The latest new installation (i.e. not relocated) was Queen Cobra at Sun World Danang Wonders in Đà Nẵng, Vietnam which opened in 2017.

[5] Once at the top, the train drops down a steep, banked right turn where it enters the first inversion element - a right rollover.

[7] After exiting the sidewinder, the train navigates a 270o right upwards helix before entering the ride's final two inversions - a double inline twist.

At this point, some models feature an additional helix to the left, while others simply continue straight into the brake run.

The only four known places to have these trains are Morey's Piers,[9] Isla Magica in Spain, Six Flags New England in Agawam, MA and Beto Carrero World in Santa Catarina, Brazil, along with Nopuko Air Coaster at Lost Island in Waterloo, Iowa.

In 2012, Lethal Weapon - The Ride at Warner Bros. Movie World reopened as Arkham Asylum - Shock Therapy.

The newly opened ride runs with trains manufactured by Kumbak and uses less restrictive harnesses which are similar, but not identical to, the vest-like restraints found on the SLCs at Morey's Piers and Isla Magica.

For example, the "Hanging Roller Coaster" at Crab Island stalled before its sidewinder element, stranding 12 people for over 3 hours.
