How long did it take you to even find that chafed spot, because I bet the actual fix was ten minutes and the hunting was the whole day right? That kind of gremlin is the worst because everything tests fine until it doesn't and you start doubting your own wiring skills. Six hours on one wire feels bad in the moment but honestly it builds character and you learn where the sneaky rub points hide on that airframe. Left wing root behind the fuel tank is a cruel spot too, tight space and you're probably bent in half the whole time. Bet you stood back and just stared at it for a minute when you finally saw the worn insulation. At least it was chafing and not some gremlin that comes back next week.

I used to roll my eyes at the paper wheel people in my design classes, figured it was just nostalgia and a way to feel fancy about being slow. Then I got stuck on a weird mustard palette last month and grabbed one from a thrift store for two bucks, mostly as a joke. Joke was on me, I had the whole thing sorted in five minutes and felt like an idiot for all the years I spent dragging sliders around. There is something about seeing the colors next to each other in real light that a screen just can't do. Keep the coffee ring, it's part of the tool now.
