just an idea... if you can't accept or understand the numerous replies, what about actually attending the Robinson Factory Course? No offence to anyone else that's been replying to the endless challenge to provide the answer you want to hear, but where better to get a audience with Robinson 'experts'. AND you get to fly with one of the factory test pilots as well. When I was there I flew with Doug Thomkins the chief experimental test pilot, started with Robinson in 1982, ask for him or Tim Tucker, I'm sure either could demonstrate "anything" the robbie is capable of. And then there's Pat Cox who takes the maintenance side of things, knows his stuff inside out, and willing to talk about any subject at any level. If he can decipher my explanation of a mag failure and then explain to me what it was in such layman's terms that I knew exactly what he meant then he's a pro. And then whilst you're there Lu, you can personally discuss your opinions with Frank (and Tim Tucker etc.) at the same time... Just an idea ?
