Du-Bro DUB306 Kwik Link with 12" Rod — 4-40

The Du-Bro® DUB306 Kwik Link with 12" Rod is a complete, adjustable 4-40 control linkage assembly for RC aircraft, cars, and boats. The Kwik Link snaps onto control horns and servo arms without tools and allows quick, tool-free length adjustments in the field — making it easy to fine-tune control throws and neutral positions without disconnecting the entire linkage. The 4-40 thread provides greater strength than 2-56, making this a solid choice for higher-load linkage applications on larger platforms. The included 12-inch rod gives you a solid starting point that can be trimmed to your exact required length.
