Hi Doug, I put in an 1/4"
offset (front of the stab right for my 2.17:1 RD1-B drive). My
engine mount is also offset 1.25 deg and I find that I still use a lot of rudder
on take off and climb. I also need 3-4 pounds of rudder in fast cruise to
keep the ball centered. Slow cruise (110 kts) I need no rudder.
I will probably install a small trim tab.
So I would probably
recommend at least the 3/8" offset since I believe the conversion consepts mount
is straight.
If you are going to use
the RD-1C drive. Besides offsetting the other way, the big prop you will
be using puts the tips further out and increases that p-factor even
more.

I am mounting the vertical stabilizer and I'm now to the point where I
drill the forward attach point. I therefore was wondering if I should
center it along the fuselage center line or go with Van's recommended
setting? I am using a conversion concepts mount.
Thanks for your input.
