Default RE: Anhedral Stab effect??

Actually, the effect is pretty minimal. If doing it for appearance, no problem.

The anhedral adds a bit of vertical-fin stability, but it does change the stab pitching moment a bit, and it creates more tail side-area.

For sport flying, you will not notice a huge difference. For some aerobatics, knife edge, stall turns - yeah, it is noticable, especially in a cross-wind.

Image here is what had envisioned for the Patriot XL - if I get a spare week to build it.
