How many degrees of servos are used in aircraft models? ——Comprehensive analysis of steering gear angle selection guide
Among model aircraft enthusiasts, the choice of steering gear has always been a hot topic. Recently, there has been a particularly heated discussion on the entire Internet about the angle of the steering gear of aircraft models. This article will combine the hot content of the past 10 days to provide you with a detailed analysis of the choice of aircraft model servo angle, and provide structured data for reference.
1. Basic concept of steering gear angle

The steering gear angle refers to the maximum range that the steering gear output shaft can rotate. Common steering gear angles are 90 degrees, 180 degrees and 360 degrees. Servos with different angles are suitable for different aircraft models and control requirements.
| Servo type | Angle range | Applicable scenarios |
|---|---|---|
| Standard steering gear | 90 degrees | Fixed wing aircraft, helicopter tail rudder |
| Large angle steering gear | 180 degrees | Aerobatics, multi-rotor drones |
| Continuously rotating servo | 360 degrees | Driven wheeled vehicles, special mechanical structures |
2. Key factors in selecting the steering gear angle of an aircraft model
When selecting the servo angle, the following factors need to be considered:
1.Aircraft type: Fixed-wing aircraft usually require 90-degree servos, while aerobatic aircraft may require 180-degree servos for a greater range of control.
2.control needs: Simple directional control only requires a 90-degree servo, while complex stunts may require a larger-angle servo.
3.flying style: Racing flight and aerobatic flight have different requirements for steering gear angle.
4.weight limit: Large-angle servos are usually larger in size and weight, and the load-bearing capacity of the aircraft model needs to be considered.
3. Recommended steering gear angles for popular aircraft models
According to recent sales data from aircraft model forums and e-commerce platforms, the following are the recommended servo angles for popular aircraft models:
| Aircraft model type | Recommended servo angle | Popular steering gear models |
|---|---|---|
| Entry level fixed wing | 90 degrees | SG90, MG90S |
| aerobatic fixed wing | 180 degrees | DS3218, MG995 |
| Large fixed wing | 90 degrees (high torque) | DS939MG, BMS-630DMH |
| FPV Drone | 180 degrees (PTZ) | EMAX ES08MA, TowerPro MG996R |
4. Steering gear angle setting skills
1.Remote control settings: Most modern remote controls allow the steering gear stroke to be adjusted and can flexibly control the actual steering gear rotation angle.
2.Mechanical adjustment: By changing the length of the servo arm or the position of the connecting rod, the actual deflection angle of the rudder surface can be adjusted.
3.Mixing settings: For aerobatic aircraft, dual servo mixing can be set to obtain a larger control range.
5. Summary of recent popular discussions
According to the discussions in the aircraft model community in the past 10 days, the following topics are the most popular:
1. The application of 180-degree servos in aerobatics is becoming more and more popular.
2. Difference in angle accuracy between digital servos and analog servos
3. How to improve flight stability through servo angle settings
4. Angle selection of micro servo in small scale model
6. Conclusion
The selection of the servo angle for an aircraft model requires comprehensive consideration of the aircraft type, flight requirements and budget. The 90-degree servo is suitable for most basic applications, while the 180-degree servo is more suitable for aerobatics and other scenarios that require a wide range of control. It is recommended that model aircraft enthusiasts should not only consider the angle range when choosing a steering gear, but also pay attention to parameters such as torque, speed and accuracy.
With the development of aircraft model technology and the continuous improvement of steering gear performance, more innovative angle designs may appear in the future. It is recommended to continue to pay attention to industry trends and choose the servo configuration that best suits your aircraft model.
