One embodiment is an aircraft operable in a hover mode and a cruise mode and including a fuselage; wings connected on opposite sides of the fuselage; a canard connected to the fuselage forward of the wings; forward propulsion systems connected to a trailing edge of the canard on opposite sides of the fuselage; aft propulsion systems connected to trailing edges of the wings; and wing-mounted propulsion systems connected to leading edges of the wings. The aft propulsion systems are tiltable between a first position when the aircraft is in the hover mode and a second position when the aircraft is in the cruise mode. Each of the propulsion systems includes a rotor assembly comprising a plurality of rotor blades. The propulsion systems are substantially equidistant from a center of gravity (CG) of the aircraft.
