The Hubertec Thermik ({{langx|en|Thermal}}) is a German ultralight trike, designed and produced by Hubertec of Aach, Rhineland-Palatinate. 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 214. WDLA UK, Lancaster UK, 2011.

The company is an industrial prototyping and exercise machine specialist that decided to produce an ultralight trike design as a sideline project.
Design and development
Intended for self-launching and soaring flight, the Thermik was designed to comply with the Fédération Aéronautique Internationale microlight category, the German 120 kg ultralight class and the US FAR 103 Ultralight Vehicles rules.
The Thermik features a cable-braced hang glider-style high-wing, weight-shift controls, a single-seat open cockpit without a cockpit fairing, tricycle landing gear and a single engine in pusher configuration.
The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its {{convert|9.6|m|ft|1|abbr=on}} span Bautek Pico two-place wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a single cylinder, air-cooled, two-stroke, {{convert|25|hp|kW|0|abbr=on}} Simonini engine.
The Thermik has an empty weight of {{convert|48|kg|lb|0|abbr=on}} and a gross weight of {{convert|200|kg|lb|0|abbr=on}}, giving a useful load of {{convert|152|kg|lb|0|abbr=on}}. With full fuel of {{convert|15|L}} the payload is {{convert|141|kg|lb|0|abbr=on}}.
The aircraft can utilize any hang glider wing that can support {{convert|140|kg|lb|0|abbr=on}}, although the prototype used a Bautek Pico two-place wing.
An alternative version that fits a paraglider wing is also available, flying as a powered parachute.
