Autorotate a R22
A few years ago I was given a quick demo by a chap who,was quite determined to show me what a hotshot flier he was (R22 machine). The demo included quick stops at approx 50ft. He carried out a number of them. I now know what a complete pratt he was. Dare I venture to suggest that there are many conditions even when observing the height velocity chart that low inertia 22 blades could get the unwary into an irretreivable situation. 1.1 seconds is not enough! If the brakes on your car had a 1.1 second delay but only during emergency stops, would you put up with it. Write to FR and tell him you want more inertia. He only needs to completely re- design the machine but starting with the blades and working backwards this time. The blades weigh about 30lb but the centre of mass is only about 4 feet from the root
