The Verhees D-Plane 1 is a Belgian homebuilt flying wing, designed by Verhees Engineering and supplied as plans for amateur construction.Bayerl, Robby; Martin Berkemeier; et al: World Directory of Leisure Aviation 2011-12, page 125. WDLA UK, Lancaster UK, 2011. {{ISSN|1368-485X}}

Design and development

The D-Plane 1 features a cantilever mid-wing, a single-seat enclosed cockpit, semi-retractable tandem landing gear with small tail and wingtip wheels and a single engine in tractor configuration. Control surfaces include an elevon at the trailing edge of each wing and a conventional vertical stabilizer with a rudder.

The aircraft is made chiefly from sheet aluminum. Its very low aspect ratio {{convert|4.5|m|ft|1|abbr=on}} span delta wing has an area of {{convert|10|m2|sqft|abbr=on}}. The single nose-mounted wheel retracts while the tail and wing tip wheels are fixed. The recommended engine is the 1.6 litre displacement {{convert|50|hp|kW|0|abbr=on}} Subaru EA71 four-stroke flat-4 (boxer) automotive conversion powerplant.

By 2011 only the prototype D-Plane 1 had flown, but development work had begun on the design of the two-seat D-Plane 2. It first flew in early 2018, is powered by a {{convert|100|hp|kW|0|abbr=on}} Rotax 912ULS engine and cruises at about {{convert|250|km/h|mph|0|abbr=on}}.{{Cite news|url=https://www.aviatoruk.ga/europa-25th-anniversary-fly-in/|title=Europa 25th Anniversary Fly-in|date=2018-06-23|work=AviatorUK|access-date=2018-09-20|language=en-GB}}
