This is Inertia. I began construction over last weekend; I didn't have any time to work on it before last night because of school (ugh!) but I managed to get it to finally do what I wanted.
This roller coaster is an Inverted Intamin; It's a launched full circuit, which I don't believe exist in the world today. Correct me if I'm mistaken. Inertia launches into a left turn at 45 m.p.h, and then right into a zero-g roll which is followed by a right turn.
This, in a sense, is the inverted [inverting] version of Rita: The Queen of Speed at Alton Towers in the UK!
