Patent attributes
A multi-copter lift body aircraft has a push or pull propeller and a lift body that has a first airfoil shape on a front to rear cross-section and a second airfoil shape on a left to right cross-section. The lift body is made from a top shell and a bottom shell. The lift body has a nose and a tail. Multi-copter propellers are attached to the lift body. The multi-copter propellers provide a lift at low speeds and the lift body provides a lift at high speeds. Avionics can be stored in a hollow cavity of the lift body. The avionics may include a control circuit, batteries, and a radio receiver. The multi-copter has a lift body made from an upper shell and a lower shell. The lift body has an optimum attack angle at a cruising speed, and the lift body provides a combined lift mode.
