Hi Ron,
I'm sorry, I duplicated this pic on the color scheme thread with along with this info. Should have made just one post.

Dad's Mach 1 was different in that he carved a pine plug for the fuselage to make ABS plastic fuse halves. He had access to the molding process by helping part-time at Delta Products (Grand Junction, Co) on some early ARF's. Unfortunately it came out very tail heavy (due to the plastic fuse), so with all the lead in the nose and Hobby Poxy paint, I think it ended up around 9lbs. Flew very fast and straight, but I think the wing loading on this particular one was higher than he liked. jeff
