Design and development

The Stream is the company's fastest design to date. It was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, an enclosed cockpit with two-seats-in-tandem under a bubble canopy, retractable tricycle landing gear and a single engine in tractor configuration.

The aircraft is made from composite materials. Its {{convert|9.0|m|ft|1|abbr=on}} span wing mounts flaps. Standard engines available are the {{convert|100|hp|kW|0|abbr=on}} Rotax 912ULS and 912iS, and the turbocharged {{convert|115|hp|kW|0|abbr=on}} Rotax 914 four-stroke powerplants, driving a three-bladed PowerMax propeller.{{cite web|url = http://www.tl-ultralight.cz/en/ultralight-aircraft/stream|title = TL-Ultralight Stream|accessdate = 22 March 2017|author=TL-Ultralight |work =tl-ultralight.cz |year=2017}}

Operational history

Reviewer Marino Boric described the design in a 2015 review as "very sleek" and added that it "should give the pilot the feeling of piloting a jet-fighter."
