Overview
The Losi Servo Arm in aluminium is a premium replacement chassis component designed for the Losi 1/16 Mini-B and Mini-T 2.0 RC buggies. This high-quality upgrade part is engineered to improve your RC buggy's steering response and overall handling characteristics. Whether you're a seasoned RC enthusiast in the UK or just getting started with 1/16 scale RC buggies, this aluminium servo arm represents a significant performance upgrade over standard plastic components. The part features a 20-tooth spline connection and is manufactured to the exacting standards that Losi is recognised for worldwide.
This servo arm is specifically engineered to work with the Spektrum SPMSSX107 servo and is part of Losi's comprehensive range of aluminium upgrades for the Mini-B platform. As a replacement part, it allows you to refresh your RC buggy's steering system with a more durable, responsive alternative. The aluminium construction provides superior rigidity compared to plastic alternatives, which directly translates to more precise steering input and improved cornering performance on the track.
For RC car enthusiasts looking to optimise their Mini-B or Mini-T 2.0 setup, this aluminium servo arm is an essential upgrade. The ready to run RC buggy platform becomes even more competitive with this performance-enhancing component installed, making it an ideal choice for both recreational bashers and serious racers alike.
Key Features
- Aluminium construction — Manufactured from high-grade aluminium to provide superior strength and durability compared to plastic alternatives, ensuring your steering system remains rigid and responsive through demanding track sessions and outdoor bashing.
- Improves steering response — The rigid aluminium design specifically enhances steering feedback and precision, allowing for faster, more accurate steering input which translates directly to better lap times and improved handling through corners.
- 20-tooth spline connection — Features a precisely engineered 20-tooth spline that matches the Spektrum SPMSSX107 servo specification, ensuring perfect fitment and reliable power transmission from your servo to the steering linkage.
- Direct replacement part — Designed as a drop-in upgrade for the Mini-B and Mini-T 2.0, making installation straightforward without requiring chassis modifications or additional engineering work.
- Enhanced durability — The aluminium material resists the flex and wear that plastic servo arms are prone to, extending the lifespan of your steering system and reducing maintenance downtime between races and bashing sessions.
- Precision engineering — Manufactured to Losi's renowned engineering standards, ensuring dimensional accuracy and perfect compatibility with all other Mini-B and Mini-T 2.0 chassis components.
Technical Performance
The Losi Servo Arm represents a significant engineering upgrade for 1/16 scale RC buggies. The aluminium construction provides a material hardness and rigidity that fundamentally improves steering characteristics compared to standard plastic servo arms. The 20-tooth spline interface is precisely machined to work seamlessly with the Spektrum SPMSSX107 servo, ensuring optimal power transmission and eliminating any play or flex in the steering linkage. When paired with the Mini-B's TLR 22 suspension geometry and mid-motor configuration, this aluminium servo arm enables the chassis to deliver the kind of balanced steering and traction that drivers expect from a scaled-down version of a championship-winning platform. The aluminium material also dissipates heat more effectively than plastic, which becomes important during sustained high-speed driving sessions. The precision engineering maintains tight tolerances throughout the component, preventing the wear patterns that can develop in plastic parts over time, thus maintaining consistent steering feel lap after lap. For drivers of brushless RC buggies running competitive setups, this upgrade directly contributes to improved lap times and more predictable handling characteristics across different track surfaces and conditions.

Frequently Asked Questions
- Will this servo arm improve my Mini-B buggy's performance? — Yes, the aluminium construction provides significantly improved steering response compared to plastic alternatives. The rigid material eliminates flex in the steering linkage, which directly improves precision and allows you to make faster, more confident steering inputs during racing and bashing. This upgrade is particularly beneficial if you're running a competitive setup or spending extended time on the track.
- Is this compatible with all Mini-B and Mini-T 2.0 models? — This servo arm is compatible with the Losi 1/16 Mini-B and the 1/18 Mini-T 2.0 range, including the Mini-JRX2, Mini-B Brushed RTR, Mini-B Brushless RTR variants, and the Mini-T 2.0 V2 in both Red and Blue options. The 20-tooth spline design matches the standard Spektrum servo specification for these platforms.
- What servo do I need to use with this servo arm? — This aluminium servo arm is specifically engineered to work with the Spektrum SPMSSX107 servo, which features the matching 20-tooth spline interface. Using this compatible servo ensures proper fitment and optimal steering response from your Mini-B or Mini-T 2.0 RC buggy.
- Is this upgrade suitable for beginners? — This is a direct replacement servo arm upgrade rather than a beginner-level component. If you already own a Mini-B or Mini-T 2.0 and want to improve your buggy's steering characteristics, this is an excellent upgrade. However, if you're brand new to RC buggies, you may want to start with a complete ready to run RC buggy package and add upgrades like this once you're familiar with the basics of RC ownership.
- Why is aluminium better than plastic for servo arms? — Aluminium offers several advantages over plastic in RC applications. It provides superior rigidity, which prevents flex and maintains consistent steering geometry under load. It also offers better durability, resisting the creep and wear that plastic experiences over time. Additionally, aluminium dissipates heat more effectively, which is beneficial during sustained driving sessions. These properties combine to deliver more responsive, consistent steering feedback and improved lap times.
- Will this part fit my Losi buggy? — This servo arm is specifically designed for the Losi 1/16 Mini-B and 1/18 Mini-T 2.0 range. It will not fit other Losi platforms or different manufacturer's chassis. Check the compatible model list to confirm your specific vehicle variant is supported.
