Thanks, that's nice ! toiletalker26, do you say that I should have put all the supports as true in the loop? I hesitated to do that but I found that it would have been overloaded the model... So that was a dilemma :p But I hold you suggestion ! About the connectors: I realised that my latest model hasn't connectors, so I tried to make it up for it !
^ I literally am curious as to where this coaster (to be this awesome track model) is coming from. Looks like Dorney's "Talon" to me because of the colors!
