I am also currently using a 2 stick game controller and had wondered the same thing. Thought about a simple rubber band to keep the throttle at idle unless held. But that would get old too after a while. In general, I much prefer using one of my radios with an interface cord, but I found that lots of simulator time= broken return springs on jr421 radio pots ( not gonna risk my old 783 any more). I think it would be cool to modify the game controllers to add stick length also, because they seem much less forgiving than radio/interface cord. Better than nuttin tho.
