Hello; I have built Goldberg, Sig, Great Planes, Ikon NW, and other kits, and would recommend Sig kits as the most "idiot proof" builds. I didn't have any real problems with any of them, but the Sig line seem to fly well, no matter how I managed to screw up, or how "funny" they look. Now I build without using the instructions, and still get great results. Now if I could only learn how to cover and make it look good.
