5. Setup
5.1 Mounting the Servo
- Identify the designated servo mounting location on your RC vehicle or project.
- Use the provided mounting screws and grommets to secure the servo firmly. Ensure the servo is aligned correctly and does not interfere with other components.
- The low-profile design is particularly beneficial for vehicles with limited space, such as 1/10 and 1/12 scale RC drift cars.

5.2 Wiring Connection
- Connect the servo's three-wire cable to the appropriate channel on your RC receiver or flight controller. The standard color code is:
- Brown: Negative Pole (Ground)
- Red: Positive Pole (Power)
- Orange: Signal
- Ensure the polarity is correct to prevent damage to the servo or receiver.
5.3 Attaching the Servo Horn
- Before attaching the servo horn, ensure your RC system (transmitter and receiver) is powered on and the servo is centered. This can typically be done by setting the trim on your transmitter to neutral.
- Select the appropriate servo horn for your application. The included 25T metal servo arm offers enhanced durability.
- Carefully press the servo horn onto the servo output shaft. Ensure it is aligned as straight as possible relative to your steering linkage or control surface.
- Secure the servo horn with the small screw provided, typically inserted through the center of the horn into the servo shaft.
6. Operating Instructions
6.1 Initial Power-Up and Testing
- With the servo properly mounted and connected, power on your RC transmitter first, then the receiver/ESC.
- Gently move the corresponding control stick on your transmitter to observe the servo's movement. The servo should respond smoothly and precisely to your inputs.
- Verify that the servo's travel limits (endpoints) are correctly set within your RC system to prevent over-stressing the servo or mechanical linkages. The servo supports a PWM signal range of 500µsec to 2500µsec for a 180° travel.

7. Maintenance
7.1 Cleaning
- Regularly clean the exterior of the servo to remove dirt, dust, and debris. Use a soft, dry cloth.
- For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the servo casing, despite its IP66 rating.
- Avoid using harsh chemicals or solvents, as these can damage the plastic casing or internal components.
7.2 Inspection
- Periodically inspect the servo gears for wear or damage. While the metal gears are durable, extreme impacts can cause issues.
- Check the servo wire for any cuts, fraying, or loose connections.
- Ensure the servo horn is securely attached and not stripped.
7.3 Storage
- Store the servo in a cool, dry place away from direct sunlight and extreme temperatures.
- Keep it protected from dust and moisture when not in use.
8. Troubleshooting
8.1 Servo Not Responding
- Check Power: Ensure the receiver and servo are receiving adequate power. Verify battery levels.
- Check Connections: Confirm all wiring connections between the servo, receiver, and power source are secure and correctly polarized.
- Transmitter/Receiver Link: Ensure your transmitter and receiver are properly bound and communicating.
- Test with Another Channel/Servo: Try connecting the servo to a different channel on your receiver, or test a known working servo on the same channel to isolate the issue.
8.2 Erratic or Inconsistent Movement
- Interference: Check for sources of electrical interference near your RC system.
- Power Supply: An unstable or insufficient power supply can cause erratic behavior. Ensure your battery and BEC (Battery Eliminator Circuit) are functioning correctly.
- Damaged Gears: Inspect the servo gears for any signs of stripping or damage.
- Linkage Binding: Ensure the mechanical linkages connected to the servo arm move freely and are not binding.
8.3 Excessive Noise During Operation
- Gear Wear: Increased noise can indicate wear on the internal gears. Inspect and replace if necessary.
- Overload: The servo might be under excessive load. Reduce the load or ensure the servo is appropriately sized for the application.
- Binding: Check for any mechanical binding in the linkages that could be straining the servo.
