Scale RC aircraft..wings
Even though were talking about full size aircraft, many commercial jets, fighters, and recip aircraft are built in the smaller RC form to exacting reproductions. Granted the weight to power ratio is more, but we have the luxury of flying many types of airfoils in all realms of flight.
Wings with High Dyhedral (sp?) or Swept wings dont like to fly inverted very long, without large amounts of up elevator (while inverted)...they tend to right themselves naturally, Swept wings tend to do nasty things weh inverted, like tip stalls where the aircraft will enter an inverted barrel roll and nose over steeply...
Semitrical wings will fly either way just fine, they dont care which way is up or down, again if they are swept though they will tend to tip stall as the washout no longer supports lift in the correct downward direction....
On the other hand, but enough horsepower behind a brick and it will fly as well...just my experiences with the RC world of flying. I know there are other differences from full scale aircraft, but the wings are surprisingly similar.
