After that there are those who learn how to fly smooth and those who learn how to correct their over correcting (If you can understand that) and fly under the false belief that they are smooth operators. 1000's and 1000's of hours doesn't seem to make them click. I personally think that it is retarded relationship with the rotor disk. It's really not that hard to realise and achieve yet it would have to be 6 or maybe 7 in 10 that do it.
