[NSRCA-discussion] Annhedral Stab

[Nat Penton]

Jim
I used anhedral, about 5 degrees, on my Express because the wing/stab 
separation is effectively zero. My fear was interference from the wing shear 
line and the idea was to have the stab operate in a broader range of the 
wash.

It is impossible to get the stab out of the downwash.

I have experienced heart pounding rudder interference from forward fins and 
wanted to avoid those puzzling instances of "was that me or was that the 
airplane".
