RC Airplane Control Horn 19x17mm 4-Hole 1.4mm

These RC Airplane Control Horns are high-quality linkage components engineered for accurate and reliable control surface actuation on fixed-wing RC aircraft. Manufactured from durable rigid nylon plastic, these 19×17mm control horns offer a slightly taller profile than standard horns, providing increased mechanical advantage and greater control surface throw. The four-hole design gives pilots maximum flexibility in fine-tuning control sensitivity, throw rates, and mechanical advantage for diverse flying styles and aircraft types.

Each control horn features a 1.4mm hole diameter perfectly sized for lightweight wire linkages, Z-type push rods, and mini RC clevises commonly used in smaller to medium-sized RC aircraft. The additional fourth hole compared to three-hole designs expands your adjustment range, enabling everything from ultra-precise low-rate settings for smooth training flight to aggressive high-rate throws for aerobatic maneuvers. The integrated base plate provides a wide and stable mounting footprint for secure adhesive or screw attachment directly onto control surfaces.

Suitable for foam, balsa, and composite fixed-wing aircraft including park flyers, gliders, trainers, sport planes, and warbirds, these control horns serve as excellent replacements for damaged components or as building blocks for scratch-built projects. The taller 19mm height creates additional leverage for improved control surface response, making them ideal for aircraft requiring increased throw. Ultra-lightweight construction ensures minimal impact on aircraft balance and overall weight while maintaining the rigidity needed for precise flight control.
