Although technically this could be a scratch-build I posted this picture in the scale forum cuz more people might see it. It did come from plans and parts photos from an old Sig kit from the 60's designed I think by Bill Effinger. The original had a 72 inch span, but we scaled that up to 80 inches. The builder, John Anderson, made it a 4 channel with wing servos. It weighs in at 8 pounds, is covered with Monokote and powered with a .70 4-stroker.
