How to Create an Effective Drill Powered K'nex Coaster Launch

Hello everyone! I'm very glad I got this out in time, I was a little worried I wouldn't have time, but I managed it! This tutorial covers how to build a K'nex drill launch, with tips on how to make it more useful and efficient. I hope you all enjoy, and if you have any questions or need advice for your build, please feel free to ask in the comments! I didn't mention it in the video, but I do use a custom 3D printed gear for my drill launches, as the tan gear-to-axel connection piece can fail a lot without it. it isn't necessary for the launch, but it helps if you're low on parts and can't reinforce that connection any other way. Here's the link to the page to get the print file for the gear: https://www.printables.com/model/3574... Credit to the person that made this gear, it's such a good print for K'nex. #knex #rollercoaster #launchcoaster #themepark #build #engineering #coaster #themeparkride #themeparkride #fyp #fypシ
