Hi Bernie,

Good point, Yes, you are correct the engine = mount is still=20 the same.

Besides, its really the increased ROC that = really tells=20 the story. I consistently get over 1500 fpm and even get up into = the 1700=20 fpm range on cold days lightly loaded. Previously it was in the = 1000-1200=20 fpm range.

Ok on the prop, Bernie.

I'm planning at this time to fly out to Bill = Eslick flyin=20 in Feb weather permitting - make a nice long flight for your = 9.

Hi Ed,

Don't forget to add that the P-factor is now in the opposite=20 direction and I believe you did not change angle of engine mount = to offset=20 this. I'm not questioning that you get more thrust with this set=20 up, just questioning if your criteria of lack of rudder = is a=20 good indicator.
