4d Fly Coaster "The Joker"
The Joker is a 4d fly roller coaster at Six Flags over Texas. It was opened in 2016. As a rider of the real ride, I decided to submit a working Lego version. The seats rotate to give a unique feel to the ride. The real thing, priced at 7,000,000 USD, is a very modern roller coaster. My Lego version features:
-working track and runner system
-8 minifig capacity
-sturdy, playable design
As a rider, I think this would sell well because of the popularity of this ride.
