I'm currently building this plane. I'm building version 3 with 2 - 52 inch swept wings. Plane is all wooded up. I didn't go with the big round cowl. I'm about to drill the 4 holes to mount the bottom wing. Outer struts will be 1/8th inch thick ply with balsa seats on each wing. Power is ST 60 ring. Outer struts are a pain. Keep in touch. Plane is very time consumming to build however I'm not in a hurry.
