I need to move my throttle axis over to another position. Did that, works fine - as long as I'm in a single engine plane. But how do I get both engines (in a twin) to respond to one axis? Initially (default) one lever did both engines. When I re-assign an axis, I can't seem to use that same axis again for the other engine without the system deleting the first engine assignment. How do I get both engines to respond to one axis?
