This mini servo is quite impressive, it does quite the job for a large range of tasks. Only weights 9 grams and gives you a 1.6kg cm torque. Pretty strong regarding its size. Suitable for Beam robots and other automation tasks.

360 degrees
The end points of the servo can vary and many servos only turn through about 170 degrees. You can also buy ‘continuous’ servos that can rotate through the full 360 degrees.

Some servos come with metal gears, which are more rugged, but they may emit a bit more noise. The gearbox means a servo is strong, and somewhat slow. It can only move back and forth about 180 degrees. The movement might be more limited on certain servos, perhaps 170 degrees on some, only 90 degrees on another.

If you purchase a servo for a model known to use a 9g servo, you know the hole you have to build for it to fit. If you purchase a 5g servo, it will be a different hole and you may have a 6 or 7 gram weight, but the servo fits as it should.

Different types and sizes of cars are designed for different size servos, which means that the first thing to take into account is the servo mounting dimensions of your car. The most common size of servo is the “Standard” size. A standard size servo is roughly around 40 mm (length) x 38mm (height) x 20mm (width).

In our testing these servos can lift about 3.75lbs that is positioned on an arm 1cm out from the shaft , so they are actually fairly strong little motors.

A Servo Motor does not normally spin a full 360 degree rotation. Instead it is limited to a range of 180, 270 or 90 degrees depending on the make or type. A control signal is sent to the servo to position the shaft at the desired angle.

90° – 180°
The physical limits and timings of the servo hardware varies between brands and models, but a general servo’s full angular motion will travel somewhere in the range of 90° – 180° and the neutral position (45° or 90°) is almost always at 1.5 ms.

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.

Top three factors in choosing a servo motor

1. Continuous torque.
2. Peak torque.
3. Speed.
4. Gear ratio.
5. Inertia.
6. Accuracy.
7. Environment factors.
8. Efficiency.

Suitable for Beam robots and other automation tasks. Keep in mind that if you need some heavy lifting you should be considering some of our other options. This servo is for you if you are planning on building smaller size robots. Project 1. Micro:bit Surprise box
