I'm new to this site and will be building a Sig 1/2A Skyray that I just ordered very soon, to relive my childhood and hopefully teach my 7 year old son to fly as well? Anyway, I've come across a few posts here and there about people using "Spiderwire" brand spectra fishing line for control lines, since the claim is that it is better and less stretchy than the dacron that comes with the Sig 1/2A handle. So I'm just wondering what type of "Spiderwire" people are using as in the test strength, 10 lb, 20 lb, 50 lb? I'm planning on building with electric power since I've been flying parkflyer RC and have some gear which should work, but I am interested in going with the lightest control lines that will safely fly 1/2A size control line planes, so any help would be greatly appreciated and especially website links so that I know exactly what to look for, thanks in advance for any and all assistance with this.
