So the skype chat thought it'd be a good idea for a compact coaster. The template ended up being this:
Track must be in 10x40m from the top down view
Supports must be in the 10x40 below 5m, may only extend 3m above that
Station may extend 5m out from the template
Bonus points for over 140km/h
I'll be streaming my build in 20 minutes (1:30pm PST)
