About:I'm a 16 year-old guy who loves to build mechanics out of knex. my main interests are ball machines and roller coasters. My real name is Matt and I'm a christian. I live in Australia or more commonly known as Down Under! :-) I am considered one of the best micro coaster builders on Instructables and will gladly help anyone who would like to start building them.

Making instructions for individual elements is not something that can easily be done because unless they build the element at the exact same scale, it'll be different to what you want.
My best advice is to build it in sections. Are you using tubes or box supports? I'd highly suggest starting with box supports as they are much easier to work with. Work on the first half-loop until you're happy with it. Look at heaps of pictures of real life cobra rolls and try to make it as close to the real thing as possibe. Maybe even try looking at other knex cobra rolls. The hardest part of a cobra roll is the valley between the two half-loops. make sure it's no too tight or the train will lose speed.
I hope that helped. Good luck with your building! :)
Hi, I know I have asked this question before, but I forgot the answer and can't find where I asked about it. :P What is the difference between green and orange (or other) colored micro K'nex roller coaster track? Thanks again. :D -salomon
