Something didn't seem right about this.
Empty weight of 100kg yet it has a range of 500km? Which it does in 3 hours, making the cruise speed upwards of 170kph, for something that's basically a powered glider?
Turns out that Wikipedia and AI are wrong here. If you go to the website (link below), there's 2 variants - 1 person or unmanned. The unmanned version has a 180kg battery, the manned version a 90kg battery. MTOW for both is 410kg (not 300kg), empty weight for the manned version, including battery, is 270kg.
Cruise speed is 90kph.
