Three Light Electric Motorgliders

Light electric motorgliders work well in the real world.  They’re light, compact, and easily transported to a flying site or back home.  Their small battery packs can be charged at home (under safe conditions) and provide enough duration to get the small machines to altitude, where they can explore thermals and ridge lift.  Because they are small, they require less materials and are often less expensive than standard-class or larger sailplanes.  Because they can self launch, they spare the cost of towplanes and possible chase crews. Economics aside, these craft provide fun flying and fairly untroubled ownership.

Something to Lighten the Post-Holiday Letdown

Even following Boxing Day, we have a few items to re-gift to our faithful readers, and close out the season with four very light examples of electric aviation. A-I-R ATOS Felix Ruhle has been improving and refining a basic wing design for over a decade, growing a line of aircraft that range from simple hang-gliders to fairly sleek, self-launching, electrically-powered ultralight sailplanes.  The A-I-R factory/showroom in Halblech, Germany, one of 18 dealerships around the world, fronts a lush green meadow and houses a plethora of ATOS wings. The ATOS wing, coming in a range of sizes, can be attached to seemingly anything from a simple jump-off-the-nearest cliff hang-gliding rig to refined, electrically-powered ultralight sailplanes. Under development for the last few …

Project ATOS Wing Explores Ultralight Electric Soaring

Its translucent wing shimmering on the wall above Hall A7 at Friedrichshafen’s 2018 Aero Expo, A-I-R’s ATOS Wing commanded the attention of show goers.  A-I-R (Aeronautic Innovation Rühle & Co GmbH) produces a line of ultralight hang gliders and electrically-powered craft based on a common wing design modified for different weight and performance requirements.  Note the large wing at about 35 seconds into this perambulation around Hall A7, along with tantalizing glimpses of the other displays that we will cover in the near future. Although ethereal in appearance, ATOS wings can carry significant loads compared to their minimal weight.  The 50 kilogram (110 pound) VRS 280, for instance, can carry an all-up weight of 330 kilograms (726 pounds), an impressive …
