Product Description

DuBro Nylon Control Horns 1 Left & 1 Right #105 (2pcs)

Establish ultra-precise mechanical linkage geometry and crisp control surface response with the DuBro Nylon Control Horns 1 Left & 1 Right (#105). Molded from high-grade, vibration-resistant white nylon, this classic hardware set features an offset 1 Left and 1 Right horn design engineered for perfectly symmetrical pushrod alignment across opposing ailerons, elevators, rudders, or flaps. Standing 1-1/8 inches (28.5mm) tall with four distinct pushrod mounting holes, these control horns enable pilots to fine-tune linkage mechanical advantage, control throw, and servo resolution with absolute precision.

This reliable control surface hardware serves as an essential build component across various aviation and prototyping disciplines:

• RC Hobby & FPV Flight: Provides a lightweight, high-strength linkage connection for small, medium, and sport fixed-wing models, ensuring chatter-free aerobatic authority and smooth, predictable tracking.

• Educational & STEM Airframe Projects: Serves as an ideal teaching hardware set for high school and university aerodynamics labs, allowing students to physically experiment with control surface mechanical leverage, pushrod geometry, and torque delivery.

• sUAS & Enterprise UAV Flight Testing: Functions as a durable, highly repeatable hardware staple for lightweight surrogate testbed aircraft, custom flight control surface prototypes, and field-repairable drone airframes.

Assembly Tip: When mounting to balsa or foam control surfaces, place a tiny drop of medium CA glue or threadlocker on the threads of the included 2-56 screws after tightening them into the self-threading backing plates. This creates a permanent, vibration-proof mechanical clamp that will not compress or loosen over time.

Key Features:

• Symmetrical Left/Right Offset Design: Includes one left-handed and one right-handed horn to maintain identical pushrod geometry and uniform linkage angles on opposing wings or elevator halves.

• Four Precision Adjustment Holes: Provides multiple leverage options along the 1-1/8" height to effortlessly adjust control surface throw for smooth trainer cruising or high-rate aerobatic maneuvers.

• Tough Vibration-Dampening Nylon: High-strength white nylon resists fuel corrosion, UV degradation, structural fatigue, and mechanical wear under high air loads.

• Secure Sandwich Clamp System: Includes self-threading nut plates and 2-56 screws to firmly clamp across control surface tabs without crushing underlying foam or balsa wood.

• Ultra-Lightweight Profile: Weighing just 2 grams per side, this complete hardware set adds negligible deadweight to critical tail or wing assemblies.
