Mmmmm ...
Like the Bolkow 105 ... the Lynx has a 'Rigid' rotor ... and as said above a short mast ...
In fwd flight the T/R is clear of the rotor airflow by being above the downwash.
And apart from inflight Aero's etc .....
Rotor clearance problems can arise with touchdown autorotations (like with the blo cow) it is possible to chop the tail because of blade flex at low Nr especially if it is kicked up by an over 'positive' touchdown.
