The Heinkel 66 developed from the Heinkel 50, linking Aichi's commissioned dive bomber to work in Germany. Japanese payment helped provide cover for that German development. The Aichi aircraft is judged the better-built version on appearance, with the difference attributed to what Japan and Germany could afford at the time. That comparison is a visual assessment of build quality and budget, rather than a measured performance comparison.
