Hi! Ed
I guess I missed something, how can the P-factor be in the"opposite"= direction after shortening the prop 2"?

 Hi Bernie,
 
Good point, Yes, you are correct the engine mount= is still the same.  However, since it only causes 1/2 ball deflecti= on in cruise, I not certain that the mount is that far offset in the wron= g direction.  Guess I should add a few washers and find out - just k= idding.  One of my numerous projects is to fabricate some new engine= mounting brackets (keeping the same mounting frame) with the offset to t= he opposite side. 
 
Besides, its really the increased ROC that really= tells the story.  I consistently get over 1500 fpm and even get up = into the 1700 fpm range on cold days lightly loaded.  Previously it = was in the 1000-1200 fpm range.
 
Ok on the prop, Bernie.

Hi Ed,
 
Don't forget to add that the P-factor is now in the opposite directi= on and I believe you did not change angle of engine mount to offset this.= I'm not questioning that you get more thrust with this set up, just= questioning if your criteria of lack of rudder is a good indicator.=
 
Took your prop and the sensenich to plant city and left both with th= em. Will probably be able to pick them up on the way home from Memphis af= ter Christmas.
 
Cheers and Merry Christmas in NC,
Bernie
