This is a K'NEX buggy I've been working on for a few days now. I got a lot of inspiration from various builds I've seen on Instructables and Youtube. I've come up with a fairly simple build that should be easy enough to follow. The end product is pretty sturdy, and the independent suspension is a lot of fun to play around with!

I also fiddled round with adding steering, but I found you have to sacrifice sturdiness in order to do so. I will, however, publish another Instructables in the future showing how to add front steering for those of you who are interested.

As I write this article, I'm already thinking of improvements and changes. I'll be uploading an updated model soon I'm sure. Please feel free to comment with any thoughts or suggestions!

Step 1: Front and Back Suspension

Front and back suspension/wheel mounts are identical. Build 2.

These are a bit fiddly to get together, but they are the hardest part of the build.

I used No. 30 rubber bands.

Step 2: Body

Pretty straight forward, the purple flexible rods are the same length as a standard grey rod.

Step 3: Attaching the Wheel Mounts, Nose & Spoiler

Slot the back wheel mount in and fix on the spoiler to hold it in place.

Do the same with the front using the nose.

Step 4: Wheels

I like to double up, meaning you need 8 large wheels.

You could use white rods though if you only have 4 wheels.

Step 5: Make Your Own Improvements!

Now that you've finished the basic buggy, make your own tweaks and improvements! Please feel free to share them for everyone!

As I said in the introduction, I found that steering along with suspension complicated things and made the buggy not so sturdy. It broke a lot more frequently. But if you come up with a simple and sturdy steering system to complement this suspension system, please please link me to your solution!

Note: If you build out the body of the buggy more, you'll need to use more rubber bands to hold up the weight.
