If your aircraft is a Lynx it will not do this as the flying control runs have a Collective to Fore and Aft Cyclic interlink that will feed an increasing nose down cyclic input with increased collective selection.
Up collective > Nose down cyclic
Down collective > Nose up cyclic
IIRC it was to compensate for the fixed horizontal stabliser pitching influence on the aircraft to changes in vertical airflow at slow speed,I maybe wrong it's a long time ago since I played with a Lynx..
