May 19, 2011 · At the minimum you should be looking for about 130 oz/in of torque and 0.15 sec response time regardless of brand. LOL...that might be confused with a fancy, high priced brand-name servo from like 10 years ago. .15 second transit time is not consistent with fancy, high priced anything.
Apr 07, 2022 · 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.

Size - The servo mounting dimensions will determine the size of the servo that you choose. Our servos are classified as Large Scale, Standard, Mini, or Micro, to help narrow your choices. Also note that some have different depths, which can cause issues in models with limited mounting space. Torque - What is the size a
All of them are high torque servos, ranging from 11 Nm to 216 Nm (with the peak torque from 28 Nm to 333 Nm accordingly).
In general, the bigger and heavier the model, the higher torque your servo should provide. Airplane control surface area and servo arm length are also factors. Speed - A fast or slow servo will alter the 'feel' of your model. Fast is good, but using a servo that is too fast can cause a twitchy feel.
400 ounce-inchesThe servo utilizes full metal gears, dual ball bearings, and an aluminum center section for added heat dissipation. A cutting edge brushless motor provides 400 ounce-inches of torque for extreme applications.
A possible remedy to get a servo motor with high torque is to add a gearhead—an arrangement of gears ensuring proportional speed-to-torque conversion. The gear ratio is the measure to which the device amplifies rotational force, while decreasing revolution rates.

Therefore, the total torque requirement for a servo is:Torque Required By a Servo Motor = (Torque Due to Force of Gravity on Links and Payload) + (Torque Due to Angular Acceleration of Links and Payload)τ = Iατ = Iατ = 1.414 kg-m2/s2 = 1.414 Nm = 14.410 kg-cm = 200 oz-in.More items...•Oct 11, 2020
Traxxas new High-Torque servos combine maximum steering authority with a long list of high performance features. Both servos utilize steel gears, dual ball bearings, and an aluminum center section for added heat dissipation.
This is the Traxxas 2075 Digital High-Torque Waterproof Servo. This servo puts out 125 oz/in of torque at 6V.
This is true for all Traxxas receivers; it's the waterproof box that encloses the receiver that allows it to be used in water, mud and snow. The transmitter is not waterproof, so use caution when operating your model in wet conditions, and do not operate your model in the rain.

The top-of-the-range alpha3000HVis is the world's largest synchronous servo motor with a maximum torque of 5500Nm and a stall torque of 3000Nm. The maximum and rated power outputs are 440kW and 220kW respectively, with a maximum continuous speed of 2000rpm.Jul 23, 2003
Servo motors or “servos”, as they are known, are electronic devices and rotary or linear actuators that rotate and push parts of a machine with precision. Servos are mainly used on angular or linear position and for specific velocity, and acceleration.
Stall torque is the torque load that causes a servo motor to “stall” or stop rotating. A stall torque of 35 kg-cm means that the servo motor will stop rotating when it is trying to move ...
The official metric (SI) units of torque is the Newton-meter (Nm). However in datasheets for servo motors, you’ll often see ounce-force-inch (oz-in) or kilogram-force centimeter (kg-cm). In the real world, a servo motor’s axis is the blue nail. This is the robotic arm’s joint. The orange bar is the link of a robotic arm.
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. Heavy 4WD trucks need 15kg and upwards, ...
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). These are used on lots of 1/10 and 1/8 vehicles. A sub-division of standard sized servos are the special “Low-Profile” servos, which is the same length and width as a standard servo, ...
Going to off-road cars, a good 1/10 buggy servo should definitely have a speed of under 0,15s. The heavier the car is, the slower it will be in reaction, so you don’t need the most superfast servos, but the speed should be 0,2s or below for any type of car.
Servos play a very important part in any RC car, with the servo is responsible for steering the car, and on a nitro cars, a second servo also controls throttle and braking action. As with any component, there are different specifications of servos available. So let’s take a look at what we need to consider when choosing a servo.
A servo that is fast enough for the type of car is equally important, as a too slow servo will kill the steering feel. The smaller/lighter and faster your car is, the more important it is with a fast servo. On on-road cars you want a servo to be 0,1s or faster, to ensure you have the response needed for these cars.
Below the standard size servos, there are “Mini”, “Micro”, and even super-small “Sub-Micro” sized servos, which are common on smaller 1/12 and 1/16 size vehicles. Above the standard size servos you find “Large Scale” or “XL” servos, which are much bigger in dimensions, and used for many large scale vehicles in 1/5 and 1/6 sizes.
Aluminium is used to improve heat dissipation, but this obviously adds a bit of weight over a plastic case. A full aluminium servo case eliminates flex for a more stable gear train and servo mounting points, which can be useful especially for heavier vehicles.
Speed - A fast or slow servo will alter the 'feel' of your model. Fast is good, but using a servo that is too fast can cause a twitchy feel. Don't overdo it! Voltage - All of our servos can be run on 6 volts.
Servo Case - Aluminium is used to improve heat dissipation from the motor but this has a slightly higher weight over the plastic case models. A full aluminium case reduces flex, and provides a more stable platform for the gear trains and mounting points for heavier models.
If weight or price is a concern, then plastic gears are a good choice for "low impact" applications. If you aren't sure, choose metal gears. We recommend using a servo saver for any high impact application, regardless of gear material choice. Motor - Savox offers three motor choices: DC, Coreless, and Brushless.
These servos can also be used with lower voltages but the performance will be lower. Gear Train - Metal gears are recommended for cars and trucks, or any model that will be used aggressively or will be subject to hard impacts.
Full aluminum case servos are NOT indestructible, but are quite strong. Waterproof - Our waterproof servos are IP67 rated, which means they are "Protected against the effects of immersion in water to depths between 15 cm and 1 meter".
