Dubro 2-56 Threaded Ball Link RC Aircraft Spare Part - DUB181

The Dubro 2-56 Threaded Ball Link (DUB181) is a precision control linkage component designed for use in RC aircraft pushrod and servo linkage systems. Ball links allow a rod end to pivot freely in multiple directions, preventing binding in control runs where the angle between the servo arm and control surface horn changes through the range of movement. The 2-56 thread size is a standard imperial sizing widely used in small to mid-size RC aircraft linkage hardware.

• 2-56 threaded shank for compatibility with standard 2-56 pushrods and threaded rods

• Suitable for aileron, elevator, and rudder control runs where precise, free movement is needed
