To put this in perspective, a fairly typical 1.6kg hexrotor with NO payload will pull around 200W of electrical power in hover[1]. These guys are lifting 130kg with ~750W... [1]: 6.6Ahr battery @ ~14.4V, 95Whr of power. It'll go through that in slightly under half an hour, so it's pulling ~200W in hover. Small scale multirotors aren't very efficient. http://www.mikrokopter.de/ucwiki/FlugZeit#MikroKopter_als_Hexa-XL http://www.mikrokopter.de/ucwiki/FlugZeit#MikroKopter_als_He...
