Now that is some exelent scratchbuilding, the kitchen towl for the quilted lining wrks briliantly.
Also the weathering on the tail rotor looks perfect, it is not a chipping with sharply defined edhes but like what you did there a softer "sandblasted" look, well done :-)
Just as a matter of interest, I am not sure if the FAS does the same, the main rotor hub mounds and pitch links to the swash plate usually have color coded markings on them to show witch link goes to witch blade and the same for blade to rotor grip. It is usuallt no more than a red and blue band painted on them of about 1" (25mm) wide
Great work on your helli
