It's not a thing, however acrobatic aircraft often have symmetrical airfoils, such that they can fly inverted.

Make that, such that inverted flight has the same stall margins as normal flight.

Right, even a Cub with its flat-bottomed USA-35B will fly inverted, but in terms of angle-of-attack you would have no room for error, and the gravity-fed fuel system is going to cause you some problems too.
