RC Plane Links And Connectors

RC plane links and connectors are essential components that allow for the mechanical linkage between control surfaces, servos, pushrods, and other moving parts of the aircraft. They play a critical role in transmitting control inputs from the servo to the control surface, enabling precise and responsive flight maneuvers. Here's a detailed overview:

1. Types of Links and Connectors:

• Clevises: Clevises are small metal or plastic connectors that attach pushrods to control horns or servo arms. They feature a threaded pin that can be adjusted for length to fine-tune control surface alignment and throw.

• Ball Links: Ball links consist of a ball joint connected to a threaded rod or shaft. They provide a wide range of motion and allow for smooth and precise control surface movement.

• Turnbuckles: Turnbuckles are adjustable connectors that consist of two threaded rods with opposite-hand threads. They allow for precise adjustment of pushrod length to achieve proper control surface alignment and throw.

• Z-Bends: Z-bends are simple bends in pushrods or control rods that allow for attachment to control horns or servo arms. They are a common and easy-to-use method for connecting pushrods to control surfaces.

• Dubro or Sullivan Style Connectors: These connectors feature a unique design with metal or plastic components that allow for secure attachment and adjustment of pushrods to control surfaces or servo arms.

2. Components of Links and Connectors:

• Rod or Shaft: The main component of links and connectors, usually made of metal, plastic, or composite materials. It serves as the structural element that transmits motion from the servo to the control surface.

• Connector or Joint: The connecting element that attaches the rod or shaft to the control surface, servo arm, or other moving part of the aircraft. It may feature threads, ball joints, or other mechanisms for adjustment and attachment.

• Locking Mechanism: Some links and connectors feature a locking mechanism, such as a set screw or locking nut, to secure the connection and prevent unintentional disconnection during flight.

3. Installation Tips:

• Ensure proper alignment and fitment of links and connectors to prevent binding or interference with control surface movement.

• Use appropriate tools and techniques to adjust the length and alignment of pushrods and connectors for optimal control surface operation.

• Securely tighten locking mechanisms to prevent them from loosening during flight, but avoid over-tightening, which can lead to stress or damage to the components.

4. Considerations:

• Choose links and connectors that are appropriate for your aircraft's size, weight, and flight characteristics.

• Regularly inspect links and connectors for signs of wear, damage, or loosening, and replace or repair them as needed to maintain proper function and structural integrity.

• Properly installed and maintained links and connectors are essential for safe and precise control of your RC plane, so invest time and attention to ensure they are installed correctly.

Links and connectors may seem like small and straightforward components, but they play a crucial role in the overall performance and maneuverability of RC planes. By choosing the right type of link and connector and ensuring proper installation and maintenance, you can enjoy smooth and responsive control surface operation during flight.
