Radiusers

Radiusers are a type of roller coaster that features a central, vertical shaft around which the track rotates. This unique design allows for a variety of thrilling experiences, including inversions and high-speed loops. The radiusers are often characterized by their steep drops and tight turns, which can create a sense of weightlessness or even negative G-forces for riders. The most famous radiuser is likely the "Big Dipper" at Six Flags Great America, which features a 120-degree drop and a 180-degree loop. Other notable radiusers include the "Mystic Timbers" at Cedar Point and the "Racer" at Kings Island. Radiusers are popular among roller coaster enthusiasts due to their innovative design and exhilarating rides. However, they also pose significant safety challenges, as the vertical shaft can cause riders to be thrown outward during inversions. As such, radiusers are typically designed with safety features such as restraints and air bags to protect riders.
