RC hobbyists, listen up! If you're running Hitec servos and need a tough, reliable servo horn, this Apex RC Products set is a solid choice. This is their heavy-duty aluminum dual clamping servo horn, and you get TWO in the pack (part #8010). It's made from high-quality CNC machined aluminum, so it's strong and precise. It fits the standard 24-tooth spline that Hitec servos use. The 'dual clamping' design is the best part – it uses TWO screws to securely clamp down on the servo output shaft. This means a much tighter, slop-free connection compared to horns that just rely on a single screw. It also gives you two mounting positions for your pushrod or link: one at 20mm from center-to-center, and another at 24mm. This lets you fine-tune your steering or throttle geometry. Apex RC is a company run by hobbyists for hobbyists, so they make stuff they'd use themselves. If you're building or upgrading a car, truck, or plane and want a servo horn that won't strip or come loose, these aluminum clamping horns are a great upgrade over plastic ones.
