Decimator Crossbow (v7) Answered

Picture of

Well I finally got some more pieces, more still coming; this enabled me to build something bigger =d

This crossbow(more like cannon, now) has the following specs:

Ammo: 1 Standard arrow, which needs to be ductaped other wise torn to shreds.
Weight: 4,5 kilo's (9,92 pounds)
Range: Not tested outside, will beat the Reaper and the Blockhead for sure.
Rubberbands: 32, 8 strings of 4 ( these may still be increased as it shows no bending yet.)
Power: Just look at 2nd picture....should explain a lot.
Trigger: Same as on the Blockhead, some big improvements on it though.(Surprised about how power much it can take...)
Sturdiness: Seems close to unbreakable lol...
Without realizing..I also made a very good scope on it o.o

I had a purple+blue 3d connector as arrow tip and when I fired on my cardboard box, it made a huge tear...and my ears were ringing like from an explosion O.o'

Well this monster has bad points:
Need a long/strong left arm if you are right-handed, because this thing is heavy as hell.
Cannot fire without trigger.
Every arrow needs ductape otherwise connector gets torn off.

Also I gonna try and say...:

I think this may very well be the most powerful ranged k'nex weapon on this site at the moment.

Ugh never counted the amount of pieces.
I could have made it bigger..way bigger, but I wouldn't be able to turn it around in my room xD

The Reaper has it flaws, I could improve it a lot from what I have tried by now =o

keep it in a different room. or make it so you can disassemble and reassemble it.

There have been 600 comments on your instructables, forum topics, and/or your Orangeboard. Lol nice =D

Yeah that might have been an option, but I have two crossbows assembled right now, which are aimed at portability(and believe me...this one was hard as hell to even hold xD).

Holy ****. I have enough pieces to fill a 3'x2'x1' container (enough to have the Reaper, Heavy cannon V5, and some other pistols built at the same time) but there is no way I have enough pieces for that. A true work of art. Will be rated 5* by everyone I know once it comes out, I guarantee it.

I did have a small bit of knex over here...I ran out of green rods from this thing alone o.o'
But its just something I use indoors...or would be very suitable for knex wars, as the ductaping allows for even faster shooting.

And uh... those blue connectors on the center of the bow; the ones on top..should be purples =/
