Rick,
I think others have already answered this well, but here’s two = more cents: The Lancair-defined locations for throttle, mixture and prop controls = worked out very well for me. I don’t have a blueprint/layout for these, = but could make you one from my airplane if you advise me soon—engine = going on (again) in a few days; very difficult to get a good pattern after that! = =A0Focus on the cable run in the engine compartment, rather than behind the panel (spaghetti behind the panel as you have to; minimized in the engine = compartment as you can) Several reasons for this, but main one is to keep them = working freely for as long as possible…and they are difficult enough to run in a straight line inside the engine compartment…just wait; you have a = real treat in store to install these! BTW, if you haven’t planned/used isolation sub panels to mount your cables to the instrument panel, this = is almost a standard practice today, and is the only way to get the panel = out without disconnecting and pulling the throttle/other cables back through = the firewall… Most folks use one for the throttle/prop/mixture, and a = second for “all others.” I used a third one on the left side of the = panel for the parking brake.

The smaller heater control and similar cables are more = flexible and easier to work with, but the same general concepts apply—snake = them behind the panel and minimize this in the engine compartment as you = can.

Any other thoughts/insights/lessons = learned???
