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

Step 1: Main Body (pt. 1)
Here is the first handle. If you can't build it from the pictures, please don't attempt this project.
Step 2: Main Body (pt. 2)
This is a continuation. A little bit trickier, but still if you cannot manage this, please stop now.
Step 3: The Rocket Tube!
This is the guts of the Javelin, this is where all the magic happens! If you can't build this, please stop now due to lack of logic.
(P.S, Please pay close attention to where the yellow connectors go...)
Step 4: Last Things
Just the fire selector and trigger. Basics! :)
Step 5: Putting It All Together
