Lu Zuckerman,
Having read all the above posts can you answer the following for me:
How does a 'normal' semi rigid head i.e. a 206 compensate for lead lag? What is the difference between this and the Robinson? I asked the mechanics in the hangar but they don't know. From what I can see, although the construction is different, why should the principle of operation be different? Not trying to pick a fight, just a beginner trying to learn.
