A rotorcraft (100) capable of a hover mode (191) and a forward cruise mode (194) including a fuselage (102), a first electric propulsion system (130), a second electric propulsion system (160), and an electric power control unit (170) to control power to the first and second electric propulsion systems (130, 160) in the hover and forward cruise modes (191, 194). The first electric propulsion system (130) is a tip jet cold flow system that imparts rotation on a pair of rotor blades (154) disposed above a top surface of the fuselage (102), and a first electric motor (132) configured to drive the tip jet cold flow system. The second electric propulsion system (160) includes a propeller (164) disposed in the rear of the fuselage (102) and a second electric motor configured to drive the propeller (162).
