Lockspeiser LDA-1


David Lockspeiser attempted to develop LDA (land development aircraft) general utility aircraft over two decades up to mid-1980s, with rear-mounted main wings and large canards, and rear-mounted engine with pusher propeller. A 70 percent-scale prototype flew 1971 as LDA-01, and intended full-size LDA-500 Boxer and larger LDA-1000 Boxer were designed.
