Canobie Corkscrew a clone???

I've been looking at old arrow loopers aka Corkscrews and the "Corkscrew" that was at Knotts is the same thing as the canobie corkscrew... same lenght, height, layout, etc. Also the Python at BGT is seemingly a clone and the Corkscrew at Salitre Magico is the same thing. Is this a clone and a lot of parks have them, so were they the Boomerang of the 80's???

i know that it was once in another park , maybe knotts.

Also Roller Coaster at MGM Dizzee World is the same thing as well. This "roller coaster" Was the one removed from Six Flags Worlds of Adventure in 1995...

Boomerang of the 80s??? Try the 70's!

It was inexpensive and compact....yup.

"I'll bet that thing hits 5 Gs going through that loop.....faaar ooouut!"

Canobie is accually a modified clone. It is slightly (unnoticably) different from Knott's (not Silverwood's) and BGT's. It is modified because it was accually designed to be indoors, with restricting space (back then it was the Chicago Loop)

I have no signature.

In case you want to see Canobie's treasure at it's former home, check these out:

It also operated at the Alabama State Fairgrounds between '82 and '86. Arrow built several Corkscrew models after the first one in '75 was a hit. Sometime around '78 they switched to support columns instead of the webbing around the loops.
