Robert Kovacs is an industrial, automotive and aeronautical designer based in Hungary. He is a prolific designer making futuristic concept consumer products, automobiles, motorcycles and electric vertical takeoff and landing (eVTOL) aircraft. His online portfolio features the eVTOL multicopter prototype, LIFT.

Racer II is a futuristic concept design Urban Air Mobility (UAM) motorcycle-styled hybrid-electric vertical takeoff and landing (VTOL) one passenger aircraft. As this is a multicopter aircraft, and based on the design, it has been designed for high speed travel. When battery technology has the ability to have an extremely high energy density and if this concept aircraft, if ever made into a production model, would most likely be changed over to an eVTOL aircraft due to the cost of electric is twice as less as fuel. If the cost of gasoline per year is $2,000.00 USD for your vehicle, when you switch to an all-electric vehicle, the cost is approximately half the cost, or about $1,000.00 USD. Saving half the cost of energy to fly an aircraft would be worth the cost of converting any hybrid-electric VTOL aircraft into an eVTOL aircraft. 

The aircraft has a small windscreen with the pilot sitting in an open cockpit, and to control the direction of the aircraft, it has motorcycle-styled handle bars. The aircraft has four ducted fans and are quite large which would be needed to develop the thrust for high performance racing aircraft or if used as an around town UAM aircraft. This aircraft has an open fuselage in the rear revealing what is most likely a gasoline powered engine to create electricity for the electric ducted fans. 

It also looks like there is one vertical stabilizers for yaw control and has a tail dragger type device which could possibly have three purposes: 1) As another vertical stabilizer, 2) As a safety feature, so if the aircraft bottoms out in the rear, the aircraft could take the hit without damaging the fuselage and loss of flight control, and 3) It could be used as one of the tricycle landing legs for the aircraft. There is also what looks like forward flaps or possibly ailerons in front of the rear ducted fans, apparently placed for stability during tight curves or making fast adjustments during flight. 

Kovacs has not provided an estimated cruising speed or flight range for the Racer II hybrid-electric VTOL aircraft. Neither has he provided any information on how the aircraft lands. From looking at the drawing, it looks like Racer II had retractable landing legs. Installing retractable legs would provide a more aerodynamic body during flight, would keep weight down to a minimum and the pilot could easily land the aircraft where they wanted due to its ability to takeoff and land vertically. 

If this aircraft came into production and was aerodynamically sound, it would probably be a favorite for young racing enthusiasts and for those who want to travel in any urban environment in a sporty VTOL aircraft.

Specifications:

  • Aircraft type: Hybrid-electric VTOL aircraft and a possible future eVTOL aircraft 
  • Piloting: 1 pilot 
  • Capacity: Approximately 113 kg (250 lbs)
  • Cockpit: Open cockpit
  • Cruising speed: Unknown
  • Range: Unknown
  • Ducted fans: 4
  • Electric Motors: 4
  • Landing gear: Unknown; however, most likely retractable landing legs 
  • Safety Features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers and motors on the aircraft so if one or more motors or propellers fail, the other working motors and propellers can safely land the aircraft.
