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

 Here is the first handle. If you can't build it from the pictures, please don't attempt this project.

u hav a ps3 wit mw2,waw,black ops and red dead redemtion

 Isn't it obvious? You put the rubberbands on the top two yellows on the front, then pull it down so that it looks like it does in the video. Please use logic next time before posting dumb comments. ><
cool bas3 in reply to willdebeersMar 6, 2010. 10:46 PM

I know how to fire and how to make the bullet.
But i dont know how to attach the trigger to the rocket tube!

willdebeers (author) in reply to cool bas3Mar 7, 2010. 6:15 AM
 Its quite simple...There is one of those bendy connectors, you take that and click it onto the rod that goes down the side. Did you actually build it? Because if you did then you would understand.
cool bas3 in reply to willdebeersMar 7, 2010. 6:56 AM
OH THANK YOU! It works very good now!
Only the reloading is a  bit uneasy
willdebeers (author) in reply to cool bas3Mar 8, 2010. 9:53 AM
:D I know, it really is a pain. Could you maybe post a picture? I would like to see how it came out.

This would be a great gun if there was a picture of the assembled trigger. Unfortunately, there is not.
knexcannon says: Aug 18, 2010. 2:23 AM
i need help how do you attach the trigger
mettaurlover in reply to knexcannonJan 2, 2011. 4:02 AM
You don't. I've been trying to figure it out for days, and I still haven't gotten it to work.
DrWeird117 says: Jul 8, 2010. 11:15 PM
Wow. I've seen it all.
the poodleo says: Jun 4, 2010. 12:44 PM
no offense, but it kind of looks stupid, because on the video it only shoots a little bit in front of it before it plummets to the ground. that other video was awesome though.
Millawi Legend in reply to the poodleoJun 6, 2010. 8:54 AM
You didn't read the description then.
the poodleo in reply to Millawi LegendJun 8, 2010. 5:39 AM
well yah look at the first video though! i mena, it barely makes it out of the tube before it gos down.
Millawi Legend in reply to the poodleoJun 18, 2010. 1:33 PM
He said he used a really weak rubber band.

lol on the youtube window i went from ur gun's shot to a freakin A10-Gatling gun test
mettaurlover says: Apr 25, 2010. 7:37 PM
I tried to build this but couldn't figure out the trigger, so I took the barrel and attached IAC's V4 Heavy Cannon trigger to this and added a handle to the top so I could fire it. Haven't got a chance to fire the thing yet, but I've strung it like you would IAC's cannon without the actual bow. I have a feeling that it'll break stuff :D
mettaurlover in reply to mettaurloverApr 26, 2010. 12:12 AM
I changed the handle to be an arm harness of sorts so I can rest its weight on top of my arm and fire from that position. I think that my mods make it a more viable war gun, while using a comprehensible trigger. I also couldn't figure out your ammo, which I think is a worse problem than not figuring out the trigger, so I just used a random piece of ammo I threw together that fit and added a couple pieces so the trigger could grab it.

TigerNod in reply to willdebeersFeb 25, 2010. 9:51 AM
Intersting. I haven't seen an RPG-7 replica yet, so I'll be waiting!

Millawi Legend in reply to willdebeersFeb 23, 2010. 4:00 PM
The instructions are hard to follow and im stuck on the trigger. but is pretty cool still.
willdebeers (author) in reply to Millawi LegendFeb 24, 2010. 9:18 AM

Millawi Legend in reply to willdebeersFeb 24, 2010. 9:24 AM
