What degree of steering gear does the aircraft model use? ——Analysis of popular model aircraft accessories
Recently, one of the hot topics discussed by aircraft model enthusiasts on major forums and social media is the choice of steering gear, especially the rotation angle of the steering gear. This article will combine the popular discussions on the Internet in the past 10 days to provide you with a detailed analysis of the steering gear angles commonly used in aircraft models, and provide structured data for reference.
1. Basic concept of steering gear rotation angle
The rotation angle of the servo refers to the maximum range that the servo output shaft can rotate, usually expressed in degrees. Common steering gear angles are 90 degrees, 180 degrees and 360 degrees. Different angles of steering gear are suitable for different aircraft model scenarios.
| Servo type | rotation angle | Applicable scenarios |
|---|---|---|
| Standard steering gear | 90 degrees | Fixed wing aircraft, car model steering |
| Large angle steering gear | 180 degrees | Robot joints, multi-rotor drones |
| Continuously rotating servo | 360 degrees | Wheel drive, special mechanical structure |
2. Comparison of popular model aircraft steering gear models and angles
According to the recent discussion, the following are several popular aircraft model servos and their angle parameters:
| Brand | Model | rotation angle | Torque (kg·cm) | Price range (yuan) |
|---|---|---|---|---|
| Futaba | S3003 | 90 degrees | 3.2 | 80-120 |
| Savox | SC-1258TG | 180 degrees | 12.5 | 400-500 |
| TowerPro | MG995 | 120 degrees | 13 | 50-80 |
| Hitec | HS-422 | 90 degrees | 4.1 | 100-150 |
3. How to choose the appropriate steering gear angle?
When selecting the servo angle, the following factors need to be considered:
1.Model aircraft type: Fixed-wing aircraft usually use 90-degree servos, while robots or multi-rotor drones may require 180-degree servos.
2.control needs: If precise control is required (such as rudder), a 90-degree servo is more suitable; if a wide range of movement is required (such as a robotic arm), a 180-degree servo is better.
3.budget: Large-angle servos are usually more expensive and need to be weighed according to the budget.
4. Recent hot topics: Modification and upgrade of steering gear angle
Recently, many model aircraft enthusiasts have discussed how to extend the steering gear angle through modification. For example, a 90-degree servo can be changed to 180 degrees by adjusting the servo potentiometer or using an external controller. However, this modification requires a certain technical foundation and may affect the life of the steering gear.
5. Summary
The rotation angle of the steering gear is one of the key parameters of the performance of the aircraft model. The 90-degree servo is suitable for most basic applications, while the 180-degree servo is suitable for scenes that require a larger range of motion. Recently popular steering gear models such as Futaba S3003 and Savox SC-1258TG represent typical products from different angles. The type of aircraft model, control requirements and budget need to be comprehensively considered when selecting.
I hope the structured data and analysis in this article can help you make a better choice of steering gear. If you have more questions, please join the discussion!
