inverted flight is not just flipping a switch, it's the controls, 3 of the 4 controls are reversed and you have to cope with that while and after you've flipped it over. i'm doing inverted 'hover' right now (kinda like those first upright ones except you can't cut the throttle) adn man... it takes alot of work. but... i don't have a sim... and i'd say is not like, upright you don't flip the switch, and inverted you flip it... it just changes pitch/throttle curves so that THE HELI is capable of hovering inverted.
