Things to Consider Before Choosing Servo

By now you should have a clear understanding of servos for 1/10 4WD buggies. But if you are still confused, don’t worry. 

Because down here we have everything to clear your confusion. Here we have discussed all the parts of a servo. 


The gear is the most crucial component of the servo. because they are moved by the gear, which catches on to the wheel. The servo will be useless without good gear. Therefore, the better the gear, the better the servo. 

Plastic or metal can be used to create the equipment. But having metal gear that cannot be stripped is preferable. because a plastic gear may eventually wear out, rendering the servo useless.


Your RC’s performance may be affected by the servo’s torque. The torque figures show how much pressure can be applied to the wheels. 

RCs can weigh a lot. Additionally, steering the RC can be challenging due to wheel friction. Because of this, the servo will function better for the RC the higher the torque figure. However, a torque of at least 10 kg/cm will be sufficient in most cases.


Additionally to torque, speed is important. Because the RC can steer faster or slower depending on the speed. 

The servo’s speed may be more significant than its torque value. Because if the servo’s speed is low, what are you going to do with all that torque? Therefore, you require the servo to be responsive while using all of its torque. 

Being typically 0.15 seconds is a fantastic number.

Bearing Type

The smoothness can vary depending on the type and quantity of bearings. Under the servo’s gears, there are balls. which moves when you move your RC’s steering. 

It is better to have several bearings. Because the servo’s performance may suffer if there is only one bearing. The type of bearing is important as well. You can have better frictionless maneuverability with precision ball bearings made by CNC machines.

Frequently Asked Questions (FAQs)

How to Attach a Servo to the RC?

Channel one should receive the servo plug. Once the RC is running, connect the servo horn to the servo. Make sure the servo horn’s screw is tightened. After flipping the RC over, secure the servo with the screws. Make sure the RC wheels are connected to the servo horn.

What can be used as Servo Grease?
