Introduction: Loop. a Knex Roller Coaster

By
This is my second roller coaster. Also probably my last. I am going to start ball machines now.This roller coaster has a loop that is very sturdy. Let me know if you want more pictures of the loop. It is not hard to build though. I also might make an ible on how to make a roller coaster, but that won't be for a while.
Thanks for looking at this.
