The Top Spin is a thrill ride developed by HUSS Park Attractions, and is the generic name for a series of rides from other manufacturers that follow the same principle. The ride consists of a passenger platform suspended between two counterweighted arms. The arms are turned by motors, while the platform usually only has brakes that are engaged and disengaged at various points of the ride cycle. A typical Top Spin program runs the main arm motors while engaging and disengaging the platform brakes so that it will rotate in exciting ways. The minimum rider height requirement is 54 inches, and the maximum is 80 inches, due to the seat and restraint design. The ride was first introduced to the public in 1990 on European fair circuits.
HUSS has designed the ride so that park and carnival operators may choose one of eight preset ride "programs". Most last no more than two minutes and consist of several moderate-speed flips and face-down "hangtime", before unlocking the gondola hydraulics and swinging the riders back and forth. Some Top Spin rides have the added feature of water fountains, which are mainly used at the end of the ride sequence, soaking the riders as they are slowly lowered face-first into the jets. Cycles can be customized to include more intense repetitive flips, and also can be put under manual operator control. A world record was set with over 100 gondola flips during a cycle on a Top Spin in Germany.
There are numerous other Top Spin-inspired ride models that were later developed by other manufacturers. Some of these variations of allow each individual arm to be controlled separately, creating diagonal gondola inversions. Various examples of Top Spin-inspired ride models include "Windshear" by Zamperla, "Super Loop" by Moser's Rides, "Waikiki Wave" by Vekoma, "Super Nova" by Mondial, and "Discovery" by KMG.
The Top Spin was once a common ride at travelling carnivals, particularly in Germany. Over time, many of the travelling versions of the ride have been sold to amusement parks or put in storage indefinitely.
