There is no twist grip, just big red switch to move from "idle" to "fly"
Flying the AS350 without twist grip, I know I would have to reach to the fuel lever and find some compromise switching my left hand between collective and fuel lever in case of regulator failure.
How does it works now in the 505? Is it because of the dual FADEC that there is no need for a throttle control? somebody else will have to help me understand how this works.
