No spoilers or ailerons but...
The only time I was ever upside down in a helicopter was when one of the best pilots I ever knew did a past vertical wing over/chandelle type maneuver in an an old French Alouette III with me in the left seat. That's what I got for asking an ex Cobra pilot if he had ever been upside down in a helicopter. It's an old tech machine but a very nice smooth, responsive, powerful helicopter. And the in flight view through all that plexiglass is spectacular.
