The invention relates to a vertical take-off aircraft (1) which is designed as a tail-sitter and, after the take-off, transitions in full from the substantially vertical hover attitude into the horizontal attitude, comprising: an aircraft fuselage (2); a rigid wing (5), fixedly connected to the aircraft fuselage (2); and at least one motor-driven propeller (11), which is arranged so as to be fixed in position and has propeller blades (12); and a motor-driven rotor (16), which is arranged so as to be fixed in position and has rotor blades (17); wherein the propeller (11) is driven at least in horizontal flight by a first drive shaft (13) and the rotor (16) is driven in hovering flight, but not after the transition into the regular horizontal flight, by a second driveshaft (18); wherein the first and the second driveshafts (13, 18) extend coaxially with one another; and wherein the rotor blades (17) are designed so they can be folded in with respect to the aircraft fuselage (2) in horizontal flight of the aircraft (2), while the propeller blades (12) are not designed so they can be folded in with respect to the aircraft fuselage (2). The invention also relates to a method for operating a vertical take-off aircraft (1).
