What is the drone servo stroke?
The UAV servo stroke is an important parameter in the UAV flight control system, which directly affects the control performance and stability of the UAV. This article will introduce in detail the definition, function, adjustment method and related hot topics of the drone servo stroke.
1. Definition of UAV steering gear stroke
The drone servo stroke refers to the rotation angle or displacement range of the servo output shaft from the minimum position to the maximum position. Usually expressed as an angle (such as ±60°) or a percentage (such as 100%). The steering gear stroke determines the maximum deflection amplitude of the UAV control surface, which in turn affects the flight attitude and response speed.
| parameters | Description | Typical value |
|---|---|---|
| Stroke angle | Steering gear output shaft rotation range | ±60° |
| Travel percentage | The stroke ratio corresponding to the remote control signal | 100% |
| physical limitations | Maximum allowable stroke of mechanical structure | ±70° |
2. The function of steering gear stroke
1.Control sensitivity:The greater the stroke, the greater the deflection amplitude of the control surface, and the more sensitive the response of the drone is.
2.Flight stability:Proper travel settings can avoid instability caused by excessive control.
3.Energy efficiency:A reasonable stroke can reduce the load on the steering gear and extend the battery life.
| Itinerary settings | Impact on flight |
|---|---|
| Too big | Responsive but prone to instability |
| too small | Sluggish controls |
| Moderate | Balance sensitivity and stability |
3. How to adjust the steering gear stroke
1.Remote control settings:Servo stroke adjustment function through the remote control (EPA/End Point Adjustment).
2.Flight control software:Use flight control parameter adjustment software (such as Betaflight, INAV) to set the digital servo stroke.
3.Mechanical limit:Check whether the physical limits of the servo rocker arm and connecting rod are reasonable.
| Adjustment method | Applicable scenarios |
|---|---|
| Remote control EPA | Traditional PWM servo |
| Flight control software | Digital servo/flight control integration |
| Mechanical adjustment | all types |
4. Recent hot spots related to drones

5. Frequently Asked Questions
Q: Is the larger the servo stroke, the better?
A: No. It needs to be considered comprehensively based on the type, weight and flight requirements of the drone.
Q: How to judge whether the itinerary is suitable?
A: You can observe through test flight: 1) control response speed; 2) flight stability; 3) steering gear heating.
Q: What is the difference between the travel settings of digital servos and analog servos?
A: Digital servos are usually set through the flight control software and have higher accuracy; analog servos are mainly adjusted through the remote control EPA.
Summary:The UAV servo stroke is a key parameter that affects flight performance and needs to be set appropriately according to actual needs. With the development of drone technology, the steering gear control system is becoming increasingly intelligent, providing more precise control for flight.
