Best Rc Servo Horns Buying Guide
Before choosing the best rc servo horns you should consider following options:
1. Material: The most common materials used for these attachments are nylon and aluminum. Generally, aluminum is preferred for its durability, but these horns are also heavier.
If you are looking for something lightweight, then you can opt for nylon. However, it is important to note that nylon horns are not suitable for heavy-duty applications.
2. Mounting Style: These attachments can be mounted in two different ways – with mounting holes or without mounting holes.
If you need to attach the horns to something that has holes, then a horn with mounting holes is your best bet.
However, if you want to attach the horns to something that doesn’t have any holes, then you should opt for a horn without mounting holes.
3. Length and Diameter: The length and diameter of the horn plays an important role in determining its strength and load capacity.
The longer the horn, the higher the loading capacity. However, longer horns also make the mechanism more complicated.
The diameter of the horn also determines its strength. The wider the horn, the higher the strength. However, wider horns also make the mechanism bulkier.
4. Angle: Depending on the application, you may require a horn with a certain angle to operate. For example, if you want to use the horn to actuate a valve, then you will require a different angle than what you would want to use it for a linkage.
Depending on the application, you can decide the angle of the horn, but make sure that the angle is within the limit of the mechanism.
5. Pivot Distance: The pivot distance defines the required length of the linkage that the horn needs to actuate. The longer the pivot distance, the easier it will be for the mechanism to operate.
Generally, a shorter pivot distance is preferred for heavy-duty applications because it makes the mechanism easy to operate.
6. Torque Rating: The torque rating of the horn determines its maximum strength. The higher the torque rating, the stronger the horn will be. However, you will also have to consider the length of the linkage that the horn will actuate.
The longer the linkage, the higher the torque that can be applied to the mechanism.
7. Cost: The cost of the attachment depends on various factors, including the materials used, the length and diameter, the mounting style, and the angle.
What else you should know about rc servo horns
