Yeah I would love to base a home cockpit off of the TBM-900 but without an axis or dedicated switches for the various mixture/prop/throttle settings its practically impossible to implement the throttle controls.
Really wish they would implement individual switches for each possible position instead of the mixture_up_a_bit/ down a bit routine. That cant work with a physical throttle, unless you have the design skills of a NASA engineer. It would require quit a complicated aparaticus to work right.
