The average person has probably heard of “slot cars” at some point in their life; while most may not know exactly what it is, slot car racing has been around since the 1930’s.There is a significant segment of the hobbyist population that races slot cars in competitions, and while popularity may have risen and dropped several times over the past eighty years, there is still a core group of enthusiasts who race these small-scale vehicles. Slot cars are considered to be “classic” and oftentimes, worth a good amount of money. Many collectables are often modeled after real-life vehicles, making them very valuable. Just as vehicles change shape and size over time, slot cars often imitate vehicles of their respective time period.
What is a slot car and how does it work?
A slot car is a miniature scaled automobile that is powered by a small electric motor. Scales include: 1/28, 1/24, 1/32, 1/42 and 1/64 or HO. The cars are raced on a track that has a groove for each vehicle lane, and the slot car has a small pin or blade that extends from the bottom and into the groove. The contacts for the electricity are picked up by the swiveling blade, or “guide flag” on the slot car, which provides the power to run around the track. The vehicle is controlled by a hand-held speed controller that filters in the voltage amount; the more that the trigger is pressed, the faster the car can go. The two types of controllers that are used are called analog and electric controllers. Analog slot car controllers allow the car to accelerate by distributing the desired amount of voltage to the car. Electronic controllers, unlike analog controllers, do not use the variable resistance method for power delivery, but instead use an electronic circuit to dispense the correct amount of voltage to the car. Because electric controllers offer improved control and the ability to command a wide array of cars, this type of controller is most recommended for a beginner.
What are the main parts of a slot car?
· Body/Shell – The top of the slot car is molded and scaled to a real vehicle. The shape actually does not influence the car’s performance, as it would for a real car. Instead, the mass and distribution of the weight affects the car’s performance.
· Interior – The interior often features a real driver and imitates the interior of the real, life-size vehicle. The driver and interior are typically modeled just below window height to allow more room for the motor. It is usually clipped or glued to the body shell.
· Chassis – The bottom part of the car is called the chassis, which is often one piece but can be made with a separate motor pod section. This piece attaches all of the other parts.
· Motor – The electric motor is what powers the slot car, placed at the front, middle, or rear of the car. It can be in-line, sideways, or at an angle. Like a real car, small gears transmit the power from the motor to the axle.
· Axle – The axle is the steel rod in which the wheels are attached to.
· Guide or Guide Flag – This is a plastic fin with the ability to pivot, which sits on the slot of the track and holds the braids.
· Braids – Copper metal contacts or copper braids provide power to the car by making contact with the rails on the track. It’s important that these are adjusted correctly for optimal car performance.
· Magnet – Front and rear magnets provide force to keep the car on the track.
· Chip – This refers to the circuit board which interprets signals on the track and operating the motor for digital cars. Some conventional cars have a chip to control the lights, but many do not have a chip at all.
What are slot car racetracks made out of?
Slot cars include a variety of other features and parts and differ depending on when the car was made and the maker. The majority of the slot car racetracks used for home races are made from molded plastic snap-together track sections. This allows the racer to reconfigure their track at will. The tracks used for competition are often hand-built; the guide slots for the vehicles are routed into a type of sheet material, generally either medium-density fiberboard or chipboard. Voltage supplied to the track by the power supply is typically between 12 to 18 volts and 1 or 2 amps.
What types of slot cars are best for beginners?
Cars of the 1/32 scale are most recommended for beginners, as they are very durable and are actually the most common size among hobbyists. The cars with very strong magnets are good for beginners initially, but may limit the development of driving skills. As racing skills develop further, the magnets are needed less and less and you may find you need to update your slot car as your skills progress.
What types of racetracks are best for beginners?
A simple track plan allows one to learn how to drive properly and enjoy the hobby. Sometimes an oval of track is best so that beginners can learn the fundamentals of accelerating, braking and controlling speed in the corners. A more elaborate and challenging track can be then enjoyed after some skill has been developed. Unfortunately, many sets do not have a good track layout for beginners. The beauty of plastic track is that you can configure a simple oval first, practice and then expand the layout with the balance of the track to make a more challenging circuit.
Clubs are a perfect way to get more involved in the hobby. Whether it’s a few people getting together informally to share tips and run their cars for fun, or large clubs that are a little more serious, joining a club will allow you to get the most out of slot car racing. Major competitions do exist on large tracks in commercial raceways, but these are typically for 1/24 scale cars, which require more sophisticated cars and equipment.
Slot car racing is a wonderfully diverse hobby that can stay with you for a lifetime and can be shared by generations of enthusiasts. Whether you’re a beginner or seasoned pro, there is always something new to keep you in high gear!
