Aerones is behind some amazing drone experiments. It was only a few days ago that we covered their large drone which is capable of dragging 4 snowboarders. It is controlled using a remote control and has a max speed of 150 km/h. This video shows the Aerones drone pulling a wakeboarder at an impressive speed:
During this experiment, a top speed of 70km/h was achieved. Only half of the battery capacity was used over a 2.6km distance.
