Today I spent some time working on the flight controls. I had previously order some 24 gauge music wire and today I installed it in the cable housing. The cable housing was made from bicycle cable housing used for brake cables. This is very similar to the housing called up but actually has a teflon liner to provide smooth movement. The music wire was ordered online from http://www.pianophile.com. I purchased a wire cutter for the music wire from my local Princess Auto store. The music wire had a curvature to it that was about 12 inches in diameter. This worried me a bit but after inserting it into the already installed housing there did not seem to be a problem.
