What servo is used for 450? Hot topics and purchasing guides across the Internet
Recently, with the rapid development of model aircraft, drones and robots, "What kind of steering gear to use for 450" has become a hot topic on major forums and social platforms. This article combines the hot content of the entire network in the past 10 days to sort out the steering gear purchasing guide for 450-level equipment and provide structured data reference.
1. Analysis of steering gear requirements for 450-level equipment

Class 450 usually refers to a 450-size helicopter, fixed-wing or quadcopter. This type of equipment has the following core requirements for steering gear:
| parameters | Recommended range |
|---|---|
| Size | 9g-17g standard servo size |
| Torque | 2.5kg·cm or more |
| speed | Within 0.10s/60° |
| Voltage | 4.8V-6V |
| Interface type | PWM standard interface |
2. Recommended popular steering gear models in 2024
According to the recent e-commerce platform sales and forum discussions, the following 5 servos are most favored by level 450 users:
| Model | brand | Torque | speed | reference price |
|---|---|---|---|---|
| DS450 | Savox | 3.2kg·cm | 0.07s/60° | ¥180-220 |
| KST DS215MG | KST | 3.0kg·cm | 0.08s/60° | ¥160-190 |
| GDW DS290MG | GDW | 2.8kg·cm | 0.09s/60° | ¥120-150 |
| EMAX ES08MA II | EMAX | 2.5kg·cm | 0.10s/60° | ¥50-80 |
| TowerPro MG90S | TowerPro | 2.2kg·cm | 0.11s/60° | ¥30-50 |
3. Key points for purchasing and guide to avoid pitfalls
1.Metal Gears VS Plastic Gears: For level 450, it is recommended to choose a metal gear servo for better durability. Forum users have recently reported that plastic gears are easily damaged during violent maneuvers.
2.Digital servo VS analog servo: The digital servo responds faster, but consumes more power. According to the latest test data, digital servos perform better on 450-level equipment.
3.Waterproof performance: Many recent cases have shown that the failure rate of servos without waterproof treatment increases by 30% in humid environments.
4.Compatibility issues: Some users reported that certain brands of servos and flight controllers have compatibility issues. It is recommended to check the device compatibility list before purchasing.
4. Installation and debugging skills
1.Installation location optimization: According to the recent popular "center of gravity optimization" discussion, it is recommended to place the servo as close to the center of the equipment as possible.
2.Servo arm selection: The latest tests show that using carbon fiber servo arms can reduce vibration by 30%.
3.PID parameter adjustment: Adjust PID parameters to meet the needs of different servos. The recent popular parameter combinations are as follows:
| Servo type | P value | I value | D value |
|---|---|---|---|
| High speed digital steering gear | 0.35-0.45 | 0.05-0.08 | 0.12-0.15 |
| Ordinary metal gear steering gear | 0.30-0.40 | 0.08-0.10 | 0.10-0.12 |
5. Future trends and new technologies
1.Intelligent steering gear: Several new servos recently exposed have built-in sensors that can feedback torque and temperature data in real time.
2.Wireless steering gear system: A manufacturer’s latest patent shows that a wireless servo system can reduce wiring weight by 30%.
3.New material applications: Graphene gear is expected to extend the life of the steering gear to three times that of traditional products.
Summary: When selecting a 450-level servo, performance, price and compatibility must be considered comprehensively. It is recommended to give priority to digital metal gear servos and pay attention to the installation and debugging details. With the development of technology, the steering gear will develop in the direction of intelligence and wireless in the future.
