I tried adding a notch of null to the throttle axis but that made it worse, instead of getting 99% max and 1% fully back I got 2 % back and 97% full. It's realy strange cause I get 100% full and minimum 0% for the no. 1 mixture axis but thats the only one and if you check the sensitivies their all set exactically the same.
I went through all my other flight sims and tested them, CFS1, CFS2 .CFS3 ,IL2 ,IL2 Forgotton Battles+Aep , First Eagles1 and BOBII and they all produce 100, or in the case of IL2 and IL2 Forgotton Battles 110 % and 0 % min.
So it's only FS9 that doesn't produce full 100% power unless I hit F4 then you can see the throttle or prop go forword just a hair to make 100%, same fully back, in the case of twins the no2 mixture will still shut down the no 2 engine even though it just goes to 1 % min.
As I said only the no1 mixture goes to 100% max and 0% min and there is no difference in the way the sensitvites are set up, and only in FS9.In the case of 4 engine I just use the throttle on the CH Yoke to evenly controll all engines, (i don't bother with shutting down one engine to practice emergensys ,and for jets I do have to hold the brakes or hit f1 to shut down the engine other wise the plane will creep forword.
