I thought the rotor RPM seemed very low when you touched down..unrealisticlaaly low even...apparently not. Seems the dev nailed it pretty well although the bleed off seems to happen at a slightly faster rate in this video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BkF4b6OuXJ0.html
Yeah they have nailed the physics of this beast. Those massive rotors carry a huge amount of inertia. Really need a dev to do a realistic 500 now so we have something that's lighter and less inertia for a challenge.
