The Evolution of Tracks- The sections used to create the slot-car tracks on which the racers run have evolved considerably since the first ones were introduced. In 1957, at the start of this hobby, the tracks were made of rubber. Beginning in 1963, as plastics became more affordable, Scalextric began using plastic in the manufacture of their tracks (figure A). From 1963 until 2001, the tracks were made of a flexible plastic and were known commonly as Plexi tracks.
- The newest track systems from Scalextric are known as Sport tracks. They are still a flexible plastic, but the material has a different configuration for the connections --making it even easier for the sections to be fastened together. They simply slide together and lock in place (figure B) for quick and easy assembly. A typical new Sport track set takes about 15 minutes to set up, whereas the older style might take about 45 minutes. The new system is also set up with connections that are backwards-compatible with the older style of track, so hobbyists who still have the old style of track can still use it in conjunction with the new system.
- Another advancement in the newer track system is that the slots themselves are deeper, allowing 1/24-scale cars to be run on this track as well (figure C). With this system, a wide variety of slot-cars can be run on the same track -- from 1960s-vintage cars up to brand new models.
Slot-Car Maintenance
Modern slot cars are very low-maintenance, but there are a few tips that will be helpful in maintaining them for optimal performance to them to keep them operating over many hours of racing, and for years to come.
- Perhaps the most important area for maintenance is the part that receives the most wear -- the guide system (figure D). This is the part that keeps the car aligned in the slot.
- Scalextric developed the easy guide system, making it easy to remove the guides (figure E) and replace them with new ones. Where older system utilized lead-wires to connect to the motor, the new system utilizes only rubbing contacts and makes the guides a "quick-change" component. This design eliminates a main area of wear-related problems.
- Other areas for maintenance and potential problems include the rear axle. This can become a problem particularly when kids play with slot-cars on a carpet. The rear axle snaps out (figure F), making it possible clean this area and keep it clear of lint, carpet fibers, etc. You can also lubricate this area using a light machine oil.
- Through operation of slot cars -- and particularly after collisions -- the motor may pop out partially from its mount, and the gear-mesh may become disengaged. Simply press the motor down firmly to ensure that it is mounted properly (figure G).
- Slot cars also use a traction magnet mounted in the chassis. Most newer models have an adjustable traction magnet, so that it can be popped out and relocated within the chassis. For advanced hobbyists, adjusting the magnet forward in the chassis (figure H) will result in a "looser," more challenging racing feel -- allowing the car to slide more in the corners. Beginner racers may want to keep the magnet situated more to the rear for greater stability.
- Slot cars require occasional oiling, but the key is to use a lightweight oil and to apply only tiny amounts. Special oil dispensers allow a tiny drop of oil to be applied precisely in the tight spaces of the slot car's axles, bearings, etc.
- Apply a tiny bit of oil to each of the bearings of the front axle (figure I), and do the same for those on the rear axle.
- Occasionally, you may want to apply a very small amount of oil to the bearings of the motor (figure J). Use particular care to use only a tiny amount on the end that includes the brushes and the electronics.
- According to Alan Smith, there are high-performance motors and stronger magnets available from specialty companies to fine-tune and "hop up" these racers as your racing skills become more advanced.
Chris Chianelli's Mailbag
Q: Peter, a DIY viewer from Lansing MI writes: Chris, I have two pre-teen sons and would love to pass the fun that I had with slots on to them. I have a huge collection and I'd like to know what track will run all of these cars.
A: If you race 1/32-scale cars, those can be run on any Scalextric, Sport track, or Carrera track. If you want to run 1/24-scale cars (now made only by Carrera), it's recommended that you use Carrera track.
