Traction refers to the resistance or friction happening between each tire and the ground surface. More traction allows your car to turn at higher speed without losing control. Technically speaking, traction is the result of the following factors combined: – the friction between the tire and the ground – the area of ground covered by […]

The traditional type of drive shaft kinda reassembles a dog’s chew bone and is often being referred to as the dog bone shaft. An enhanced type has a pivot type joint on one end and is often used in professional racing under a ball diff configuration. Measurement is either pin to pin or end to […]

Pro racers always dislike the idea of large bumper due to concern on weight. For beginners, however, a large bumper can protect their valuable first time investment, at the expense of slight weight increase (which wouldn’t matter much for them anyway).

Due to the fact that most R/C cars have their motor placed closer to the backend of the chassis, the rear and front ride heights tend to be uneven (the heavier side goes lower). An artificially configured “lower front” can benefit steering but is easier to go “diving” (which can make the car slides) when […]

The more components you load on the chassis, the lower ride height you are going to have. A low ride height tends to give better stability and is generally good for touring cars. For buggies running on bumpy roads, a low ride height may mean frequent chassis breakage.

Generally speaking, there is no need to use locktite on a brand new R/C car unless the car is going to run entirely on bumpy tracks (meaning the car is going to shake excessively all the time). Frequent disassembly can make things loose, therefore you may need to apply locktite accordingly. It is especially suggested […]

If you find yourself confronted with a screw that is extremely difficult to get unscrewed, don’t use brute force (or you risk stripping the threads). Instead, give the screw a slight twist in the opposite direction and then loose it again. If this does not help, tap the screwdriver on the head with a small […]

Marui used to offer an electric drill set and an electric grinding set for modeling purpose. The good thing about these products is that they will never be over powerful when working on your RC parts. The bad thing is that they require manual assembly prior to actual use :< To avoid over power destruction, […]

You may need to use nut drivers to set or remove hexheaded shaped screws, nuts and bolts. You may also need to use a pen shape soldering iron for rewiring the power connection. The Tamiya wheel wrench is my favorite (it is included in every Tamiya kit). It is compatible with the wheel nuts found […]
