Complete the pair of frames to be used at head and foot of a vertical airframe designed to fly a pilot stood upright.
Been fifty years since the launch of Apollo 11 ~ which I recall watching on TV ~ and occurs to me how tasks do well to be split into component parts.
The space-frame installed between drones above and below an operator can similarly be treated as a module able to be built separately.
The quadcopters here have a base just twelve inches square, on cantilevers thirty inches long.
I've stuck with alloy and rivets because if it works on a 747 then it has to work here too.
