Surigical tubing is generaly used for hi-start launching. I used (as I remember) 50 ft + 50 lb fishing line. But that was for 100 inch wing span. As I think about it The tubing might have been 100 ft. Anyway I have seen ad's in model mags that offer hi-start pkgs. You might google. You sure don't need as much for that size of glider. Vj
