Since 2007, Thibault Chatillon has been working with, inventing, flying and designing drones, including designing passenger electric vertical takeoff and landing (eVTOL) aircraft. Chatillon is based in Lyon, Auvergne-Rhone-Alpes, France. In addition, he's designed the first vertiport network in France for eVTOL aircraft and drones. Chatillon is also working on innovative eVTOL aircraft design concepts for advanced aerial mobility (AAM) and air racing. On several of Chatillon's social media accounts, his handle is Tibo Cat Lion.

The NautiQuad is a one passenger multicopter eVTOL hoverbike concept design that can land on the ground or on water. The pilot sits in an open cockpit on a motorcycle-styled seat. The aircraft has four ducted and guarded propellers, each placed on the corners of the aircraft. While this hoverbike has a multicopter makeup, there is a unique design feature where the rear two propellers will rotate to a vertical position to provide more propulsion when in forward flight.

The inventor foresees this aircraft to be used as for advanced aerial mobility within a city, in rural areas, on a coastline, on lakes and on islands. The aircraft will be very useful for rural and hard to reach areas, where there are little roads or where roads take too long to travel short, medium and long distances.


  • Aircraft type: eVTOL personal concept design hoverbike
  • Piloting: 1 pilot:
  • Propellers: 4 ducted propellers with propeller guards on the top and bottom of each duct
  • Electric motors: 4 electric motors
  • Power source: Batteries
  • Fuselage: Carbon fiber composite
  • Window: Open cockpit
  • Landing gear: Lands on its fuselage on the ground or in water
  • Safety features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers (or ducted fans) and motors on the aircraft so if one or more propellers (ducted fans) or motors fail, the other working propellers (or ducted fans) and motors can safely land the aircraft. There are also redundancies in the sub-systems of the aircraft. Due to its ability to land in water, this makes the aircraft much safer than aircraft that can't land in water.
