Production aircraft would have been optimised for production and also used new manufacturing techniques, particularly for the wings, which were intended to be built using the hollow shell method; high-accuracy plywood skins laid up in jig moulds with structure added in the mould to retain the high accuracy surfaces.
[1] Construction was of welded steel tube for the fuselage with wood for wings and empennage.
