Abstract: Flying apparatus is provided including a housing with two or more rotor means associated therewith. The rotor means are arranged to rotate about substantially parallel axes in use. One or more vanes are provided with said apparatus to help stabilize the apparatus in use.

Abstract: Flying apparatus includes a housing and rotary means associated with said housing capable of rotation in use. The rotary means includes two or more rotary blades. Each rotary blade has weighted means associated with at least a part of a leading edge thereof.

Abstract: Flying toy apparatus is provided including a housing with drive means provided therein for driving rotation of rotary means associated with said housing. Vane means are associated with said housing and said vane means rotate in a counter direction to the rotation of said rotary means in use. The vane means are arranged substantially vertically in use.

Abstract: A model helicopter creates lift using rotor propellers mounted to the rotor arms of a gyroscopic rotor assembly. A controller converts front-back, and left-right inputs into speed control signals used to vary the speeds of the rotor propellers at selected positions of the rotor assembly as it rotates. The varying speed of the rotor propellers at selected rotor positions produces thrust vectors at those positions. The resultant thrust vector determines the direction of the helicopter's flight and enables it to pitch and roll in response to the front-back and left-right inputs. The rotor assembly can have two or more rotor arms, each with a propeller. The helicopter provides left-right yaw control with a yaw propeller on the helicopter body. Electric motors, or motors using other conventional power and speed control methods, can be used to drive the rotor and yaw propellers.
