Well, to a point! There are only (to the best of my knowledge) 3
flywheel-launched Schwarzkopf shuttle loop coasters left in the world - the
rest are weight-drop driven.
(Montezooma's Revenge - KBF, Greezed Lightnin' - SFAw, Turbine - Walibi
Wavre... there may be a few in Japan, but I'm not sure if they're
weight-drop or flywheel)
In that system (I had a chance to ride one, Greezed Lightnin' at SixFlags
Astroworld in Houston last summer), a 6-ton flywheel rotates at nearly 1k
r/min, and engages a slipping clutch between that and the cable drive drum.
The skate pushes on a flip-up plate at the back of the train.
Montezooma's Revenge is also a flywheel-launched Schwarzkopf shuttle.
The weight-driven ones do not have as nice an acceleration. The acceleration
is more constant - the nature of the slipping clutch in the flyhweel driven
onces gives an EXCELLENT startup kick that really drives the train out fast.
