Overview
Get the perfect start in RC racing with the affordable Losi Mini-B 2WD brushless buggy. Ever since introducing the first Mini-T stadium truck in 2003, Losi has been setting the bar higher and higher for mini-size RC racing performance. While growing numbers of Losi mini RC enthusiasts honed their skills on makeshift tracks built in their driveways and backyards, Losi kept pushing the limits of what mini RC vehicles can do—adding suspension engineering from the top-of-the-line TLR 22, for example, and installing powerful brushless electronics. It has all led to this: the Losi Mini-B 2WD brushless racing buggy, a ready to run RC car that combines versatility, affordability, speed, and fun in one impressive package.
Straight out of the box, the Mini-B brushless is completely assembled and ready-to-run with everything you'll need to hit the track. Though mini in size, the Mini-B offers the performance capabilities of larger RC racing buggies. Its efficient 2-in-1 brushless motor and ESC system can send it at 30 mph speeds on the back straight, complementing its predictable handling with the power to dive into a corner to make a pass and hit the jumps consistently. The Mini-B offers the durability to withstand crash impacts with other competitors. And with a suspension inspired by the prestigious TLR 22—a vehicle often seen on the podium at the most competitive 1/10 scale buggy races—the Mini-B handles like a high-end machine, agile in the corners and easy to jump. Whether you're looking for a brushless RC buggy for your local track, a PVC pipe track set up in your basement, or simply want to fire up your competitive spirit, this ready-to-run electric RC car delivers serious performance and reliability.

- Refined Design Details — Losi engineers have refined countless small details that make a big difference at the track: shock cup heights adjusted to keep springs secure, bearing spacers in the rear hub for confident wheel tightening, improved ball cup materials, transmission case now accepts sway bars, thickened front bulkhead for increased strength, new slipper plate for consistent feel under brushless power, and enhanced servo saver for more direct steering response.
- Track-Ready Out of the Box — Every component is pre-assembled and tested, meaning you can unbox this ready-to-run RC car, charge the battery, and head straight to the track with absolute confidence.
- Tunable and Upgradeable — As your racing experience grows, the Mini-B chassis is fully tunable with a complete line of option parts available, allowing you to fine-tune performance, experiment with different shock springs and oils, and customise your buggy to match your driving style and track conditions.
Technical Performance
The Losi Mini-B 2WD brushless buggy represents a significant leap forward in mini-scale RC racing performance. At 1/16 scale with dimensions of 272mm length, 178mm width, and 102mm height, the compact footprint makes it perfect for smaller tracks, basement racing, or driveway practice—yet it delivers real performance that rivals much larger vehicles. The heart of the system is the Spektrum FIRMA 6000Kv brushless motor paired with an integrated ESC, creating a seamless 2-in-1 combo that eliminates complexity whilst maximising power delivery. With a maximum speed of 30 mph powered by the included 7.4V 2S LiPo battery, the Mini-B proves that miniature RC buggies can be genuinely thrilling. The chassis employs a 0.5MOD gear pitch with an internal gear ratio of 2.714:1, 60-tooth spur gear, and 18-tooth pinion configuration, delivering responsive acceleration and smooth power transfer through a metal gear transmission with full ball bearing support. The independent suspension uses 7mm bore oil-filled shocks that are both rebuildable and adjustable, allowing racers to dial in the perfect setup for their specific track. The strong 1.5mm 6061-T6 aluminium chassis plate provides the structural rigidity needed for consistent handling whilst resisting the impacts that come with competitive racing. EC2 connectors ensure secure battery connections, whilst the integrated braking system is managed by the ESC for smooth deceleration. Build quality throughout is exceptional—every bearing is a ball bearing for efficiency, metal gears throughout the drivetrain handle brushless power reliably, and the water-resistant design means this RC buggy can handle damp conditions. For beginners exploring the world of brushless RC racing, this is a genuine race-ready platform; for experienced racers, it's an affordable way to maintain competitive skills at a different scale.
