Thanks Mathew.
You have answered my question on Pendular action very well.
Thanks again.
On the controls reversed question, I was told by an old Ex Vet buddy that flew UH1's and did some time in Chinooks that the forward and aft ( from what I remember of the conversation which was years ago....and I may have been inverted due to the number of drinks consumed that weekend ) inputs on the chinook are reversed , being that a flare ( aft cyclic produced a nose down attitude and a for cyclic input created a nose up result ) and did create quite a scare for the pilot that was transitioning from single mast type helos.
This also may have been whilst there was little or no airspeed or out of ETL... I just cant remember the whole story.
Now saying that , I am not sure if that was something that was from back in the day designs or I misunderstood that statement or he was just leading me up the garden path for a bit of fun as good mates do , though I dont believe he was having a lend to be honest, though thats when mates usually do get you dont they !.
Cheers
