For me this (final) effort to launch a credible personal air vehicle is a moonshot itself and so in order to give to the best chance of success in the longer term I retrieve the prototype in order to adapt it in three principal ways.
First, the 'Star Trek' model in the foreground has to go, if only to a museum. Carrying a third party for remuneration would require conventional flight certification, not overly cheaper in itself than an Apollo moonshot. Practically the market is for owner-drivers in the US, which has adapted its regulations to suit in the shape of the FAA's Part 103. In turn that means that a means of onboard control via sidesticks is the way forward.
Secondly if it is to be a pilot's machine it is going to need to be as manoeuvrable as a conventional helicopter, if not moreso. The only feasible way to do so in this case is to add a quadcopter at the base of the booth as well as around the dome, which pitches the centres of thrust and gravity around the mid-riff. This will give each of the drones the maximum purchase for flight-control motions.
Thirdly the adoption of that arrangement appearing at...
...so as to render the foot-print as compact as possible.
I order the parts accordingly, and principally in plastic.
