The Hydropteron was first flown on 25 November 2009 and introduced to the public at the AERO Friedrichshafen show in 2010. The aircraft is intended to be supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.<ref name="WDLA11">Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 60.

==Design and development== The aircraft was designed to comply with the US light-sport aircraft rules in its two-seat version and amateur-built rules as a three seater. It features a cantilever high-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, with a third seat optional, a cruciform tail, retractable tricycle landing gear and a single engine in pusher configuration.<ref name="WDLA11"/><ref name="WDLA15"/>
The aircraft is made from composites. Its {{convert|10.9|m|ft|1|abbr=on}} span wing, has an area of {{convert|12.47|m2|sqft|abbr=on}} and flaps. The standard engine is the {{convert|115|hp|kW|0|abbr=on}} Rotax 914 four-stroke turbocharged powerplant, but engines of up to {{convert|140|hp|kW|0|abbr=on}} may be fitted. No wingtip floats are fitted and the aircraft relies on fuselage-mounted sponsons for water stability.<ref name="WDLA11"/><ref name="WDLA15"/>
Production was originally scheduled for 2011, but as of early-2017 only prototypes appear to have been flown.<ref name="WDLA11"/><ref>{{cite web|url = http://www.ideaaircraft.eu/index.php?menu=howtobuy|title = How to buy|accessdate = 2 March 2017|last = Idea Aircraft|year = 2017}}</ref> <!-- ==Operational history== --> <!-- ==Variants== --> <!-- ==Aircraft on display== -->
