What does the aircraft model steering gear g mean? Analysis and hot topic summary
The aircraft model steering gear is one of the core components of remote control models (such as drones, fixed-wing aircraft, car models, etc.) and is responsible for controlling direction, throttle or other mechanical actions. The "g" in "server g" usually refers to the torque unit of the servo (kg·cm or g·cm), and may also be related to the model naming. This article will combine the hot topics on the Internet in the past 10 days, analyze the steering gear parameters in detail, and attach a summary of hot topics.
1. Servo parameter analysis: What is "g"?
The "g" of the steering gear usually has the following two meanings:
| Terminology | meaning | Example |
|---|---|---|
| Torque unit (g·cm) | Indicates the ability of the servo to output torque. For example, "9g servo" means the torque is 9g·cm | 3.7g servo, 20kg servo |
| Model identification | Some manufacturers use "g" as the model suffix, such as SG90, MG996R | Fraser 9g servo |
2. Hot topics on aircraft models and steering gears in the past 10 days on the entire network
The following are recent hot discussions in the aircraft model circle, covering technology, new products and industry trends:
| Topic classification | Hot content | heat index |
|---|---|---|
| Technical discussion | “Digital servos vs analog servos: how to choose?” | ★★★★ |
| New product release | "XX brand launches ultra-thin waterproof servo with torque up to 25kg·cm" | ★★★☆ |
| Industry news | “The price of aircraft model parts has increased, and the supply of servos is in short supply.” | ★★★ |
| User case | "DIY Model Aircraft Servo Modification Tutorial" | ★★★★☆ |
3. How to choose a suitable steering gear?
When selecting a servo, you need to pay attention to the following parameters:
| parameters | Description | Recommended value |
|---|---|---|
| Torque (g·cm/kg·cm) | Choose based on model size and load requirements | Small UAV: 3-9g·cm |
| Rotation speed (seconds/60°) | Affects response speed, racing models require high-speed servos | 0.1-0.3 seconds/60° |
| voltage range | Commonly used is 4.8V-7.4V, the high-voltage steering gear has stronger performance | 6V-7.4V |
4. Recommended recent popular steering gear models
According to forum and e-commerce platform data, the following models have received relatively high attention recently:
| Model | Torque | Features |
|---|---|---|
| SG90 | 1.8kg·cm | Affordable and suitable for entry-level |
| MG995 | 13kg·cm | Metal gears, strong durability |
| DS3225 | 25kg·cm | High-voltage digital steering gear, precise control |
5. Summary
The key to "servo g" is to understand its torque unit or model identification. Recently, the hot spots in the aircraft model circle have focused on technology comparison, new product performance and DIY modification. When choosing a servo, you need to consider parameters such as torque, speed, and voltage, and also refer to the cost-effectiveness of popular models. With the development of technology, high-voltage digital servos may become a future trend.
