Reverted here to a platform I developed independently and which we showcased at the GoFly Challenge in California in February of 2020.
What it does is to brace the outer airframe by incorporating a shear web in the form of the sandwich laminate which forms the core of the central flight-deck.
It works logically too, because each arm provides a pathway for the wiring to each pair of motors, which can be addressed in various ways to suit the operating environment.
I'll call it quits having started late in the day, but the focus of the full-scale self-build TELEDRONE that I'm designing here for a client in California is ~ literally ~ to be a 'day job'.
And that's in term of the time taken to construct, rather than a career path.
