A self-propelled flying toy includes a body defined as having a front section, a center section and a back section each along a longitudinal axis. A ducted fan is located within the body substantially centered about the longitudinal axis. A motor is mechanically coupled to the ducted fan and a power source is coupled to the motor. An air-inlet is located substantially within the front section in airflow communication with the ducted fan. An air-outlet is located substantially within the back section in airflow communication with the ducted fan. At least two angled surfaces are fixed relative to the body and located substantially within the front section. Each of the at least two angled surfaces are evenly centered about the longitudinal axis and facing an opposite thrust-generating rotational direction relative to the ducted fan.
