Knex Battle Car - "The Base"




if you like this ceck out my group "knex battle cars" and post your own or see my future releases.

This a fun thing to do when you are bored, have a lot of Knex, but no rubber bands. this shows how to make a fun knex "battle car". me and my friends used to do this all the time. make two "battle cars" and crash them into eachother from accross the room, the first one to lose all thier wheels loses.
this is a very simple version of the battle car, and there is a million ways to customize it, i hope to see a bunch of different versions pretty soon.

It works best on flat sufaces (aka, concrete, hardwood floor, ect.)

oh and this is my first instructable, so critisize all you want, but be constructive, no "this sucks" unless you have a fortified reason.

DISCLAIMER - This has the ability to hurt people and or damaging property, and breaking knex peices, i am not responsible for anything you do to yourself, others, property or anything else you manage to destroy.

Step 1: Materials

here is what you will need.
by te way the wheels, mine only has three but you can use 4 if you want

Step 2: The Frame.

Just build the frame.
get the blue 3d connecters, two red rods (remember mine are green, i will be refering to them as red though)
and two yellow rods. attach them together as the picture shows.

Step 3: Add the Wheels.

Mine has three but obviously you can ad more if you want.

1. Add the wheels to the yellow rods, and use the red connectors as spacers. (you can use the blue rings too. I just didn't have any.

2. Just make sure they are at somewhat even.

Step 4: ADD ThE WEAPONS!!! (in Govonators Voice)

1. create one of the "hooks"

2. take anothe blue "3d connector"

3. attach two white rods on opposite sides.

4. next attach a green rod one slot over from one of the white rods.

5. attach two red corner connectors together as shown in the picture and then attach one white rod on the open end of the red connector.

6. repeat steps 2-5.

7. connect them together by a yellow rod.

8. and attach them to the whehichle on the one wheeled side.

Step 5: Create Some Defense

you will notice that the battle car is a little wobbly, so we need to add some support that will also work as some defense.

just create 2 of the first picture.

now add a little more suport by attaching a green rod on one of the open slots on the battle bot.


now this is a very simple version. i want to see a bunch more versions out there. i have keppt my best creations for a little while so if you want to see some of my 5 years worth of experience ideas, hen you must put up some of your own :). have fun!

    hey if you made 2 small block triggers from 2 rods, a few yellow connector and the block trigger each gun and mounted it on the car so that if another car hit it the car would shoot the ammo therefore totaling the other car

    add some remote controlled motors (an instructable on this site tell how to make em) and a steering system and then crash them into each other that would do A LOT of damage but you would need a LOT of support

    I used to do this when I was 10. My trick was to put alot of wight in the back of the car. The more pices the better. Very good work for your first Instructable. 4.0 :D
