Stan,
Concur with all advice given, but don't be too confused by matelo99 as there are significant differences between the Westland Sea King and the Sikorsky S61 about which he may not be aware. Fuel control/engine matching and control is far improved on the Westland product, so tq matching is far more stable. Also the references to Flight Drive starts is peculiar to the blade fold accessory drive which isn't usually present in the S61!
