The tips shared below are generally for racers who have not had a lot of experience with maintenance procedures of scale race cars. You will see below that modern slot cars are very easy to lubricate and tune and that taking just a few moments to oil your scale race car will make it run better, faster, and last a lot longer. We would like to hear from you too if you have something simple to add which isn’t already covered below. For even more tuning tips be sure to go to our high performance modifications page.
If your tip is well thought out, well written, concise, and clear we may use it.
Racing Tip – Handling
If your slot car fishtails and is constantly losing the back end on curves (especially the weaker magnet cars), simply clean the rear tires with a mild solvent or just rub the tires down with some saliva (yes saliva)! The car will immediately show amazing improvements in handling and significantly improve your lap times. (Santosh – South Africa)
Learn how to remove the slot car body for cleaning/maintenance
The bodies of most new slot cars are fastened from the bottom with two to four small Phillips head screws. Removal of these screws allows the body to be lifted off. This should be done periodically for chassis and gear cleaning as well as inspection of all other moving parts, even for checking the freedom of movement of the front guide pin.
This is a good time to do your oil/grease maintenance.
Tips on how to help your body posts last longer – When reinstalling the body screws if the screw seems tight as soon as you begin to tighten it, try turning the screw backwards a little bit and start it in a different position. I often find that the screw threads and body post have been mated to each other. If you start the screw in the right position and can find this same mating the screw will not rip plastic out of the body post when it is reinstalled. Also remember not to over-tighten the body screws. (in fact some slotracing pros say the cars run better if the body screws are left a little loose!) (DT)
Oil Motor and Axles
Oil…….change your oil every 3000 laps and use Mobil-1 synthetic….yeh right. Really though, OIL, used sparingly, is your friend and should be used periodically in several important places on every slot car. Oil makes every moving part work with less friction, less heat, and makes your slot car faster. Need we say more? Use your friend sparingly though because too much oil creates a mess, gathers more dirt, and seeps to places you don’t want it to go.
Using a light oil, such as hobby oil or sewing machine oil and a pinpoint needle oiler, you should periodically oil the electric motor wherever exposed armature shafts protrude, often times this is on both ends of the motor. Oil should also be …
