A couple of Kaotic images:

Photo 1: The Ino-Lab 250 is a fabulous digital servo for $20, but it's so tiny I had to make a stepstool tray to line up the pushrods. Same pic also shows the remains of my failed attempt at a trailing-edge exit air duct. Clean-up time...

Photo 2: Realized too late that the battery hatch could easily have been made flush. Next time. But AK Models does great laser cutting for cheap.
