I like the idea of being able to control throttle a little if approaching with a tail rotor failure / loss of control etc.
It's true you can't do 'throttle steering' with it, but at least it's a big switch right under your thumb so unlike an AS350 you don't have to take your hand off the collective to activate it. I reckon you could probably get a semblance of 'between' throttle by blipping it, but I don't know if Bell have played around with that idea yet.
