Micro K'nex Killer Kobra roller coaster Update 1
Hooray!!! Update!!!! Thanks to the people of instructables I have been able to make progress on my micro knex killer kobra. Thanks to your votes I have added a Zero-G roll. Apart from that I have added a cutback and a small hill. Now I have two more options for you to choose from. The last two pictures show what each one is.
Option 1: Barrel roll
Option 2: Helix
Just so you know right after one of these elements I will add a propulsion system that will hopefully give me enough speed to add a few more elements. The first element to get 4 votes wins.
