Proud of this as it encapsulates the best of my thinking over recent months. It's ready to be transferred to another team-member who will attempt to get it flying independently with a smaller of batteries.
Whilst that's happening I shall continue construction of a 'phone-booth' of 50cm square and 150 tall, large enough to include a seated passenger whose lower legs will nonetheless dangle outside.
Beneath the seat a larger set of batteries will transfer the current up the four columns to the motors that you see above, via an avionics bay contained within a 'dome' that surmounts the centre-section.
The net result will look much like the classic K8 telephone-kiosk (as seen at http://www.the-telephone-box.co.uk/kiosks/k8/) but equipped with eight propellers and able to 'teleport' people who might otherwise have telephoned instead.
