What It Is / How It Works
This servo horn arm is a metal steering part for RC cars and crawlers. The aluminum alloy arm attaches to a servo, so the servo can turn the steering linkage.
Who It's For / Use Cases
Servo horn arms suit RC hobbyists who are replacing the steering arm on a crawler or RC car and want a metal part over a plastic one. They also suit owners who keep a spare arm on hand for a build.
How to Use / Care
- Check that your servo output has a 25T spline before choosing this arm.
- Line up the arm with the servo spline so it sits square.
- Press the arm onto the spline and fasten it in place.
- Check that the arm turns freely before running the vehicle.
How to Choose
Check the servo spline count first, since this arm has a 25T spline. Choose the 20mm or 22mm size that suits the horn fit on your vehicle. Aluminum alloy suits owners who want a metal arm rather than plastic. The pack holds 2 pieces, so check whether one or two arms are needed for your build.
