We have this local hobby shop about 2 miles from where I live and on the cieling above the entrance is a 12' x 12' AA 744, and there are pictures of it when it actually flew. Near the back of the store there was a 6' x 6' Delta DC-10.
Sometimes Model Airplane News magazine will have something about airliners in them. Back in 1991/2 I saw that someguy made both a model of an XB-70 and a Concorde -- both were like 12 feet long!
Me, I don't R/C, but I'd love to. I draw planes and to see how my ideas favor in the real world without going to NASA's wind tunnels would be a blast.
The meaning of life is curiosity; we were put on this planet to explore opportunities.
