A multi-copter lift body aircraft has a push or pull propeller (26) and a lift body (70) that has a first airfoil shape (71) on a front to rear cross-section and a second airfoil shape (72) on a left to right cross-section. The lift body (70) is made from a top shell and a bottom shell. The lift body (70) has a nose (22) and a tail (25). Multi-copter propellers (60) are attached to the lift body. The multi-copter propellers (60) provide a lift at low speeds and the lift body (70) provides a lift at high speeds. Avionics (68) can be stored in a hollow cavity of the lift body. The avionics (68) may include a control circuit (65), batteries (66), and a radio receiver. The multi-copter has a lift body (70) made from an upper shell (36, 38) and a lower shell (37, 39). The lift body (70) has an optimum attack angle (91) at a cruising speed, and the lift body provides a combined lift mode.
