Rotor brake required!!!!
Park with the wind dead on the nose, works up to 50 knots or so. That's the easiest way to keep the disk under control. Don't get excited about keeping the back clear- pushing the tip down in front eventually means the blades start bouncing, and things get random after that (bad).
Personal preference is against a teetering head, they get interesting as the NR drops. Really, really hate(!) the Longrangers, with the vertical fins on the horizontal stabs.
