Key Features
- 90MM Length — The 90mm dimension provides optimal lever length for balanced steering response, offering the mechanical advantage needed for precise control without excessive servo strain. This size is engineered to match the servo geometry on FMS vehicles and compatible crawlers.
- Orange Colour — The bright orange finish makes these control horns easy to spot during maintenance, allowing you to quickly inspect the steering linkage for wear, cracks, or damage. The colour also provides aesthetic appeal on display models or finished builds.
- FMS OEM Quality — These are genuine original equipment manufacturer parts engineered and tested by FMS to the same standards as complete vehicles. Using OEM parts guarantees compatibility with FMS models and ensures long-term reliability.
- Durable Construction — Built to withstand the mechanical stresses of off-road driving, rock crawling, and aggressive steering inputs. Quality control horns are essential for maintaining steering precision and preventing linkage failure during challenging terrain.
- Servo Linkage Compatibility — Designed to work with standard servo splines and linkage systems used across FMS remote-controlled crawlers and buggies. These horns connect your digital servo directly to the steering mechanism for responsive control.
- Easy Installation — Control horns are straightforward to install or replace, requiring only basic RC maintenance skills and standard tools. Whether you are upgrading from worn parts or replacing a damaged horn, installation typically takes just minutes.
Technical Performance
The FMS 90MM Super Scorpion Control Horns represent precision engineering focused on delivering reliable steering performance in demanding RC applications. Control horns are critical steering components that transfer servo motor rotation into directional changes, making their quality and durability paramount. The 90mm length provides optimal mechanical advantage — long enough to give fine steering resolution and reduce servo load, yet short enough to maintain responsive handling without excessive play or backlash. The orange ABS or composite construction offers excellent strength-to-weight ratio, resisting impacts and vibration while remaining light enough to minimise inertia in the steering system. These horns are engineered to work with standard servo splines found on digital servos commonly used in FMS vehicles and other modern RC cars and crawlers. Whether your RC buggy or crawler operates on rocky trails, muddy terrain, or indoor surfaces, quality control horns ensure consistent steering response and reduce mechanical wear on your servo motor. The simple yet effective design has proven itself across thousands of FMS vehicles in the UK RC market and globally. Replacement or upgrade control horns should be inspected regularly for cracks, bent splines, or wear marks that might indicate linkage issues or excessive servo strain.

Frequently Asked Questions
- What are RC control horns and why do I need them? — Control horns are the mechanical components that connect your servo motor to your vehicle's steering linkage. They transfer the rotational movement of the servo into left and right steering inputs. Quality control horns ensure responsive steering, reduce servo wear, and prevent steering linkage failure during off-road driving.
- Will these FMS control horns fit my RC car? — The FMS 90MM Super Scorpion Control Horns are designed for FMS vehicles and compatible RC crawlers using standard servo spline connections. Check your vehicle's servo specifications and horn size requirements before ordering. If you are unsure of compatibility, our team at RC Model Shop can help identify the correct part for your model.
- How often should I replace control horns? — Control horns typically last many seasons of regular use, but should be inspected regularly for cracks, bent splines, or wear. If you notice sluggish steering response, increased servo noise, or visible damage to the horn, replacement is recommended. Having spare horns on hand is a good practice for serious RC enthusiasts.
- What is the difference between 90MM and other horn sizes? — Control horn length affects steering leverage and servo load. A 90mm horn provides a good balance between steering precision and servo strain. Longer horns offer finer control but require stronger servos, whilst shorter horns provide faster steering response with higher servo loads. The 90mm size is a popular mid-range option across RC crawlers and buggies.
- Are these genuine FMS parts? — Yes, RC Model Shop stocks only genuine FMS original equipment components. These control horns are manufactured by FMS to the same exacting standards as FMS complete vehicles, ensuring perfect compatibility and long-term reliability.
