How to Build a Strong K'nex Car.

These instructions will show you the top tips to building a strong K'nex car.

Step 1: Strong Axles

The first step to high strength is to make the axles strong. One longer piece of knex is better than two shorter peices with a join.

Step 2: Strong Front Frame

Make a strong frame on the front to prevent damage from front impacts.

Step 3: Strong Rear

Make a strong rear to protect from rear crashes.

Step 4: Strong Sides

Strengthen the sides to protect the main frame of the car. Most people forget the sides and pay the price later.

Step 5: Strength Bars

Build strength into the car by putting horizontal and vertical bars inside the frame. This stops the car from being crushed.
