                                          Enlarged below is the inscription which appears between the cockpits of this autogiro.  The
                                          YG-1 series (1 YG-1; 1 YG-1A [above] and 7 YG-1Bs) was developed from the civil KD-1
                                          This autogiro, first certified in 1937 differed from earlier designs in that it had been devoid of
                                          all wing, aileron, elevator and rudder control surfaces.   All directional control was achieved
                                          in the tilting of the rotor head.   The main rotor had a span of 40 ft.
