Start up and take off with the RES flight model made of wood "GezoRES" under weak conditions:
~ 1Bft and hardly usable thermal.
Wingspan 2 m
Flying weight in video 710 grams
Thanks to Paralaxe the model has won the speed comparison with the Boeing 747 in the approach to Frankfurt seemingly, but surely the GezoRES can still fly better than the Jumbo 😉
