10.0pt;mso-bidi-font-size:12.0pt;font-family:Arial'>Thanks Matt, as with any
other design change it needs to be tried to understand the effect. I always
felt that the bottom running stab in knife-edge or the outer stab when the
fuselage is yawed is more effective than the other side and dominate. In the
old days I was able to balance knife-edge pitch by adjusting one elevator up
and the other down. When an annhedral stab is yawed it becomes unbalanced
resulting in a pitch force change towards the top of the fuselage. If this were
true it should also produce a slight roll with yaw. I will probably never
understand as much about pattern plane design as I would like, I just try
things. It either gets better or it gets worse and this is only one of many
design considerations.<o:p></o:p></span></font></span></p>

prefer to call them a viable option for pattern models and here're my
thoughts on the subject. First off, fundamentally, they don't change how the
wing is stabilized in pitch compared to a flat stab...same physics apply.
Anhedral area however is the resultant of two component areas, horizontal
which dominates and a vertical which adds to the already eixsting vertical
stabilizer area. It may be thought as area added to the ventral side of the
fuse without adding a subfin. This often helps settle some unwanted thrust
vector forces namely the much cussed and discussed dredded pitch to belly with
top rudder. Does it always work as prescribed? Does anything in our sport ever
always work as prescribed?</span></font><font color=black><span

color=black face="Times New Roman"><span style='font-size:12.0pt;color:black'>Rolling
circles may be helped with anhedral in the stab. When the anhedral angle is
"just right", there is no region during rotation (X degrees from
horizontal) that completely blanks out the stab as can happen with flat stabs.
Does is do wonders? I don't think so but it certainly does not hurt.</span></font><font
