Good point re drag dampers Paco - a friend of mine on an early morning walkround didn't spot that the groundcrew had wrapped the red and white flag attached to one of the drag dampers on a Wessex around the drag damper so it was very difficult to spot - it padded a little on rotor start (not unusual) but when he lifted to the hover it was very obvious there was something badly wrong. He ended up having to do a running landing and chop the throttles while rolling since it just bounced way too much on a vertical landing.
