Tine Tomazic of Pipistrel alerted the blog that his firm started series production of their Taurus Electro G2, a first for a two-seat electric aircraft, according to Pipistrel, claiming 20 customers who will receive their G2’s by year’s end. Improvements over the prototype led to the “rev.2” series version of the self-launching sailplane, which also is the first electrically-powered craft to exceed the performance of its two-stroke Rotax-powered alternative, according to Tomazic. Pipistrel expands on this.  “Taurus Electro G2 can use a shorter runway, climbs faster and performs much better than the gasoline-powered version when it comes to high altitude operations. All this is possible thanks to the specially-developed emission-free Pipistrel 40kilowatt electric power-train.”  The clean sailplane design (40:1 glide ratio) allows full exploitation of the system. Improvements in the motor and batteries contribute to this performance boost.  The new motor weighs 11 kilograms (23.2 pounds), five less than the prototype’s unit, and generates 10 kW more power.   Pipistrel notes, “Due to this …

The Pipistrel folks in Slovenia have been producing some suprising aircraft with surprising names for the last two decades.  Their Virus and Sinus motorgliders are well-traveled and well regarded, having won honors in the 2007 Centennial and 2008  General Aviation Technology Challenges sponsored by NASA and managed by the CAFE Foundation.   The firm recently announced that it won the European Business Awards prize as the Most Innovative Company in Europe – out of 15,000 entrants.  Indeed, their real-time posting of their solar-powered factory’s electrical output is a strong reminder of that drive to create new paths to the future. Another reminder of Pipistrel’s creative juices is the picture of their four-seat hybrid aircraft, which should be flying in the new year, according to Tine Tomazic, part of the company’s research and development team.  Tine confirms that the aircraft will cruise on 160 horsepower at 200 knots (230.4 mph), is a hybrid – although not a parallel hybrid, and that its “performance will definitely …
