Hi Andrew.
Yes, indeed it is posable to fish wiring through the holes in the wing ribs.
Actually, should the occasion arise it is best to pull the new wire / tubing
through using the old wire you are replacing. I have replaced wiring in my old
Cherokee with that method.
My decision to add the tubes were for a number of reasons including ease of
repair to the internals. In addition I did not want any loose wiring flopping
around in the wing and next to the aileron bellcranks.
While I did not weigh the tubing or brackets I'm surprised with the estimate
of 4 pounds. Perhaps it could be that much. One thing is for sure. The tubing
will be heavier that grommets!
Happy building and HAPPY NEW YEAR!
