While this push propeller Yoshida model airplane kit is decidedly modern in design, surprisingly it dates from the early years of aviation history in Japan. The Crow design was the first rubber band-powered model plane to ever be built and flown in Japan. Designed and built in 1889, when its inventor was inspired while observing a crows wings in flight. The plane has a wingspan of 16 inches and overall length of 18 inches. The kit uses balsa wood, ultralight styrofoam and rubber bands. Complete illustrated instructions and glue are included. Suitable for kids aged 10 through 90.
