This is my latest SM project, Batman and Robin. It is far away from a BTR clone and has G's of up to 4.2 if I'm right.
Elements it has:
Large Loop
Dive Loop
Zero G Roll
Cobra Roll
2 Corkscrews
It goes 55 MPH and it has 3 trains with each 8 cars.
Right no it is in the supporting stage so I'm barely starting to build them. The layout is complete and it is able to be tested.
Anyway here are screens.
