This servo horn is perfect for anyone replacing a damaged servo horn on their RC car, upgrading to higher quality components, or building an RC vehicle from scratch.

Key Features

• Black Anodised Aluminium Construction — The body is crafted from premium aluminium and finished with professional black anodising, providing excellent durability, corrosion resistance and a modern aesthetic appearance that looks great on any RC car build without adding unnecessary weight to your vehicle.
• Silver Chamfered Edging — Precision-engineered silver chamfered edges create a refined, finished look that sets this servo horn apart from basic alternatives, giving your RC build a professional appearance whilst also reducing stress concentration at edges during high-stress servo movements.
• Hollowed Centre Design — The strategic hollow centre reduces weight without compromising structural strength, which is particularly beneficial for RC vehicles where keeping unsprung mass to a minimum improves handling characteristics and servo response time during precise steering inputs.
• Dual Mounting Points — Two throw positions at 15mm and 19mm allow you to select the steering arm geometry that best suits your RC car's setup, steering response characteristics and driving conditions, giving you precision control over your vehicle's handling balance.
• 25T Spline Compatibility — This servo horn features the industry-standard 25T spline design compatible with Futaba and Savox servos, two of the most popular servo brands used in RC cars, buggies and trucks throughout the UK RC racing community and hobby market.
• Screw and Clamp Fixing System — The dual-securing system combines traditional screw mounting with an additional clamp mechanism that you tighten lightly for enhanced security, preventing servo horn slip during aggressive steering inputs and ensuring your RC steering remains responsive and accurate throughout your session.
• Precise 31x7mm Dimensions — The carefully engineered dimensions are optimised for clean fitment and alignment, ensuring your servo horn seats perfectly on your 25T spline servo with no binding or misalignment that could cause premature wear or steering lag in your RC setup.

Technical Performance

The RC Overhaul 25T Aluminium Clamp Servo Horn represents a significant upgrade over plastic alternatives commonly found on budget RC cars. The aluminium construction provides superior rigidity and heat dissipation compared to polymer materials, which is critical during extended RC driving sessions where servo heat can accumulate. The black anodised finish provides a protective oxide layer that resists corrosion from moisture, dirt and salt encountered during outdoor RC driving, ensuring longevity even with regular maintenance-free use. The screw and clamp fixing mechanism works by first screwing the horn onto the servo output spline in the traditional manner, then lightly tightening the clamp screw which applies radial pressure around the horn's bore, effectively locking it in place against potential rotation or slippage that can occur during hard steering inputs or servo-grinding situations common in competitive RC racing. The dual throw positions at 15mm and 19mm allow steering geometry customisation; the 15mm setting provides faster, more direct steering response suitable for technical tracks with tight corners, whilst the 19mm setting offers greater mechanical advantage for more sensitive steering feel across varied terrain. The hollow centre design is precision-engineered to maintain structural integrity whilst reducing rotational inertia on the servo, allowing faster steering response and quicker directional changes crucial for RC racing performance. Built from high-grade aluminium with professional anodising throughout, this servo horn will outperform and outlast multiple plastic alternatives, making it a cost-effective investment for any serious RC enthusiast building or upgrading their RC car.

Frequently Asked Questions

• Is the RC Overhaul 25T servo horn compatible with my RC car? — This servo horn is designed for any RC servo featuring a 25T spline, which includes popular brands like Futaba and Savox. If your RC car currently uses a 25T servo, this horn will fit directly. Check your servo's specification to confirm the spline type before purchasing. If you're unsure, our team at RC Model Shop can help identify your servo type and confirm compatibility.
• What is the advantage of aluminium over plastic servo horns? — Aluminium servo horns offer superior strength, rigidity and durability compared to plastic alternatives commonly found on budget RC cars. Aluminium dissipates heat better during extended RC driving sessions, resists bending under load, and will typically outlast multiple plastic horns, making it a better long-term investment for your RC setup. The black anodised finish also provides corrosion protection for outdoor RC use.
• How do I install the screw and clamp fixing system? — Installation is straightforward: first screw the horn onto your servo output spline using the provided screw in the same way you would with any servo horn. Once seated, lightly tighten the clamp screw which applies pressure around the horn bore, locking it firmly in place and preventing any rotation or slippage during steering inputs. Do not over-tighten the clamp as this can strip the mechanism or damage the servo spline.
• What is the difference between the 15mm and 19mm throw positions? — The throw position refers to the distance from the servo horn's centre to the ball joint mounting point. The 15mm position offers quicker, more direct steering response with less mechanical advantage, whilst the 19mm position provides greater mechanical advantage for more sensitive steering feel. Your choice depends on your RC car's setup, servo torque, steering linkage geometry and personal driving preference.
• Is this servo horn suitable for beginners? — Yes, this servo horn is excellent for beginners and experienced RC drivers alike. Its robust aluminium construction and reliable clamp fixing system make it more durable than plastic alternatives, making it ideal for learning without worrying about frequent horn replacement. The straightforward installation process requires no special tools beyond a small screwdriver.
• Will this servo horn work on my RC buggy, truck or crawler? — This servo horn is compatible with any RC vehicle using a 25T spline servo, including RC buggies, RC trucks, RC truggies, RC crawlers, RC short course trucks and RC monster trucks. It's equally suitable for on-road and off-road RC applications, competitive racing and casual bashing.
