RC vehicle differentials are an essential component of any RC car or truck. They allow the wheels to rotate at different speeds, which is necessary for turning and maintaining traction on uneven surfaces. There are several types of differentials available, including open, limited slip, and spool differentials. Open differentials are the most common and allow for smooth turning, while limited slip differentials provide more traction and control. Spool differentials are the most aggressive and provide maximum power transfer to the wheels. Choosing the right differential for your RC vehicle can greatly improve its performance and handling on the track or off-road.

Frequently Asked Questions (FAQs)

1. What are differentials on an RC car?

Differentials on an RC car allow the wheels on the left and right side of the car to spin at different speeds. They play a crucial role in the car's performance and handling.

2. Does an RC car need a differential?

Yes, an RC car typically needs a differential. Many RC cars use oil-filled differentials, and it is important to regularly rebuild and maintain them. Adjusting the differential action by changing oil viscosity can also provide performance benefits.

3. What are the 4 types of differentials?

The four common types of differentials in the market are open differentials, locking differentials, limited-slip differentials, and torque-vectoring differentials.

4. How do I know what differential I need?

Differentials can be visually identified by the number of cover bolts, the shape of the cover, the number of ring gear bolts, and the ring gear diameter. They can also be categorized based on whether the center section is an integral or dropout design.

5. What is the difference between a ball diff and a gear diff?

A ball differential is a type of differential commonly used in RC cars. It uses small ball bearings rotating between two plates instead of bevel gears, which is the case in a gear differential.

6. What happens if you don't have a differential?

If an RC car doesn't have a differential, both wheels on the axle would rotate at the same speed. This would cause the car to tend to go in a straight line and can result in poor handling, especially during turns.

7. Why do we weld differentials?

Welding a differential involves keeping both back wheels of the car spinning at the same speed. This can cause the inner wheel to lose traction and skip, resulting in easier oversteer. Welding differentials is often done for specific driving techniques or purposes.
