A Control Horn (Big 4 Holes) is an essential linkage component used in RC aircraft, drones, and model control systems to connect the servo pushrod to control surfaces such as the aileron, elevator, or rudder. Designed with four large holes, it allows adjustable linkage positions for precise control and improved movement range. Made from durable and lightweight material, this control horn provides strong and reliable performance during flight operations. It ensures smooth transfer of servo motion to control surfaces, making it ideal for large RC planes, UAV projects, and heavy-duty control applications.
he nylon control horns are used to connect control surfaces such as rudders and ailerons to the airplane. The nylon control horns sandwich the control surface between the two horn bases and offer a no slip installation.
When building a larger RC plane with a wingspan over 1000mm, the aerodynamic forces on your control surfaces increase exponentially. Standard small horns found in cheap kits simply can't handle the torque generated during loops or sharp banking.
