The Kayaba Ku-3 was a glider built in Japan in 1941 to investigate the possibilities of tailless aircraft. Building on the success of the Ku-2 design of the previous year, the Ku-3 was a substantially larger aircraft with several novel features. The small vertical fins of the Ku-2 were abandoned, leaving the Ku-3 with no vertical control surfaces. The crescent wing had three pairs of control surfaces on the trailing edge. The outer, less-swept wing sections had a greater dihedral than the inner sections.
