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.Bayerl, Robby; Martin Berkemeier; et al: World Directory of Leisure Aviation 2011-12, page 84.

Design and development
The aircraft is derived from the Egon Scheibe Uli 1 and was re-designed to comply with the German {{convert|120|kg|lb|0|abbr=on}} 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.{{cite web|url=http://www.weller-flugzeugbau.de/node/14/62 |title= Weller Uli NG |last=Weller Flugzeugbau |publisher=Weller-flugzeugbau.de |date= |accessdate=2012-09-13}}
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 {{convert|9.68|m|ft|1|abbr=on}} span wing has an area of {{convert|12.78|m2|sqft|abbr=on}}, giving a very light wing loading of 17.0 kg/m2 (3.5 lb/sq ft). The standard engine available is the {{convert|30|hp|kW|0|abbr=on}} Briggs & Stratton industrial four-stroke powerplant with a V-belt reduction drive, powering a two bladed wooden propeller. The engine burns {{convert|5|L}} per hour at cruise. The aircraft's {{convert|18|L}} fuel tank is detachable for refueling and is filled with premium auto-fuel. The design incorporates a ballistic parachute whole-aircraft rescue system that includes an ignition cut-off upon firing.
