What does AT9S remote control rudder measurement mean?
In the field of model aircraft and drones, remote control settings and parameter understanding are crucial to the flight experience. As a popular remote control, AT9S's "rudder volume" parameter is one of the key functions that users often need to adjust. This article will explain in detail the meaning, function and how to set the helm of the AT9S remote control, and combine it with the hot topics and hot content on the Internet in the past 10 days to help players better master this function.
1. Definition of AT9S remote control rudder quantity

Travel Volume refers to the signal range output by the remote control, usually expressed as a percentage. It determines the maximum signal amplitude received by the servo or ESC, and directly affects the rotation angle of the servo or the output power of the ESC. Simply put, the greater the steering amount, the greater the rotation range of the steering gear or the speed range of the motor.
2. The role of rudder quantity
1.Control the steering gear rotation range: Rudder amount determines the maximum rotation angle of the servo. For example, when the rudder amount is set to 100%, the servo can rotate to the maximum angle; when set to 50%, the rotation range is halved.
2.Adjust motor output: For motors controlled by ESC, the steering amount determines the maximum speed of the motor. The greater the rudder amount, the higher the motor speed.
3.Avoid mechanical interference: By adjusting the steering amount, you can prevent the steering gear from rotating too much, causing collision or damage to mechanical parts.
3. How to set the steering volume of AT9S remote control
The rudder setting of the AT9S remote control is usually completed through the "Travel Adjust" or "End Point" option in the menu. Here are the specific steps:
| steps | Operation |
|---|---|
| 1 | Enter the remote control menu and select the "Travel Adjust" or "End Point" option. |
| 2 | Select the channel that needs to be adjusted (such as aileron, elevator, throttle, etc.). |
| 3 | Adjust the rudder percentage in the positive (+) and negative (-) directions respectively. |
| 4 | Save the settings and test the response range of the servo or motor. |
4. Hot topics and content on the entire network in the past 10 days

5. Frequently Asked Questions
1.What are the effects of setting the rudder amount too large or too small?
If the rudder amount is set too high, the servo or motor will be overloaded, which may damage the equipment; if it is set too small, the control range will be insufficient and flight performance will be affected.
2.How to determine the appropriate rudder value?
It is recommended to start testing with a small amount of rudder, gradually increase it, and observe the response of the servo or motor until the ideal range is reached.
3.What is the difference between rudder volume and D/R (rudder ratio)?
Rudder quantity is the signal output range, and D/R is the signal sensitivity. The two can be used together, but have different functions.
6. Summary
The rudder setting of the AT9S remote control is an important part of flight control. Proper adjustment of the rudder can optimize flight performance and protect the equipment. Through the introduction of this article and the reference of hot topics across the Internet, I hope players can better understand and apply this function.
