Slot Cars Rule !!!

Powering the track

  • Power Supply:

  • Of course all sets you buy come equipped with a wall wart transformer (or in a few cases in 1/43, with a battery pack), which is usually barely sufficient to run two standard cars on your track. One of the most annoying things with these (they are unregulated power supplies) is that when one car deslots, the other car will experience a surge in power and accelerate significantly (which usually leads to the second car deslotting). Also, these are not adjustable, thus you are very limited in terms of much you can change the cars and are pretty much stuck with the stock motors.

  • To alleviate these issues, upgrading the power source in your set-up is probably the best thing you can do (along with new/better controllers). In my case, I installed an adjustable regulated dual output supply capable of up to 3 Amps per channel, 0 to 30V. You don’t necessarily need such a fancy power supply as they are expensive, but voltage regulation and at least 1 Amp per channel/lane are a must such that your voltage does not fluctuate at all. Variable power supplies can be found from many slot car retailers or from places like DigiKey or BK-Precision.

  • Having a variable power supply in 1/43 is nice as Carrera Go! Cars need much more voltage (12-15V) than Artin cars (6-7.5V). It is also great if, like me, you have small children: you can set the voltage low enough so they can lap around the track at full throttle without ever crashing.

  • Another advantage of a power supply like the one I used is that it has an independent 5V/3A supply which comes very handy when you add some scenery and other accessories to your track.

  • You might also consider a Samlex (Read a good article on the Samlex supply), or Pyramid power supply (PS26-KX can be found on E-bay easily), or a CSI power supply.

  • Power Taps: I also added a few power taps on the track (a total of seven of them which is a bit of overkill); you really need only one every 20 feet or even less. For a good power tap article, check here.
