Well, I couldn't put this off any longer. Today I ran the primary power cable along the left side of the fuselage. In addition, I ran two 3/4" plastic corregated conduits also along the left side. Tomorrow, if all goes well, I'll run an additional three 3/4" conduits along the right side. I suspect this may bet overkill, with a total of nine conduits, but they weigh next to nothing and retrofitting would be a nightmare.
