The OAE XD147-1 was an experimental drone paper airplane designed by OrigamiAirEnterprises. The XD147-1 was the first drone paper airplane known to be equipped with canards. Until the OAE D203-1 Ascender was designed, the XD147-1 was the only canard-equipped drone made. The XD147-1 was lost during its original flight testing, but was later recovered in January 2012. In February 2012, OrigamiAirEnterprises restored the XD147-1 to flightworthiness for testing and evaluation. Data gathered was used for development of the Ascender. A modernized cruiser variant of the XD147-1 was developed as the OAE XD221-1. The XD221-1 was cancelled in favor of the OAE XD234-1, which was itself cancelled in favor of the much more advanced OAE D250-1 Starship.
