veryone, as my first instructable, this is a accurate remake of the Javelin Weapon system. The knex equivalent features a fire selector switch, (top attack, ground fire) safety, and quite a strong kick. The trigger is still a bit sketchy, but nothing a few mods can't handle ;). Anyway, on with the instructable!
This rocket launcher is very versatile and can be used in a variety of situations. For example, in a k'nex war, it could be used to destroy bunkers, or fortify positions.
Here is a video of the finished product. As you may notice, it barely leaves the barrel. This is due to the fact that I only used 1 weak rubberband. I have got it to shoot about 80ft, and with the size of the projectile, that is rather formidable.
EDIT: This thing has been rated 3.42?!??!? Are you serious!? Thanks guys :D
