Overview

The Tuning Screwdriver from Losi is the perfect tool for the nitro enthusiast or racer. Specially designed to meet the needs of nitro vehicles and engines, but more importantly those who use them. The extra long blade allows easy access to even the most remote areas of 1/10, 1/8 and all types of monster vehicles. The ergonomically designed handle offers unmatched comfort and control. A special high-temperature tapered silicone rubber “stopper” tip on the handle is used to plug the hot exhaust pipe to kill the engine when done running. No more burned fingers or messy marks to deal with. No more need to burn finger tips or grind something into the flywheel to kill the engine.

Overview

The Losi Tuning Screwdriver T-LOSA99167 is an essential tool for any nitro RC enthusiast or racer in the UK who demands precision, comfort and safety when tuning and maintaining their RC vehicles. This specialist screwdriver has been purpose-engineered by Losi to address the unique challenges faced by nitro engine tuning, particularly for 1/10, 1/8 and monster truck scale vehicles. Whether you're a competitive racer fine-tuning carburetor needles or a weekend basher making quick adjustments, this tool delivers the ergonomic design and practical features that serious RC car UK hobbyists expect.

What sets the Losi Tuning Screwdriver apart from standard workshop tools is its complete focus on the nitro RC environment. The design acknowledges two critical pain points: accessing tiny adjustment screws in confined engine bays, and safely handling hot exhaust systems after running your RC nitro truck or buggy. This is not a generic multi-purpose screwdriver—it's a purpose-built tool that understands the specific needs of the nitro RC community and delivers a solution that makes tuning faster, safer and more enjoyable.

Backed by Losi's reputation for quality RC products and genuine innovation, the T-LOSA99167 represents a smart investment for anyone serious about getting the most from their nitro-powered RC car UK setup. The combination of extended reach, comfortable handling and the innovative exhaust port safety feature makes this tuning screwdriver an indispensable addition to any RC enthusiast's toolbox.

Key Features

  • Extra-Long Blade — The extended blade length provides easy access to remote areas and hard-to-reach adjustment screws on 1/10, 1/8 and monster truck vehicles, eliminating the frustration of struggling with standard-length tools in confined engine compartments where carburetor needles and other critical tuning components are located.
  • Ergonomically Designed Handle — The thoughtfully contoured grip offers unmatched comfort and precise control during sensitive tuning work, reducing hand fatigue during extended RC tuning sessions and allowing you to make fine adjustments with confidence and accuracy.
  • High-Temperature Tapered Silicone Rubber Tip Stopper — A special rubber stopper on the handle is specifically designed to safely plug the hot exhaust pipe and kill your nitro engine when you're done running, eliminating burned fingers and the need to grind the starter or flywheel to stop the engine—a genuine safety innovation for the nitro RC UK market.
  • Purpose-Built for Nitro Vehicles — Unlike generic screwdrivers, this tool has been specially designed with the nitro enthusiast in mind, addressing the specific tuning and maintenance needs of nitro RC cars, buggies, trucks and monster trucks across all popular scales.
  • Safe Exhaust Management — The high-temperature tapered rubber tip eliminates the messy and painful practice of finding alternative methods to stop your RC engine, providing a professional, safe and repeatable way to kill your motor without risk of injury or damage to your vehicle.

Technical Performance

The Losi Tuning Screwdriver T-LOSA99167 is engineered with precision-focused materials and construction to deliver reliable performance in the demanding environment of RC nitro tuning and maintenance. The extended blade design provides the reach necessary to access needle valves and adjustment screws that would otherwise be inaccessible with standard tools, making it an essential instrument for anyone running 1/10, 1/8 or monster truck scale nitro vehicles. The handle construction incorporates ergonomic principles to reduce hand strain and fatigue, crucial when you're making minute adjustments that require fine motor control and sensitivity to feedback. The high-temperature tapered silicone rubber tip stopper represents genuine engineering innovation for the nitro RC community; standard silicone construction would fail or melt at exhaust pipe temperatures, but Losi's special high-temperature formulation maintains its integrity and grip reliability even when in contact with a freshly-run hot exhaust system. The tapered design ensures a secure seal on exhaust ports of varying diameters, making it compatible across different nitro RC engine types and configurations. This is a tool built by engineers who understand nitro RC vehicles, not a repurposed workshop tool adapted for hobby use—every design decision reflects real-world experience with 1/10 and 1/8 scale nitro racing and bashing applications.

Frequently Asked Questions

  • Is the Losi Tuning Screwdriver suitable for all RC nitro vehicles? — Yes, this tool is specifically designed for nitro vehicles across all popular scales including 1/10, 1/8 and monster truck configurations. The extra-long blade reaches adjustment screws in confined engine bays regardless of chassis design, and the high-temperature rubber tip stopper works with any nitro engine exhaust port.
  • Can I use this screwdriver for electric RC cars as well? — Whilst the tuning screwdriver can be used for general RC maintenance on electric vehicles, its features are specifically engineered for nitro engines. The high-temperature exhaust stopper is unique to nitro operation and has no application with electric motors, though the extended blade can certainly help with any hard-to-reach adjustments on electric RC car UK setups.
  • What makes this different from a standard screwdriver? — This is purpose-built for RC nitro tuning rather than general workshop use. The extra-long blade provides reach into confined engine bays where carburetor needles are located, the ergonomic handle offers the control needed for precise tuning, and most importantly, the high-temperature silicone rubber tip stopper safely kills your engine without burned fingers or damage to the flywheel.
  • How does the exhaust pipe stopper work? — The tapered silicone rubber tip on the handle is designed to plug the hot exhaust pipe on your nitro engine, cutting off the air flow and stopping combustion. The high-temperature silicone formulation withstands exhaust heat without melting or degrading, and the tapered profile accommodates different exhaust port sizes across various nitro engines.
  • Is this tool safe to use on a running engine? — No, the stopper should only be used on a freshly-stopped engine with a cooling exhaust system. Never attempt to use this tool on an actively-running engine. Always allow your nitro RC engine to reach operating temperature and then use the stopper to safely shut down the motor when you're finished running.
  • What scale RC vehicles will this fit? — The Losi Tuning Screwdriver is designed for 1/10, 1/8 and all types of monster vehicles. The extra-long blade provides access to engine bays across these scales, and the high-temperature rubber stopper tip accommodates most nitro engine exhaust ports found in these size classes.
