Final Assembly:
Mounting Wheels and Hardware

Don’t overlook the importance of this stage. A huge factor in race performance is how smoothly the car rolls down the track. Some meticulously shaped cars have failed to finish races because of improperly installed hardware!
  1. Gather your hardware: two axles, two straw bearings, four wheels, four washers, and two screw eyes. Depending on the configuration of the car body, different hardware might be required. Shell cars (with internal wheels) often require wheel spacers and clips to affix the axles to the car body.

  2. Check your spec sheet for rules about wheels, axles, washers, and spacers.

  3. Wheel InstallationCarefully mount the wheels and axles as dictated by your design. Be careful not to damage the fragile car body during installation. Pitsco's new Wheel Deal is recommended for avoiding car damage while installing wheels and axles.

  4. Roll test the car on a smooth, horizontal surface. The car should roll freely, and the wheels should spin without restriction. Make adjustments if necessary.

  5. Screw Eye InstallationInstall the screw eyes on the underside of the car body. Important: Plan the location of the screw eyes so the guideline does not rub against the car body or wheels.
