Vance, Rich and Bill, Since Tracy's gear box turns the prop the opposite

guys think of putting in 1-1/2 degree thrust line off set in... also the

opposite way.

I think Tracy ignored the thrust line offset angle. Tracy did you off set

your thrust line?

If not do you notice any strange flight behavior?

I have no offset and the only thing I notice is that I have to push left
rudder instead of the usual right for most planes.  My trim tab is about the
same size as offset Lycoming powered RV's but on the opposit side.  I sized
it for my normal cruise (172 mph) at a lower power setting than the book
value of 192 (75%) so the offset to the left may be desireable if you run at
WOT.

BTW, finally got around to doing some performance measurements with the new
engine & muffler combination.  I was totally jazzed to find that at 14,000
feet I could cruise at 202 mph burning 8.25 GPH (WOT).  Not bad for a
relatively dirty RV-4.

OK how about getting ready for the Sun 100 race this year?
$500 out of the Everett Hatch Memorial fund donated by newsletter subscribers 
to the first rotary powered airplane to exceed 200 MPH in a U.S. cross country race. 
You deserve that money Tracy :-) It is just sitting there in the bank earning
interest.
