Frequently Asked Questions (FAQs)

1. Do servos come with horns?

Servos often come with several wheels or levers, known as "horns", than can be attached to the shaft, to fit the device they are operating.

2. Are all RC servos the same size?

Most hobby servos will be classified by their size. Different manufacturers might have small variances in how they list their servo sizes but they can usually be boiled down to three types: micro, standard and giant.

3. How do I extend my servo arms?

Measure the length you want , cut off, Drill holes in each end for your Z bend and one larger hole in center for the servo screw. Adjust your servo to neutral or center position and screw it together.

4. What size servo do I need?

It is important to choose a servo which is strong enough to handle the size and weight of your car. A normal 1/10 buggy or short course/stadium truck ideally needs a torque of around 10kg. A 1/10 on-road car will be alright with a little less, so around 8kg will be enough.
