So it's not a snap roll. Thanks. I guess I probably haven't even seen or recognized a real 'snap roll'.

And by the way I don't 'slam the sticks to the extreme'. I fly pretty well, especially for a beginner, just made the mistake of ruddering one way, then the other, while a little under powered. It's what I call learning. Generally I can give rudder and counter it with ailerons and a little elevator, but rudder right then left produces some pretty serious nose-down rolls, and didn't have enough power for the elevator and ailerons to do much only 10 feet from the ground.
