Rotor past location

where was the rotor? Someone told me it is where chaos is today, but from ive seen, it looks like it was on the main midway... can someone help me out? thanks

There has been a Rotor ride both on the Main Midway and where Chaos is now. Not sure if it was the same ride or not.

Original Rotor was on the Main Midway from 1961 to 1964

I believe a New Rotor was in Chaos' current location from 1967 to 1984
