This is a simple dragster made with 3 main sections.
Creadit for the gearshaft goes to fobblewabble.
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!

not bad, but you should have made the design sturdyer.

jedff (author)dsman1952762008-04-06

i know

combot55 (author)dsman1952762008-04-03

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.

combot55 (author)dsman1952762008-04-03

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

dsman195276 (author)combot552008-04-03

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...

dsman195276 (author)combot552008-04-03

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.

gmjhowe (author)2008-04-03

Nice, but i agree, u shud work on making it more sturdy.
