SPIDER Automation | Silicone Anti-Vibration Motor Pad Set | Soft Mount Damping Gaskets for 22XX & 23XX Brushless Motors
The SPIDER Automation Silicone Anti-Vibration Motor Pad Set (Model: SIL-DAMP-22XX) is an essential acoustic and mechanical dampening accessory designed for FPV drone pilots, commercial UAV builders, and multi-rotor technicians. High-speed brushless motors operating at elevated RPMs inherently generate high-frequency kinetic vibrations caused by minor prop imbalance, motor bearing wear, or structural resonance. When motors are bolted directly to rigid carbon fiber frame arms, these vibrations travel unimpeded through the chassis into the flight controller’s onboard Gyroscope and Inertial Measurement Unit (IMU). This mechanical noise creates PID loop oscillations, hot motors, and flight instability. These precision silicone soft-mount pads isolate the motor base directly from the carbon fiber arm, effectively damping vibrations before they enter the airframe.
Precision die-cut from premium, high-density elastomeric silicone rubber, each pad features a 20 mm × 20 mm footprint with a 2 mm profile thickness. The silicone material is formulated with high internal loss properties, similar to industrial isolation bobbins used in professional aerial videography rigs. Supplied in a 4-pack set with a pre-applied self-adhesive backing, the pads adhere firmly to frame arms during motor installation, preventing motor bolt shearing and reducing frame chatter during aggressive acrobatic maneuvers.
Product Overview & Functional Design
The SIL-DAMP-22XX soft-mount gasket system addresses the core cause of gyro noise in modern high-performance FPV quadcopters. In Betaflight, EmuFlight, and INAV flight control firmware, software filters (such as D-term sliders and dynamic notch filters) are used to clean up noisy gyro signals. However, heavy software filtering introduces control latency and sluggish stick response.
By implementing physical mechanical soft-mounting at the motor mounting interface, motor noise is suppressed at the hardware level. This allows pilots to run cleaner flight controller filter settings, resulting in sharper stick response, cooler motor temperatures, and smoother FPV video feeds without high-frequency micro-jitter.
Technical Features & Functional Characteristics
- High-Damping Silicone Polymer: Engineered with high internal viscoelastic dampening properties to dissipate kinetic motor energy.
- Universal 22XX / 23XX Bolt Pattern: Pre-punched mounting holes align with standard M3 motor mounting screws on 2204, 2205, 2206, 2207, 2306, and 2307 motors.
- High-Tack Peel-and-Stick Adhesive: Integrated adhesive backing holds gaskets firmly in place on frame arms during motor alignment.
- Protective Arm & Motor Barrier: Eliminates direct metal-to-carbon contact, protecting carbon fiber arms from motor bell indentation and scratching.
- Stackable Thickness Tuning: 2mm base pads can be combined or placed above and below the carbon arm for total screw isolation.
- High Thermal Stability: Heat-resistant silicone withstands elevated motor operating temperatures without melting or deforming.
- Featherlight Airframe Mass (0.1g per pad): Minimal mass preserves strict takeoff weight limits (AUW) for maximum flight efficiency.
- PID Loop & Gyro Optimization: Reduces gyro noise floor, enabling lower D-term filtering and eliminating mid-throttle oscillation.
Mechanical Isolation Dynamics & Hardware Setup
The SIL-DAMP-22XX silicone pad acts as a mechanical low-pass filter positioned between the motor baseplate and the drone arm. Carbon fiber is an extremely rigid material that efficiently transmits high-frequency vibrations throughout the entire aircraft frame. Placing a 2mm silicone elastomeric layer between these rigid surfaces interrupts the acoustic transmission path, absorbing mechanical energy before it propagates into the central flight tower.
For complete mechanical isolation, builders can use the pads directly under the motor base and optionally place a secondary pad under the carbon arm beneath the screw heads. This ensures that the motor mounting bolts and motor housing are completely decoupled from the carbon fiber frame structure, providing full 360-degree vibration isolation.

Installation & Soft-Mounting Guidelines
Standard mechanical assembly practices should be followed when soft-mounting motors on drone frames.
- Frame Surface Cleaning: Clean carbon fiber motor arm ends thoroughly with isopropyl alcohol to remove dust and oil before applying the adhesive pads.
- Adhesive Application: Peel off the paper backing and press the silicone pad firmly onto the carbon arm, ensuring pre-punched bolt holes align with arm screw slots.
- Motor Alignment: Place the 22XX/23XX brushless motor onto the silicone pad and insert M3 motor screws carefully through the bottom of the arm.
- Screw Torque Management: Tighten motor screws evenly in a cross pattern. Do not over-tighten to the point of completely flattening the silicone pad; allow the rubber to retain slight elasticity for optimal vibration damping.
- Threadlocker Caution: If using blue threadlocker (Loctite) on motor screws, apply it sparingly to the screw threads and avoid spilling liquid threadlocker directly onto the silicone rubber material.
