I bought a roll of thick 3/4" PVC non metallic conduit. This is flexible and will bend and fit anywhere. I used sharkbite suspension clamps riveted in place on each of the 15 wing ribs. These are plastic and will not corrode. They hold the conduit in place very well. Before I rivet bottom skins I will apply some tank sealant around the clamps to help with any vibrations.
I beleive this will be perfect for running my ZipTip wing wiring and pitot, etc. I was thinking of adding another run of couduit from the center rto the root rib but I will add later only if needed.
