Weller ULI NG
German ultralight aircraft

The Weller ULI NG (New Generation), sometimes called the Weller Uli NG, is a German ultralight aircraft, designed and produced by Weller Flugzeugbau of Bibersfeld. It was introduced at the Aero show held in Friedrichshafen in 2010. The aircraft is supplied as a complete ready-to-fly-aircraft.
Design and development
The aircraft is derived from the Egon Scheibe Uli 1 and was re-designed to comply with the German 120 kg (265 lb) class ultralight rules. It features a cable-braced high-wing, a single-seat open cockpit without a windshield, fixed conventional landing gear and a single engine in pusher configuration.
The aircraft fuselage is made from welded steel tubing, the wing built from bolted-together aluminum tubing, with its flying surfaces covered in aircraft fabric. Its 9.68 m (31.8 ft) span wing has an area of 12.78 m2 (137.6 sq ft), giving a very light wing loading of 17.0 kg/m2 (3.5 lb/sq ft). The standard engine available is the 30 hp (22 kW) Briggs & Stratton industrial four-stroke powerplant with a V-belt reduction drive, powering a two bladed wooden propeller. The engine burns 5 litres (1.1 imp gal; 1.3 US gal) per hour at cruise. The aircraft's 18 litres (4.0 imp gal; 4.8 US gal) fuel tank is detachable for refueling and is filled with premium auto-fuel.

Why this record matters
“Weller ULI NG” is worth following because a concise public description often conceals a longer documentary argument. Here, Weller, German and ultralight provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 9, 2025. The linked authority identifier is Q7981220. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2010.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
