It may be unrelated, but during some Army reserve service in Bosnia 2000, we had some Czech Mi 17's located at the UK base at Banja Luka. One of the first things I noticed was the strange 'chook-chook' sound they make when running with lift pitch on. (Ground running, lever down; no noise).

Anyone encountered this or anything similar?
