How do they do it?

    How can some airplanes sustain their flight level even when they are upside down?

    Poorly. :)

    But it can be done. They are not really in level flight, they angle the plane high (or low?) so that the wing - even inverted - provides lift due to a high angle of attack. The engine is also pulling upward.

    Along the same lines, the fuselage may appear to be horizontal, but the wing still has an angle of attack greater than 0.

    Stunt planes often have symmetrical wing sections. In this case, the wing itself will perform just as well upside down.
