Hope you enjoy racing them!

Step 1: Build the Gearshaft

Just build!

(The black connector can be replaced with 3 blue spacers.)

The motor is really slow, so let's make it faster! -->

Step 2: Build the Axle!

Just build again!
You need 11 silver and 1 blue spacer. (3 blues equal a silver just to let you know!)


Picture1: Complete

2: Left wheel. The thing next to the wheel is a tan clip. Notice the lone blue spacer.

3: Right wheel. The clip is still there.

4: Middle. See the gear?

5: Gear again.

Step 3: Build the Front Wheels!

Just build!

Silver and blue spacer, or 4 blues.

Step 4: Connect the Gearshaft and Axle!

Do what it says!

1: The parts.

2-3: How to connect.

4: Notice the mesh! IMPORTIANT!!!

Step 5: Connect the Body and the Wheels!

Again what is says.

Notice the way the motor angles to the wheel connections. ALSO IMPORTIANT!!!

Step 6: DONE!!!

Ok, now see the video for it in action. TURN UP VOLUME!!!



Ignore the china.

Yay! Original Dr Pepper bottles!!! (no period)

Hope you liked it.

This was just a quick project. fobblewabble made the gears, so i thought I'd try them out.

dsman195276 (author)combot552008-04-03

oh OK then. I might make this, but just a suggestion, change the small gray gear for a blue gear with a tan lock. the small gray gear is probely slipping some of the time making you lose some speed.

actually it never sliped for the 2 hours i was using it. the gears tight so it cant move that easly. plus i cant find that other gear

o ok. your grey gear must be stronger then mine.

combot55 (author)dsman1952762008-04-04

it takes a wrench to get it off a rod, so yeah... i think...

and change one of the catagoreys to K'nex.

I see it looks like it goes fast but it doesn't look much like a dragster (wich is good because of ho light it is.
