- Function and stability: The guiding star ring contacts the base to prevent the aircraft from rubbing against the base during glide and vibration, resulting in a more stable connection. - Protection against scratches: Three set screws with protective heads guard against scratches. For mounting, use thicker M6 screws or set screws with protective heads to avoid marring the surface. - Durable construction: Metal construction with a thickened collar enhances rigidity and long-term durability. - Wear resistance and fit: The width of the play loop is extended by 14 mm, increasing the contact area for greater stability, and the thickened ring is less prone to deformation. - Compatibility and mounting: Designed to work with standard fasteners and hardware used in typical assembly setups requiring a secure, low-scratch connection. Applications and use scenarios: - RC model aircraft assembly: Use in flight control or mounting assemblies where a stable contact to the base is critical to minimize movement and wear during glide and shake tests. - Drone or UAV test benches: Employ in test rigs where repeatable, stable contact with the base reduces play and wear during vibration and maneuver simulations. - Mechanical rig or alignment fixtures: Ideal for setups requiring a robust, scratch-resistant interface with a reinforced collar and expanded slack loop to improve alignment and durability over time.
