Want LEGO to make some sort of roller coaster set?
Support here: https://ideas.lego.com/projects/2201
If this reaches 10000 supporters, LEGO will consider making a coaster themselves, and then produce it so you can buy it in your local store!

It's here: my newest LEGO Roller Coaster!
Some facts:
5 cart inverted roller coaster train
10 minifigures per train
4 person staff
Half zero Groll followed by a half loop (diving loop thanks reissecup)
Total heigth: Track: 79 studs Overall: 95 studs
Track length of the track (measured from the middle of the track): 655,5 studs
Built on 4x2 baseplates (128x64 studs)
Powered by 1 Mindstorms NXT unit
3 NXT servo motors
3 NXT sensors: 2 touch and 1 color
working gates
