I've been researching and planning the routing of Pitot/AoA lines and many builders of -7/8's have run the lines through the main ribs close to the spar web. There's quite a difference in the aileron bellcrank and the -7/8 lack the reinforcing angles of the -4. My main question is whether running the lines aft of main spar creates some challenges in routing into the fuselage that doesn't exist with the 7/8 aircraft builders. I have a pre-view plan set for an -8 and the center section certainly doesn't have extra holes for running lines that I can see. I assume in either case you'd have to run lines above the main spar in the fuselage sidewall to get to the instrument panel.
I have already installed the SafeAir1 pitot mast just outboard of the stock location and plan to use the Dynon unheated Pitot/AoA. After careful consideration taking into account Van's recommended wire routing (here: http://www.vansaircraft.com/pdf/Wing_Wiring.pdf) I think the following layout works best. The Pitot/AoA lines would be routed at the top of the rib through snap bushing and the wiring would be routed at the bottom in the Van's corrugated conduit via a 3/4" hole. Looking for community feedback before making this permanent.
