Overview
The Du-Bro Heavy Duty Dual Control Horn is engineered for large RC aircraft requiring robust, precise control surface linkage. Molded from high-strength nylon, the dual-arm design ensures even, in-line movement of the control rod — eliminating twisting forces and delivering smoother, more accurate response.
Each horn includes a 1" square support plate with socket head mounting bolts and a heavy-duty swivel ball link sized for 4-40 control rods. Sold as a 2-pack for convenient pair installation.
