Light Helicopters and Tail Rotor Rolling Couple

[India Four Two]

crab,

Thanks for the detailed response. I first saw it early in the morning and decided I had better wait until later when I was properly awake, before trying to understand it

However, you mentioned something in your reply, which I had read elsewhere and I don't understand.

but in doing so creates a drift to the right for the whole aircraft

How does the tail rotor thrust cause the fuselage to drift to the right, when the force is being applied so far aft of the centre of gravity?
