It's actually not that different, since the disc of thrust's direction in a helicopter is bound to the helicopter's orientation itself. Thus, there's no stabilizing momentum intrinsic to the system. The pilot needs to constantly balance it manually (if there's no computer help of course), which makes a helicopter so hard to operate.
