As with life there are mistakes there that I regret, but it's come together nicely and in fact I could build these in my sleep nowadays and probably do. Weighing in at sixteen pounds, which is very respectable given previous iterations, it's now ready to be rigged with motors and ESCs. It's upped in size to 50" square, primarily so the propellers can be pitched under-floor and away from harm.
I learned to fly in a Scottish Aviation Bulldog, and during running changes the canopy would be slid back as one cadet exited the aircraft via the wing and the other slid into place... all the while subject to the draught from an idling 200HP Lycoming engine and a constant-speed propeller. Which was enough to convince you of their lethality. And these electrical motors and props are just as convincing in that department, seeing them flight-tested at close quarters.
