Picture of The H.V.I Cannon S-GR 2280

Check my Wall-E Garbage Bot too!

My sweet new cannon!
It has outstanding power, looks and has a crazy range!
About 80 ft!
I do think this is one of my biggest guns ever even, bigger than the A.D.U!
This was supossed to become the V2 for the A.D.U but it now has wheels so i can't really call it a V2.
Anyway, great gun and a must for everyone (with a lot of pieces) with nothing to build!
Now for some pros and no's:

-Awesome range
-Looks great
-Very powerful
-Drives smooth
-Scares anyone instantly

-Very high part use (view parts list)

You likey?
Let's get to building then!

Build it 1 time.

On of the most interesting parts on the gun since,
it's upside-downed.

Dude, you really need to make some more detailed instructions and more noob friendly

knexsniper1 (author)2009-08-19

im scared...

Skreetsha (author)knexsniper12009-08-20

Lol, don't be, just never point it at yourself, made that mistake myself. Big ####ing bruise on my arm for 2 weeks, lol. Gotta have some pain for the K'nex building X)

shieldsam (author)Skreetsha2011-12-20

no pain, no gain

Skreetsha (author)shieldsam2011-12-22


Knexman15 (author)2011-08-30

Are the green rods under the yellow connectors essential???

Skreetsha (author)Knexman152011-09-19

Yes, that's how you mount the bottom half and the top half together.


Knexman15 (author)Skreetsha2011-09-23


knexpeople (author)2010-03-10

I mean, you should ask him first

knexpeople (author)2010-03-08

Why dont use IAC,s original missle?

Skreetsha (author)knexpeople2010-03-09

Because i don't copy people.

chazman2 (author)2009-10-10

if it wurcks whats the range of it

Skreetsha (author)chazman22009-10-10

Speak normal English, and i will reply.

BuilderLoon (author)Skreetsha2010-02-10

If this Knex Cannon works, Then what would the range and accuracy be on it?

knex luver123 (author)2010-02-08

in every knex cannon/ bazooka i have made, i can always find ways to make the stronger

Fred the Penguin (author)2009-08-02

problem with your first picture the rubber bands are right in front of the barrel

They are supposed to be like that.

wouldnt they get in the way?

Apparently no, because almost all knex annons have them near the front of the barrel, as i show in Viccie.B1993's other cannon:

no they dont thoose are the bands for the pull back(as far as i know)

agent harmsy (author)Hiyadudez2009-09-07

Except when I built it, they DID get in the way! T'was quite annoying, so the gun only stayed built for about 2 days...


mettaurlover (author)2009-10-05

i have GOT to build this out of micros.

Hephestus (author)2009-09-19

your ible' reminds me of "I_am_Canadian" cannon

Skreetsha (author)Hephestus2009-09-19

Alot of people before you already pointed that out, but it wasn't supposed too, it just came out looking like that.

glugnar (author)2009-09-01

not very high self esteem

Hiyadudez (author)2009-08-19

Are they rubberbands or string?

BuilderLoon (author)2009-08-15

I gave my friend an old tv and he gave me 2 full boxes of KNEX KERCHING!

marlonlaija (author)2009-08-05

boggstown (author)2009-07-28

Help if you can. Man this is hard.

I_am_English (author)2009-07-21

I_am_English (author)2009-07-21

no hahahaha lol

I_am_English (author)2009-07-21

can i use yellow connecters for the barrel because I built every thing else but the barrel and I thought I would have enough

An Villain (author)2009-06-23

not enough grey connectors for ammo! can i use anything else?

Skreetsha (author)An Villain2009-06-23

Sure, you can use those 2-side greys, or even red connectors, i guess.

An Villain (author)Skreetsha2009-06-24

thank you, by the way this is the most piece efficient cannon other then logic boy's but this is cool, and i will build.

Skreetsha (author)An Villain2009-06-24

Uhm.. not trying to annoy you but, i think the ADU is more piece-efficient. But thats a bazooka ;)

An Villain (author)Skreetsha2009-06-24

the ADU is actually a shoulder fired bastille because it fires an arrow-type projectile.

bighead5454 (author)2009-06-24

will different size wheels work other then just some small ones will large ones work too?

Skreetsha (author)bighead54542009-06-24

The wheels are not required, i just putted them on for some extra beefy look :P But i guess you can use normal sized wheels too :)

killerAP (author)2009-04-01

ok how big of a dent does this put into your walls? also you should put some flattened cardboard boxes and see how far it goes through them. I cant build this cuz i only got, oh, say, 1% of the total pieces you have. any idea where I can get tons more!

bighead5454 (author)killerAP2009-06-24

you can get great deals from ebay or amazon i recommend amazon cause it has a quicker checkout

interman (author)killerAP2009-04-04

To: killerAP From: interman I know where you can get more. At local Wal-Marts, Targets, or any other store in the toy section.

sprout_less (author)interman2009-04-07

no way i got 3,000 pieces off ebay for 37 dollars

Nice, i got 2,500 pcs. off ebay for ~$25.00

yah its so cheap i will probably get more soon the one thing that sucks about knex of ebay is shipping

Skreetsha (author)killerAP2009-04-02

Well, i never fired it at my wall, for well... quite obvious reasons but, it left my knex box pierced so it is really powerful! And if you're in Holland, i don't know where to get K'nex except for Toys'r'Us but it's pretty exspensive and not that much K'nex per box. If you're in England, America wherever els, i can only think of Ebay.

killerAP (author)killerAP2009-04-01

where i can tons more at a cheap price?
fixed it
