Crazyed, I am sure that your cord will be fine. I would protect from heat as others have mentioned. That cord might have a finite lifetime though, no matter how well that you build it. That is the problem that I have had with nearly all of the numerous Estes rockets that I built with my kids. Once the cord is shot, then you have to make some modifications to incorporate a new cord and the rocket is already built. That is not always easy. You might consider installing a U-bolt on the top centering ring as an insurance policy. If something happens to your cord, you can always attach something via a quick link. You will really like your LOC-IV. The stock chute on my LOC-IV is too big. The rocket drifts a lot in the air when under chute. It also moves on the ground in a good wind. If you find that happens with yours, you can always change to a smaller chute. Good luck with the rest of your build.
