That’s incredibly cool. I see they’re using an audio variometer to determine sink/updraft lift as well as using the solar-powered motor during cruise, and operate it as a glider during landing. Assuming they could fly it as a glider as well, although I don’t know how its low-speed performance is wrt. thermalling or stall characteristics.
