Nubian - you seem very quick to blame the pilot without being able to assess the conditions of the day.
A helicopter fuselage will tend to weathercock into wind - fine if you have decent airflow over the length of the fuselage but not at slower speeds. An aircraft with a bigger tail assembly (tail boom and fin) would be better but the Robbie has very little windage aft of the rotor mast.
Why else did they attach a drogue to the tail other than to try and keep it straight?
