Spin Doctor
Spin Doctor is a ride found in the Soaked! expansion pack of RollerCoaster Tycoon 3.
Construction
A single arm carries both a lower and higher car, each of which that can hold 2-4 passengers. The arm holding the ride spins, and the cars themselves can also spin. It moves at approximately 60 MPH.
In Real Life
The Spin Doctor is based off the Fabbri Booster, except it has two cars on each arm instead of one. A much similar ride was produced by KMG, named the 'Speed'.
