Interesting thought !  Guess there is enough polyhedral ?

Brings up another important topic, how important is the tail fin ?  Even on many RC "flying wings", there is a vertical piece at the tip of each wing, but then planes like the B-2 stealth bomber has no vertical surface Head Scratching

I read somewhere that the B2 uses computer controlled air brakes at the edge of the wings for keeping it lined in the wind. But then how do eagles cut through high winds without any vertical surface.

The tail fin is needed when you have a fuselage.

Wondering if there aren't any models with a fuse without the tail fin ?  Some of the dual wing ones (one wing up front, and one at the back) ?

There is one UAV called ScanEagle, it has two vertical stabs but doesn't have a horizontal stab. Over all a very beautiful plane.
