Here it is, my newest project, FX-9 Crossbow. This is the second project in the FX-9 series.

Here are the facts:
Extremely sturdy ( dropped it from 5 feet and it survived)
Amazing range for k'nex ( 100 - 130 feet )
Uses a trigger like the reaper but it also uses a track
it weighs about 5 pounds
shoots a small but accurate bullet but you can shoot a number of different kinds

Tell me what you think

That thing is so thick that a real crossbow might be cheaper than the K'nex cost of that O.O

Is that good or bad? And why??
Killer~SafeCracker (author)  The Jamalam4 years ago

The ultimate K'NEX war ( using iconic knexers) TheDunkis: Ha! i have you with my UMP-45! DJ Radio: My OSSR has got YOU my friend! KILLERK: Ha! i have you both with my SR-V2! TheDunkis and DJ Radio: CRAP! Killer~SafeCracker: Uh, guys? Every knexer out there in the war: OH CRAP!
DJ Radio NYPA4 years ago
Range isn't a number 1 priority in a war.  ROF and accuracy are.  Then Reload times, THEN range.

a weapon that has good range will shoot hard and accurate from a strait range
Killer~SafeCracker (author)  DJ Radio4 years ago
True, so true. But it is a bonus.
Killer~SafeCracker (author)  NYPA5 years ago
Whats with the: Uh, guys??
You get there attention. and they see you with the "anchor".
Killer~SafeCracker (author)  NYPA4 years ago
  Ok.

You could chop down a tree with this thing!
Killer~SafeCracker (author)  Wafflicious5 years ago
Almost.
Lol, I'm a big fan of your guns even if I can't build them.
Killer~SafeCracker (author)  Wafflicious4 years ago
Well thanks man. MY next TNKIT entry isn't a gun but probably the most innovative thing I've made.
where's your house? ...oh, behind the crossbow!
knexguy5 years ago
You could kill someone with that thing... Without firing it.
Heart attack?
Possibly, I was thinking more melée style though.
Yeah, thats what I was thinking too.

Or dropping it off a high building on someones head...
yuo tont need a hi bilding gust guts
That'll go down as one of my all time favorite comments.
Ya a heart attack is what my dad had when he saw it.

An Villain5 years ago
should i build this?
Killer~SafeCracker (author)  An Villain5 years ago
If you have enough knex and you can build from the pictures be my guest. But if you can’t just wait till I post V 1.2
does not look hard just a frame that is a yellow connector thick and at the barrel 2 white connectors thick. it also has wheels on the bow. the only thing i may have to improvise is the trigger
Killer~SafeCracker (author)  An Villain5 years ago
Where is it a yellow connector thick?? The bow is 11 layers and the body is 3 layers on each the bottom and top. Also how many white connectors do you have?? If I recall it used somewhere around 150.
my bad i meant yellow rod. also i usually sub out blue connectors and other such things for them
IS THERE ANYONE ON THIS WHOLE PLANET WHO CAN BUILD THIS EXCEPT YOU?? HOW MUCH PARTS DOES THIS THING USE?????
I can.

I know many people that can.

FAIL
well looks good all i can say is HOLY CRAP THATS HUGE make sure you dont kill anyone by like wacking them lol XD
that would make a good fir support weapon

All that and only 1 rubber band string?!
Killer~SafeCracker (author)  pls5 years ago
As I said to Wickey you can add more but I was just running out.
Ohh. Post a pic of the trigger system :D

arrow shot5 years ago
a bit bulky dont ya think ;)? and uh, maybe you should add a handle? -.-
Killer~SafeCracker (author)  arrow shot5 years ago
It's not really that bulky for me. It has a Grip that molds to your hand, near the front but you can't really see it in the picture. As for the handle, I didn't have enough yellow connectors left because they are in my sniper
Wicky5 years ago
Wow that must be very sturdy, you could try and put more rubberbands on it?
Killer~SafeCracker (author)  Wicky5 years ago
Yes, you can add more rubber bands I was just running out of them.
The Jamalam5 years ago
hmmm... the only thing i like about it is the bulk of the thing. I rate this... 3 stars.
