See, and to me that makes zero sense. A spinning prop doesn't magically increase in surface area to that of a disc. At any given time, the same amount of prop is confronting air. The only question is with how much resistance it hits the air. A spinning prop at least gives way.

Now, I know that full scale planes do feather dead engines, but from what I've read, there's a point at which the combination of mass/airspeed/surface area of prop create a tipping point, where it's better to windmill than to brake.

Not being a physicist, all I know is this: setting the brake on an ESC is one more step between me and flying, and after a day of trying with/without brake on multiple wings, I noticed absolutely no difference. That's why I say let 'er swing.
