The reason the fuselage hangs low is primarily determined by the position of the tail rotor in relation to the a/c`s CofG,Longitudinal,lateral and vertical. The moments derived by the t/r in producing "t/r drift" or "translating effect" have to be opposed by the moments produced by the rotor,and it doesn`t matter what type of rotor it is,rigid,semi-rigid,teetering,etc,those factors relate to sensitivity,response,and control power.If you are in a hover at fully fwd.c of g,and note the a/c attitude,then go to fully aft and hover, the a/c attitude will be more "left side down"(for CCW rotor rotn.)If you can now change the lateral CofG,you will now see an even greater variation in attitudes,and finally ,if you can find the vertical CofG and change it from it`s normal position,usually fairly high on modern helos,and use depleted uranium to lower it sufficiently(even as an u/s load-rigidly attached) and always using the same a/c weight,you can draw a matrix of attitude/weight(K)/CofG(lat/long/vert.).From the known a/c attitudes ,the position of the t/r relative to the a/c CofG can be ascertained and should show that an aft,high and left CofG will give the most adverse left roll!Of course ,if you are French and dress the other way,then you`ll roll right,and if you`re Oz then use a mirror-This ,of course could all be b*****ks,as this Chilean red is slipping down too easily,and I might have it all wrong!!!!
