DU-BRO HD Adjustable Control Horn – Self-Aligning Heavy-Duty Horns

The DU-BRO HD Adjustable Control Horn is a strong, easy-to-install control horn made for larger RC airplanes. If you want a horn that is simple to mount, lines up perfectly, and delivers reliable control, this heavy-duty design is an excellent choice. One of the best features of this horn is its self-adjusting design. It automatically positions itself at a perfect 90° angle to your control surface—even when that surface is angled or tapered. This means you can install it without using shims, wedges, or extra adjustments. Just mount the horn, tighten the hardware, and it aligns itself for you. This patented design (U.S. Patent #7,040,571) saves time and ensures accurate setup every time. These HD horns are built to handle higher loads, making them ideal for bigger sport aircraft, scale models, aerobatic planes, and other RC aircraft that require strong, dependable control hardware. They also add a clean, professional look to your model while providing smooth and solid linkage movement.
