RC enthusiasts, listen up! This 25T aluminum servo arm horn is exactly what you need to upgrade your 1/10 scale RC car, boat, or airplane. Made from tough aluminum alloy using precision CNC machining, this red servo horn is built to handle serious torque without flexing or breaking. Measuring 32mm long and 7mm thick, it features mounting holes at 18mm and 21mm centers with a 3mm aperture and 6mm servo output fit. The split clamp design includes a bolt to secure it tightly onto your servo output shaft. Installation is straightforward - just remove your old servo horn, attach your steering link to this new one, slide it onto the output shaft, and tighten the center screw. You'll notice immediately how much more precise your steering feels with this durable aluminum upgrade. Quick heads up though - this is just the servo arm itself, your servos aren't included. But if you're looking to improve your RC vehicle's performance and durability, this 25T aluminum servo horn is totally worth it. Perfect for replacing those plastic horns that always seem to strip out when you need them most!
