A video of the roller coaster Helix at the Liseberg amusement park in Gothenburg, Sweden, the largest amusement park in Northern Europe, using a homemade racing drone, is eye-catching.
If you look at the video, it starts with an aerial shot of the Helix Course. The drone is filmed while moving along the helix roller coaster course. It is said that this filming was officially cooperated by the Risebury amusement park, and there were no people on the helix for safety. Helix has many curves, as the name suggests, but the aerial footage using a drone gives a different feeling than what the passengers see in person. The maximum speed of the helix reaches 100 km/h. It is said that the acceleration of gravity applied to the body is 4.3G and there are three areas of zero gravity.
