Beats me why it would bother him. I have been doing it that way for as long as I can remember and I'm an old coot (:-).

I'm assuming here that you mean a small plastic tube and that it is separated from the other wiring as much as possible. I usually mount the tube along the top inside edge of the fuselage and exit the tail. However on my Senior Telemaster I surfaced just behind the trailing edge and attached it to the fin. I won't do it again though because I seem to catch it on too many things while in the vehicle or pit area.
