Ed,

Superception mods would be very interesting. My first reaction to the thought of an anhedral stab (aside from Jim saying "don't do it!" in his original article - he must have later...), was the tolerance for up elevator if keeping the rudder/elevator relationship per plans. With anhedral, the inner elevators would likely interfere with the rudder unless they were opened up in typical pattern fashion (cut at an angle).

Of course, a full height rudder would also be an option (again, despite Jim saying not a "good idea") along with the fuse faired fin LE. It seems to me that a simple built up "Tipo like" fin (3/32" or 1/8" angled sides) would be easier and cleaner than building up with heavy fillets on a slab fin but both are viable I suppose.

I guess the issue with anhedral stabs is cross-wind.

Great work!

David.
