hi, group does anyone know of anyone documenting an RX8 conversion on the
web. : cliff

Sure Don Dunbar is installing an RX8 engine in his Mustang II. There may be
others.

Tracy Crook is already flying one.
Bulent

What else do you know about this Bulent?
I am surprised I havent heard anything from Tracy on this.
I guess he is pretty busy. Probably trying to fly off the 40 hours before
Sun & Fun. My guess is he is also using the 2.85 six pinion gear box.

I better bring the Everett Hatch Memorial Fund check book in case he
decides to enter the Sun 100 race and average more than 220 MPH.

I think he already started testing it:

"I'm just now starting on my Renesis evaluation.  First I wanted to compare
it to the earlier rotary (89 vintage) so I installed the RD-1C  2.85 : 1
drive and larger prop (intended for the Renesis).  Things are different
enough that it will take at least 20 hours to evaluate.  I'll be posting
detailed reports on the website.

On the second flight test of this configuration I had planned to do a
maximum performance takeoff to see how it compared.  I was fully aware that
the P-factor would be opposite (prop turns right instead of left) but I was
unprepared for the magnitude of it.  With full right rudder the plane was
still veering left.
 Things happened too quickly for me to be exactly sure of what happened next
but I think when the tail wheel lifted off, the plane turned sharply to the
left and I was certain that I was going to crash into the fence that borders
the runway.  No one was more surprised than I when the RV-4 lifted off and
cleared the fence (barely!).
 There were lots more interesting differences (most of them good) but it
will take several pages and more time than I have right now to explain them.
 My first recommendation when using the -C drive and a big prop is Feed in
power gradually on takeoff until rudder is fully effective.  A bit of right
offset in the engine mount might also be in order (mine has none).
 Tracy"

It is starting to act like a P51 or a Gee Bee :) I am really excited about 
what is going to happen when we stuff 450 HP turbo 13B rotary in an RV3 or RV4???

Maybe we have to bump up the minimum race average to 250 MPH :) 

Just kidding. Not this year.
