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 HexaDeka is an eVTOL passenger concept design aircraft which has been specifically designed for advanced air mobility (AAM). The aircraft has one pilot and holds between eight to ten passengers. The aircraft has 16 propellers and 16 electric motors for aircraft propulsion. The aircraft has eight ducted propellers and each duct has two propellers. The propellers are configured in sets of four ducts located in the front of the aircraft and there are a set of four propellers located in the rear of the aircraft.

The windows of the aircraft are larger than conventional aircraft allowing excellent views for the passengers. The aircraft has a pair of horizontal stabilizers in the mid-front and mid-rear of the aircraft. The aircraft lands on retractable wheeled landing gear.


  • Aircraft type: eVTOL passenger concept design aircraft
  • Piloting: 1 pilot
  • Capacity: 8-10 passengers
  • Cruise speed: Unknown
  • Propellers: 16 propellers
  • Electric motors: 16 electric motors
  • Power source: Batteries
  • Fuselage: Carbon fiber composite
  • Windows: Windows larger than conventional aircraft for excellent views for the passengers
  • Landing gear: Retractable wheeled 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.
