Aero, an annual event at Friedrichshafen, Germany, highlights the beginning of the European air show season.  E-Flight Expo has been a regular part of this for the last several years, and displays the latest in electric flight technology.  Certainly the most forward-looking part of the show, the Expo grows every year.  Several exhibitors helped further the advanced look this year. MGM Compro With at least five aircraft powered by their electric power systems on display, MGM Compro showed great market strength.  The Czech firm has 16 of its motors atop each Volocopter 200, with one as a propulsor in the tail.  Their motors power the Magnus e-Fusion aerobatic trainer, several GP gliders, the S.R.O.

Irena Raymond shared the following about her and huband Eric’s flight across the Alps from northern Italy to Switzerland and return – a four-day tour of the mountainous country, and validation of the Sunseeker Duo’s performance. The latest of a series of accomplishments, the trip’s mission was to “stop and show the airplane at different airports,” according to Irena. Remember that Eric crossed the United States on solar power in Sunseeker I in 1990, 23 years before Solar Impulse managed the feat. Eric crossed the Alps on his way from Friedrichshafen, Germany to the World Air Games in 2009, guiding Sunseeker II over sometimes cloud-shadowed peaks. Now he and Irena have made a two-person Alps crossing and tour of the …

Erik Raymond is moving his shop and Sunseeker Duo project to Voghera, Italy, nestled in Northern Italy between Milan and Genoa.  He showed the completed airframe at this year’s Aero Expo at Friedrichshafen, Germany and discussed, no doubt, the future of electric aviation with Axel Lange, the CEO of Lange Aviation.  Lange has developed the Antares and Arcus electric motorgliders, both outstanding designs. Following the Expo’s finale, Erik and his wife Irena drove south to Italy, where their enterprise will complete work on the Duo and plan for their proposed trips in unexplored realms– all on solar power. With Solar Impulse crossing the United States (which Erik did in 1990 in Sunseeker I) and more flights planned by other participants, …

The Kindest Cut of All

In 1811, an inventive tailor in Ulm, Germany attempted a hang glider flight across the Danube River.  He failed in the attempt, but it became the stuff of legend and at least one television commercial.  Albrecht Ludwig Berblinger (1770-1829) had wanted to be a watchmaker, but was consigned to become a cutter of fabric.  Despite this, he used his spare time to invent things like the first jointed artificial leg in 1808. Perhaps his skills with fabric led to his fabricating a pair of wings, essentially a hang glider, Shunned by his fellows for working outside the discipline of tailoring, Berblinger poured his resources into building and testing his glider.  Leaping from a scaffold built for the attempt by Prince …
