Tips and Troubleshooting

If the slingshot car is spinning out of control, then...

  • Make sure the wheels are attached parallel to each other.

  • Check if there is anything that's interfering with the rotation of the wheels, such as loose bits of hot glue or tape, or the frame of the car rubbing against the wheel.
