Circular rubber band traction configuration with the fastest initial speed

1, choose a light circular rubber band, while ensuring elasticity and quality.

2. Try to reduce the weight of the trailer, such as reducing the number of rods and hooks.

3. Choose a trailer with low resistance, such as using a streamlined hook with optimized design.

4. Choose a high-speed car, such as a small and light model car.

5. Ensure the minimum contact area between the trailer and the vehicle, and avoid excessive resistance.
