#1: Location. I see from previous discussions that at least one person has mounted the pitot tube in the most outboard wing bay (vs the more common ~mid-span location). I'm very interested in using this location; it seems to provide some solid benefits vs the mid-span location. Specifically, maintenance access is simple (accessed with the wingtip off), and there's no concern whatsoever of interference with the aileron control system (not that I'd consider this a major concern).
The setup I'm considering is to have the pitot mount on the inboard side of that outboard bay. The hard lines from the tube would bend to outboard, and be secured to a piece of angle that would bridge the lightening hole. This would provide really easy access to the pitot/AoA line and electrical connections.
The main thing I'd need to figure out is how to brace the mount against the rib - the little piece of angle provided by Dynon with their mount doesn't work on the flange side of the rib.

#2 involves routing of the pitot/AoA lines. Rather than drilling dedicated holes through the ribs for these lines, I've been intending to run those lines through the conduit with the wiring. "Conduit" in this case will be 3/4" PEX tubing, so there will be plenty of room in there. I guess the one issue I can think of is that if there was a short in those wires that got things really hot, it'd have a greater chance of destroying my airspeed reference than if the lines were routed elsewhere.
Any thoughts on either of these ideas? I spent an inordinate amount of time today just staring at the mount clamped to the spar web and using my imagination...
