Introduction: Knex Faster Car Idea.

Picture of Knex Faster Car Idea.

This motor and gear idea will show you guys how to make a faster car. How faster you might ask?, more than two times faster. In this instructible I used a low-class motor found in the starburst spinner set. It is one of the slowest motors.

Step 1: Wheel Rod

This is the wheel rod.

Step 2: Motor and Big Gear

Step 3: Adding It All Together

Add it all together.

Make the Wheels bigger as well. Here is a car that I made a few years ago with a gearbox to make it faster.

if only you could post instructions for that :P

Coolio!! I like that!

Good idea, but the problem is that this will also reduce the grip on the ground. But it's nothing to worry about as long as the gears are not too big.

Nice idea. This is in my instructable. (I gave you creadit, so don't worry!)

I made a fast car without the big yellow gear I used flames1039's theory I did the the yellow(small) the gold twice. good result

Mepain do still know how to make that car? If you do please post it because it looks sooooooooooo cool

It is faster, but the torque is so low that it's useless.

fobblewabble (author)2007-12-24

its just an idea... but mepains actually looks like something. my looks like a piece of crap.

flames10391 (author)2007-12-23

its easy to make faster gearboxes if you know the ratio between the gears and the order you place them in small, big, small, big, etc... will give you torque big, small, big, small, etc... will give you speed

the properties of gears i stated above are valid for all gears...not only knex

dramamine (author)2007-12-23

Eh, I don't know what this would do but it seems.. useful, I guess? I have a different motor and gears so I can't test it.

it doesn't go fast just keeps going...

Daniel662000 (author)2007-12-23

hmm not that fast.
