One of our little quadrocopters, 'Echo', took some time off from her busy little schedule one evening and decided to play a little something for the holidays :-) We wish you a Merry Christmas and Happy New Year!! Created/filmed at the Flying Machine Arena, IDSC, ETH Zurich, Switzerland. For more info: http://www.flyingmachinearena.org by Sergei Lupashin, Markus Hehn, Angela Schöllig and
