Mounting servos is a fundamental part of the RC hobby. We have a few tips to help you with this task.
1. If the servo comes with rubber isolators, use them.
2. Insert the brass grommets into the isolators from the bottom, so that the flange of the grommet is between the isolator and the model's mounting surface.
3. Set the servo into position on the model. Mark the locations of the mounting holes using a mechanical pencil with the lead extended.
4. Drill holes into the servo tray using a pin vise and a drill bit that is slightly smaller than the diameter of the mounting screws.
5. Consider using Du-Bro Socket Head Mounting Screws (part 893) with a Du-Bro 6/64" ball driver (part 442).
6. Insert and remove a servo mounting screw into each of the drilled holes.
7. Apply thin CA to the mounting holes. This will harden the wood around the holes.
8. Set the servo into position and secure with servo mounting screws.
9. Servo installation is complete! See DuBro.com for servo horns and other control system products.
DU-BRO 101: How to Properly Mount Servos for RC Airplanes
Properly mounting servos is one of the most important steps in building or repairing an RC airplane. In the DU-BRO 101 video “How to Mount Servos,” hobbyists learn the correct way to install servos for strong, smooth, and reliable control response. Whether you’re a first-time builder or an experienced flyer, mastering the basics of servo installation ensures your aircraft performs safely and consistently in the air.
Before getting started, make sure you have the correct tools and hardware. You can find servo-related parts and accessories in our Radio Accessories Collection and essential mounting hardware in our Hardware Kits.
⭐ Why Proper Servo Mounting Matters
Correct servo installation directly affects how your control surfaces respond. Poorly mounted servos can cause:
-
Excessive vibration
-
Inconsistent control inputs
-
Binding or slop in linkages
-
Servo failure during flight
A secure, well-aligned servo mount ensures smoother flying and more precise maneuverability. For complete linkage components, see our Control Hook-Ups Collection.
🛠️ What the Video Teaches You
The DU-BRO video walks you through the full process of installing servos into an RC aircraft, including:
-
Choosing the correct servo screws
-
Marking and aligning servo rails
-
Using vibration-reducing grommets
-
Correctly tightening servo screws
-
Ensuring linkage geometry is straight and efficient

🔧 Step-by-Step Highlights from the Video
1. Prep the Servo Tray or Rails
Clean the mounting area and ensure the rails or tray are smooth, straight, and properly spaced.
2. Install Rubber Grommets
These help reduce vibration and protect the servo from shock during abrupt maneuvers or rough landings.
3. Insert Brass Eyelets Correctly
Eyelets should be installed from the bottom to provide proper cushioning and alignment.
4. Align the Servo Perfectly
Make sure the output shaft faces the correct direction and that the servo sits square in the mount.
5. Tighten Screws Evenly
Avoid overtightening—this can crush the grommets and remove vibration protection.
