Thanks Louis, having started painting the frames I decided to remove the molded wiper blades with help from my trusty #10 scalpel blade, 800, 1500, 2000 sand paper and mint scented polishing compound, pic 3 the wire mesh and brass tube tail rotor bush, pic 4 the modified rotor blade, now more paint on that windscreen, a few more details and it should be ready for a full coat of paint !
