RE: Torque roll??
Bill,
your stinger is in fact rolling due to torque, but this is not the 3D move commonly called a torque roll. A good torque roll is when an airplane, while hovering rolls left due to torque. Things you often see that detract from the move are left aileron input to make the airplane roll and the airplane climbing as its rolling. So when a guys pulls the nose up and feeds in left aileron to rolls as the airplane climbs slowly isn't doing a torque roll. A hovering airplane will usually roll "under its own steam" once the nose is pointed exactly straight up. A perfect 90, as they say.
