## Discrepancy

DURING POST MX FLIGHT CHECKS, THE PILOT SAID SMALL INPUTS TO THE COLLECTIVE RESULTED IN LARGE MOVEMENTS TO THE ACFT.  THE ENG TORQUES WERE ALSO DIFFICULT TO STABILIZE.  AFTER LANDING, SHUTDOWN & INSPECTION BY MX, A LAG OF COLLECTIVE INPUT TO THE MOVEMENT OF THE MAIN ROTOR BLADE WAS NOTICED WHILE OPERATING THE HYDS ON THE GND.
