I've put HelioRC Spring flight controller into one of my main freestyle quads. I've installed the brand new "Odin" code. I'm running "buttered PIDs" whatever that is.
Basically, I've dunked my quad in Butterflight, fried it to a deep golden brown, and now I'm going to rip the shit out of it and see how it flies.
