Electric Flying Inspires Bigger Plans Dufour Aerospace, based in Visp, Switzerland, and within sight of the Matterhorn, has been flying aEro 1, a Silence Twister-based electric aerobatic craft, for the last two years.  Read the pilot report on the surprising performance and the quiet flight experience in the aEro 1 to get some idea of how future flight will be a welcome relief from the noisy today’s noisy passage.  “Electric motors are so incredibly efficient. They have a huge torque and you will take off much faster than with regular engines. Our aEro 1 takes off after 70 meters of runway – at 2/3 of the available power. “The first real takeoff and flight afterwards was really mindblowing. I set …

Another Cure for Range Anxiety

Or at least an approach to provide angst-free cross-country flying, as Michael Friend explained in his Electric Aircraft Symposium presentation last April at Rohnert Park, California.  Friend, a Boeing engineer closely tied to the company’s early fuel cell work, is the owner and pilot of N787M, one of the earliest production kit Silence Twisters.  The Twister is a Spitfire-like, retractable-gear light aircraft capable of cruising 146 on its Jabiru 80-horsepower engine.  It’s capable of full aerobatic flight, and was converted to electric power in Germany for possible airshow demonstrations.  The Twister’s designers also plan a lengthened wing that would make motor gliding possible. Friend noted the difference in energy density between available batteries and gasoline, explaining that 10 kilograms of …
