| Ever wondered what is going on inside your RC car or | | | | rear hub and axle pin since there is an obvious gap |
| truck each time you try to make it go forward, turn | | | | between the two materials. You have to first |
| and stop? These types of objects may be small but | | | | disassemble the parts starting from the rear hub and |
| there are a lot of actions happening at the time you try | | | | then the axle pin. Then, assemble again the rear hub |
| to make it move. How about what the things that are | | | | but this time, place the shim next (the shim could be |
| involved when you want to make your car go faster? | | | | plastic made, wood or metal) followed by the bearing. |
| What does it take really? | | | | Take note that the shim you will be putting should |
| If you want for your RC car to go faster during a race | | | | match the same dimension of the ball bearing to |
| or simply during an afternoon practice, the best and | | | | ensure that it will work properly. What the shim does is |
| very economical answer to that would be to use | | | | it minimizes the gap in between the axle pin and the |
| shims. What are shims anyway? A shim is a thin metal | | | | bearing. This should do the trick in making your RC car |
| or a wedge which can also be made of wood. It is | | | | run faster. |
| placed in between your RC parts to help the RC car | | | | There is one downside to shimming though. If there is |
| maintain its level just in case it goes over rough roads, | | | | too much shim, it's possible for the tires of your car to |
| large stones and the like. An RC car with shims | | | | bind. True that it won't slop any longer but binding then |
| reduces sloppiness while it runs. | | | | is going to be your next problem. So make sure that |
| The area where you can put a shim is in between the | | | | you don't use too much shim on your bearings. |
