Our focus is on building the smallest, fastest and safest personal VTOL aircraft in the world. With the current level of battery energy density (220-250 W·h/kg) it is simply impossible to achieve our design parameters with electric propulsion. This will definitely change over time but we don't expect it to be the case before 2030. When energy density does improve (and is reliable, affordable AND safe) then we will be ready to adapt our air-frames for Electric Ducted Fans (EDFs). The great thing is all our stabilization, flight and autopilot systems will transfer over!
