 Anyone know of aerodynamic advantage(s) of the inverted-v tail on the
 Predators?

 I doubt it's aerodynamics..  It probably just keeps the prop from
 dragging on the ground.


 Matt-

 It complements aileron roll.  Upright V-tails fight it.  There's also no blanking at
 high alpha. (AoA)

 Good analysis Chris. Makes sense. I know you guys have thought a lot about it.

 Dump the Dems

Here's an updated photo for your files.  The FAA won't allow us test fly out of our
home airport, even though this we've test flown 3 other home builts at this airport.
 At this point we're waiting for the DAR inspection and trying to find a hangar at
another airport that isn't "locked in" by homes.

Cute Chris :)

Too bad it cannot have a rotary.
