Hi, Jim! First off, remember its a fiberglass plane. I ran one bar down
each side of the fuselage and put one layer of fiberglass over each.
Another way would be to put in one bar, fiberglass over it, put the
second conductor over top of the first, then fiberglass over that. That
construction yields a good-quality distributed-capacitance for
transient suppression, and the two close-together conductors give good
EMI cancellation. Paul
