In my views of Swan at previous Aero Friedrichshafen shows, the design caught my eye as it was (a) a single seater, (b) light enough to qualify as a Part 103 ultralight or its European equivalents, and (c) as it was an all-composite, nicely designed aircraft. Commonly, Part 103-capable designs are much more basic to remain within the tight limits. This statement also applies to the German 120-kilogram category or to Britain’s Single Seat DeRegulated (SSDR) description. As Aero contributor and Powered Sport Flying publisher Roy Beisswenger and I frequently discuss, the most likely place for electric propulsion to work today is in ultralights. This is because in very light aircraft with more local flying missions, battery weights for a modest period of flying (30-60 minutes) is already achievable in the very lightest of powered aircraft. We have been discussing this with FAA for more than three years.
Swan Ultralight Goes Both Ways: Electric & Gas
Swan (green) is seen with a clean electric motor installation at Aero 2017. The white one from an earlier Aero has a gasoline engine. Puppies are optional.
Radu and Modern Wings offer several varieties of Swan. One is a version with 115 kilogram (253 pound) empty weight which meets the requirements of the USA Part 103 regulation and those of Great Britain's sub-microlight SSDR regulation.
Another version with 120 kg empty weight meets the requirements of Germany's regulation.
"We ruled out all configurations that can be problematical for an inexperienced pilot," said Radu, to include a pusher engine and a tailwheel landing gear model.
Swan 120 — when a gasoline-powered aircraft — is a high-wing ultralight that weighs 240 pounds empty when equipped with a Polini 250 engine (the sort often used on larger powered paraglider).
