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 Haut QuadrAxes is a one passenger eVTOL personal flying device concept design. The aircraft has a simplified design reducing complexity, reducing weight, and increasing safety and reliability. There are four ducted propellers positioned above the pilot and are held by a strut that is attached to the rear of the seat. The pilot is seated in an open cockpit on a seat and the pilot's feet are on foot rests attached to the landing gear. The landing gear is a fixed tricycle strut-type landing gear

The aircraft can be used for intercity or rural travel, for personal use, sporting use, vacation use and air tourism.


  • Aircraft type: Multicopter eVTOL concept design hoverbike
  • Piloting: 1 pilot
  • Propellers: 4  ducted propellers, the ducted propeller are over the pilot
  • Electric motors: 4 electric motors
  • Power source: Batteries
  • Fuselage: Aluminum airframe
  • Cockpit: Open cockpit with a single seat
  • Landing gear: Fixed tricycle strut type landing gear
  • 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.
