Les,

What everyone is describing is not a true snap by the definition of a snap (high speed stall with yaw). It is a maneuver that gets an upward break of the nose to please the judges and makes them believe the plane is stalled, and then spins the plane with aileron and rudder to make it wallow a bit.

In competition, it pleases the judges because is looks just like the real thing. It is easier to control and doesn't kill all your energy if you are on an up line. Believe it or not, the full scale unlimited guys came up with it first!
