This is rather analogous to Patent FR-1910-424466 and therefore ultimately descends from the purported Patent AT-1909-12-31 Vigilio Baldo. We'll have to get back to this, but it has to do with, among other things, independent motors, attached to separate propellers, specifically in the interests of safety.
