Fred Moreno's suggestion to use the plastic conduit in your wings makes
sense if you consider that it's non-conductive - so even if long-term
vibration rubs a hole in the wire insulation, not much is going to happen.
Of course, if the aluminum tube isn't grounded anywhere, that holds true for
it also.

An interesting thought, however, I'll bet that at the low temperatures
mentioned in Fred's post (-40F, I think it was) the plastic tubing will be
as stiff as the proverbial wooden ----. Maybe using plastic doesn't buy you
all that much after all - at least when encountering such low temps. Anybody
know?
