I did the two with the instructions, then I did a couple on my own.
First was a Corkscrew which turned 180 after the lift, then dropped and the corkscrew went under the lift, but the car cleared the chain!!! Then it had just enough momentum to get back to the lift! The second was just a huge drop starting at the top of my stairs. It did an S:ROS tun at the bottom and went into a HUGE loop, then a nice helix. Lots of speed!
