Ready to run straight out of the box, this buggy features a robust black-anodized aluminum chassis inspired by the TLR world-champion buggy, ensuring durability and a premium feel. The inclusion of a micro servo and fully proportional electronics means you get responsive steering and throttle control, making every drive feel smooth and precise. Powered by a 2S 30C LiPo battery (7.4V 350mAh), the Losi Micro B offers impressive speed and runtime, while the USB-C charger makes recharging quick and convenient. The SLT2 2.4GHz radio system provides interference-free control, and the adjustable oil-filled shocks allow you to fine-tune the suspension for different surfaces. With its championship-winning DNA and high-quality components, the Losi Micro B stands out as a top choice for micro RC racing.
Included Accessories
Everything you need to get started with the Losi Micro B 2WD buggy is included right in the box. You’ll find a 7.4V 350mAh 2S 30C LiPo battery for strong, consistent power, along with a USB-C charger for fast and easy charging. The Spektrum SLT2 2.4GHz radio transmitter ensures reliable, fully proportional control, while the instruction manual guides you through setup and operation. For tuning and customization, the buggy comes with pre-load clips and optional shock fluid, allowing you to adjust the suspension to match your racing style. The throttle-limiting switch on the transmitter lets you activate rookie mode, capping the buggy’s speed at 50% or 75%—perfect for new drivers or everyday low-speed fun. With all these included accessories, the Losi Micro B is truly ready to run, making it easy to jump straight into the action.
Design and Build Quality
The Losi Micro B borrows its look and layout from Losi’s championship‑winning TLR 1/10‑scale race buggies, scaled down to 1/24 but still focused on performance. The black‑anodized aluminum chassis is a standout at this size, offering greater stiffness and durability than plastic‑deck micros.
Oil‑filled shocks on all four corners are another premium touch, giving better damping than friction shocks and allowing tuning via different shock oils, springs, and preload clips. Pro‑Line branded racing body wheels and tires complete the race‑bred look and deliver solid traction on carpet, hardwood, and smoother outdoor surfaces.
Performance, Speed, and Handling
For a buggy that can fit in your hand, the Losi Micro B is impressively quick, with a claimed top speed of more than 13 mph on the included 2S LiPo pack. That speed, combined with proportional steering and throttle, makes it feel like a scaled‑down club racer rather than a basic beginner toy.
Handling benefits from the oil‑filled shocks and low‑slung aluminum chassis, which help it stay composed over bumps and when landing jumps. Some hobbyists note that the turning radius is not as tight as a purpose‑built indoor racer, but still consider it a big step up in drivability compared to many micro platforms. On low‑pile carpet or taped‑off indoor tracks, the buggy feels agile, controllable, and genuinely fun to push hard.
Battery Life and Charging
Unlike many RTR micros that run out around 8 minutes, the Losi Micro B includes a 350 mAh 2S LiPo battery that can deliver close to 20 minutes of runtime on a full charge. That makes a noticeable difference if you’re running multiple packs back‑to‑back or sharing the buggy between family members.
Charging is handled by a simple USB‑C charger that can refill the pack in under an hour, which is much quicker than the basic wall chargers that can take 2–5 hours on many entry‑level RTRs. For casual indoor bashing, one or two packs are usually enough to keep you running almost continuously.
Radio System and Rookie‑Friendly Features
The included Spektrum SLT2 2.4GHz radio offers fully proportional control along with a throttle limit switch on the back of the transmitter. You can cap the speed at 50% or 75% of full throttle, which is ideal when handing the radio to kids or brand‑new drivers.
The transmitter requires AA transmitter batteries, which are typically included in the package or recommended as essential accessories for operation. Having AA transmitter batteries ensures the remote control is ready to use right out of the box, adding to the convenience and user-friendly experience.
This “rookie mode” keeps the buggy manageable on small tracks or in tight living spaces while new drivers learn to balance steering and throttle. Once they are comfortable, flipping back to 100% unlocks the full 13+ mph performance for more advanced driving.
Upgrades, Tuning, and Aftermarket Support
Out of the box, the Losi Micro B is fully RTR, but it also has an upgrade path for enthusiasts. Losi offers option parts, including aluminum pieces and replacement electronics, and there is growing community interest in experimenting with gearing, motors, and suspension setups.
Early racers point out that an adjustable motor plate and expanded gearing options would help when tuning for racing, speed runs, or brushless conversions, and some expect aftermarket solutions to appear. Aluminum hubs, spindles, and shims are also talked about as desirable upgrades for those planning to push the buggy hard on track.
Comparison to Other Models
Compared to other micro buggies and RC cars in its class, the Losi Micro B 2WD buggy stands out for its high-performance features and thoughtful design. Unlike many entry-level micro vehicles, the Losi Micro B boasts a black anodized aluminum chassis for superior strength and rigidity, as well as fully proportional electronics for precise control. Its adjustable oil-filled shocks and powerful 2S 30C LiPo battery provide a smoother ride and more speed than most competitors. The advanced SLT2 2.4GHz radio system offers reliable, interference-free operation, while the TLR-inspired design gives it a true racing pedigree. Whether you’re looking for a micro buggy that excels in RC racing or simply want a durable, responsive car for everyday fun, the Losi Micro B’s combination of championship-winning features and user-friendly controls makes it a standout choice in the world of micro RC cars.
