The above two posters are bang on the money. Overspeeding anything is bad. The coyote used his judgement and didn't need to overspeed the light rotor systems on two engine failures, he is to be commended. Can you give us anymore details coyote? How heavy, at what height and onto what surface.
My original post was simply saying that once the aircraft lets you down and a less than pleasant landing is likely, don't dismiss your judgement to keep a bunch of anonymous internet posters happy.
