Width of the lower quadcopter's body has been depressing me, in turn a function of the fact that fibreglass mannequins are incapable of squeezing into smaller spaces, so that the accommodation needed to be much wider than it was long (15" by 10" even at half-scale)... as if I don't have enough to do with building an electrical aircraft.
This cost me half a day of staring at the ceiling wondering what to do about it ~ if not give up altogether ~ but God or providence supplied a solution in the form of an about face on the part of the mannequin. Turning it through ninety degrees meant the sides had to be raised by an inch or two, though you'll see it comes together in due course. Be fair to say there are periods when I never want to look a drone win the face again, but with a pandemic restricting practically all else it's that or self-immolation.
(It does also mean that the box is now much longer than it is wide, but this does at least allow for a reduction in the outline of the drone it sits upon, whilst providing the protection for the lower limb's that would inevitably have been raised as an issue at some stage along the way.)
