New Record Breaking Three Inversion Backyard Coaster – Tilley’s Terror

After a lot of thought and planning, I’m going to do it.

After seeing the John Ivers’ Blue Flash, I’ve wanted to make my backyard coaster with an inversion. After looking at a vertical loop, I decided it would be too tall to construct on my land for it to be smooth and safe. So I abandoned that idea.

Then I saw Will Pemble attempt a barrel roll. That looked like it hurt tremendously….challenge accepted.

But why stop there? If I make it a shuttle coaster, I can get 2 inversions for the price of one.

But why stop there? Instead of a spike, why not a scorpion tale? There’s only one of those around…

In conclusion, I am making a 3 inversion backyard coaster with a 25 mph Dragster style launch and professional control system. It will be ledgendary!
