Interesting.
When there is no pitch on, I can see that the single blade and weight will balance but as pitch is added, will the position of the thrust force will move out along the blade? There is more lift on the end of the blade than the root even when there is washout on the blade.
If it does this, it will act as as a cantilever on the mast causing severe vibration. The lift vector will not be central over the mast but will revolve around it.
The effective thrust vector must be centred over mast for no vibration. Tell me if I am talking rubbish.
On an Enstrom, 1/2 turn error on a pitch link is unflyable.
It matters a lot that tracking it is right. Small errors in dynamic balance are less noticable in flight.
Edited to remove really badly phrased bit.
