine, but

the

RV-10 will

need a C/S and I don't want to spend as much as my plane
on a electric! I'm running a 20B by the way but normally aspirated

and

limited to 260 hp the max allowed for the RV. What is your reduction
ratio Francois? We rotor heads want your certification efforts to

succeed

since it will bring acceptance to rotary power. Do you have any

rough

pricing for the engines yet? Non certified would be fine for the

homebuilder.

Many Thanks for your Efforts!,
Bill Jepson

Thanks for your good wishes, Bill.  We need them, the road ahead of us
is still long and rocky!

The RV-10 is probably a perfect fit for our redactor drive as it allows
a larger diameter prop... so, no issue of having a special prop done to
take our slower prop RPM or sacrificing t/o performance.  Our present
reduction ratio is 2.8231:1 but we are seriously considering changing it
to 2.4-2.5:1 in our first commercial units.  The issue is open, awaiting
some feedback from flight testing.

As to your question on price, please refer to the "general" and
"official" announcement I plan to give to all the subscribers to this
news letter.  I would love to but I just don't have the time to respond
to everyone in person on "general interest" questions.

Best regards,

Francois Badoux

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.
