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. Whilst growing numbers of Losi mini RC fans 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 versatile, affordable, fast, and fun machine that makes an excellent starting point for any aspiring RC racer in the UK and beyond.
Straight out of the box, the ready-to-run RC buggy is completely assembled and ready to hit the track with everything you'll need included. 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. Whether you're looking for a quality brushless RC buggy for beginners or an intermediate racer wanting an affordable, nimble machine, the Mini-B delivers track-proven performance without breaking the bank. The Mini-B offers the durability to withstand crash impacts with other competitors, making it ideal for both recreational bashers and competitive racers.
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. Many improvements have been made to even small details, and they combine to make a major difference on the track. Whether at your local track or on a PVC pipe track set up in your basement, the Losi Mini-B is sure to fire up your competitive spirit and deliver years of racing enjoyment.

- Spektrum SR315 Dual Protocol Receiver — This 3-channel receiver delivers superb range and response with a solid 2.4GHz link, includes an extra port for racing transponders, and accommodates upgrades to higher-performance Spektrum transmitters without requiring a new receiver.
- Spektrum SX108 Micro Digital Metal Gear Servo — The steering servo turns the Mini-B tyres with over 40 oz-in of torque, featuring a servo saver that gives consistent steering feel whilst protecting the servo from sudden jolts caused by competitor contact on the track.
- Option Parts Available — As your racing experience grows, a full line of optional components allows you to fine-tune your buggy's performance, customise its appearance, and upgrade components to match your evolving racing needs.
Technical Performance
The Losi Mini-B 2WD brushless buggy represents a significant engineering achievement in the mini-scale RC racing category. Built around a robust 1.5mm thick 6061-T6 aluminium chassis plate measuring 272mm in length, 178mm in width, and standing 102mm tall, this compact racer delivers impressive performance from its Spektrum FIRMA 6000KV brushless motor working in conjunction with an integrated ESC. The motor's substantial torque output is managed through a metal gear transmission featuring a 60-tooth spur gear and 18-tooth pinion, creating a 2.714:1 internal gear ratio with 0.5MOD pitch gears. This combination allows the Mini-B to achieve speeds up to 30 mph whilst maintaining the control and handling characteristics essential for competitive racing. Power comes from the included Spektrum Smart G2 2S LiPo battery rated at 810mAh with 50C discharge capability, providing a 7.4V nominal voltage perfectly matched to the brushless system. The independent suspension incorporates 7mm bore, oil-filled shock absorbers with threaded collars for easy adjustment, complemented by full ball bearings throughout the drivetrain (excluding steering) for smooth, efficient operation. The transmission case now accepts sway bars for those seeking additional tuning options, whilst the strengthened front bulkhead provides increased durability during competitive racing. The EC2 connector type ensures compatibility with standard Spektrum charging systems, and the integrated braking system is controlled directly through the ESC. Whether you're racing on a dedicated track or a basement PVC circuit, the Mini-B's refined engineering delivers predictable, competitive performance suitable for intermediate racers and serious enthusiasts in the UK.
