With temperatures hovering around zero in the garage, it's no country for old men but nonetheless I remodel the 8' cat to exclude the side-panels to see if that makes much of a difference. Actually it doesn't, so long as two corners of each of picture-frame are braced with steel plates. These sub for tube-connectors that'll be used when I switch to tubular plastic or carbon-fibre sections.
There's a proverb to the effect that fools return to their folly, as a dog returns to its vomit. As if to prove its wisdom I've inset a photo of something I made in a hotel in Helsinki eight years ago while I still flew airliners. Laugh as you may ~ I am hysterically ~ you can see that the same DNA spreads across much of my work. Much like vomit.
Nonetheless eight years ago there was nowhere near the range of electrical equipment that there is nowadays, and drones were toys rather than a better way to do a variety of things... not least eliminating armoured vehicles.
In time, even dog-sick looks palatable.
