Animation issue in FSDS 3.5

I know I'm a bit late to the party, but I would like help in getting the throttle levers to act independent of each other. I have seen other posts, but the links to the answers all seem to be gone now. Any help with this issue would be greatly appreciated.
That helps with some of it. I fixed the issue with throttles by creating 3 other animations named Lthrot, Lengine, Rengine. it seems FSDS3.5 is very strict on what names it will accept for animations, as Engine1 didnt work. Now I hace to figure it out for the mixture levers next.
