I'm on the final stages of building a Royal Navy Sea King HU5 from an old Airfix HAS3 in the Helicopters GB. The instructions for the HAS3 indicate that one of the main rotor blades is yellow but I wonder if this was only on the RAF HAS3's and not the RN HU5's. The walkround pictures and photos in my reference books either don't show it or don't seem to have it so I was going to go with Dark Sea Grey uppers and Medium Sea Grey lower surfaces. However, the instruction sheet for the Model Art HU5 transfers I'm using also indicate that one of the blades is yellow. I know there's a few Sea King experts out there in BM land and hopefully someone will be able to put me on the right track.
