If you look on the inside front cover page of SIC magazine I think it spells out the rights reserved aspect. I cant say that the plans show this or if so, consistently over the years. I didnt check very exhaustivley, just grabbed a few off the shelf. I think you could sell your magazine which includes the plans. I guess you could sell your plans removed from the magazine. Don't really think its right to copy the plans & sell them, legally or morally.
