The old 504e from an Armstrong CV500 fired up for the first time in years on the test bed this morning. This engine has been entirely stripped, cases all powder coated satin black. All bearings, rings, clutch, seals and gaskets all replaced and finished off with the gold coloured fasteners as Rotax originally supplied them.
