A helicopter system has multiple rotors and methods of operation. The helicopter has a fuselage with four rotors and an engine operably connected to the four rotors for powered rotation of a rotor shaft with a set of rotor blades attached for each of the four rotors. Each of the rotor shafts is positioned in a housing with each housing attached at a lower end to a distal end of a beam with beams attached at a proximal end on the right side and on the left side adjacent to the nose end of the fuselage, and on the right side and on the left side adjacent to the tail end of the fuselage. All four rotor shafts are inclined from a lower end to an upper end toward the fuselage. All four rotor shafts may be inclined toward the nose end or the tail end of the fuselage.
