Snap Roll
Lets see if I can get the party started.

Snap Roll is a stall type maneuver initiated by a upward or downward break in the attitude of the nose.
Initiated by up elevator and ailerons/rudder moving in the same direction= positive snap.
Initiated by down elevator and ailerons/rudder moving in opposite directions= negative snap.

What the plane actually does is the nose and tail rotate conically around a point somewhere near the cg of the airframe. If you drew a picture of it, it would look like two cones touching point to point with the 2 points at the center of the plane and the base of the cones ending at the nose and tail. Its not a barrel roll, the cg of the plane continues to travel down the same line throughout the maneuver but the nose and tail dont rotate on the line like an axial roll they rotate and revolve around the line of the airplane creating the cones. I think if conditions are right you can snap the plane without ailerons by pulling up hard on the elevator and inputting rudder to slow one wing down more than the other. If you give right rudder the rightwing slows down and stalls and the plane snaps over the right wing. Ive had it happen lots of times doing a flat turn with the rudder only and making attitude corrections with the elevator. Get into the elevator a LITTLE too much and all of the sudden the plane drops a wing and snap rolls into a spin. If you dont get wind over the surfaces ina BIG hurry the plane will spin all the way into the ground... That outta get some expert talking...
