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 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. Versatile, affordable, fast, and fun, the Mini-B makes an excellent starting point for any aspiring RC racer.
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.
Many improvements have been made to even small details, and they combine to make a major difference on the track. The transmission case now accepts sway bars. The front bulkhead has been thickened for improved durability. An updated servo saver increases consistency, and updated shock cartridge spacers add smoothness. That's just to name a few. The Mini-B 2WD brushless racing buggy also comes with a high-capacity Spektrum Smart 810mAh 2S LiPo battery and a Smart USB charger for long run times and easy, accurate recharging.
Losi has outfitted the Mini-B with Wide Body Rib front tires and Big Shot rear tires — recreations of highly popular Losi treads from the early 2000s.
The Mini-B chassis is tunable and option parts are also available, so as your racing experience grows, you'll be able to fine-tune your mini buggy's performance to keep seeing better racing results. Make your move into RC racing today with the Losi Mini-B 2WD brushless racing buggy. Whether at your local track or on a PVC pipe track set up in your basement, it's sure to fire up your competitive spirit.
The mid-motor configuration of the Losi Mini-B 2WD brushless racing buggy creates a well-balanced chassis on high-traction surfaces, allowing for better performance on multiple racing surfaces and also balancing out steering and traction.
The Mini-B has been designed with a 1.5mm thick, 6061-T6 aluminum chassis plate that provides strength and durability along with rigidity that vastly improves racing performance.
The injection-molded oil shocks have threaded shock collars that allow for easy preload and ride height adjustments to quickly adjust to the track after your warm up laps. The shock bodies also feature a bottom-loading, rebuildable shock cartridge with dual O-rings that help to keep the oil in the shocks. As an option, the shocks can be tuned using different spring rates and TLR shock oil weights available separately.
The included 7.4V 810mAh 2S Smart G2 50C LiPo battery not only offers high capacity for long run times, but also stores its charging parameters on an integrated microchip. That data uploads to the included Smart charger automatically when the battery is connected. Safe, accurate charging begins immediately.
Using innovative Spektrum Smart technology, the included 2S LiPo battery communicates automatically with the supplied Smart USB charger the moment you plug it in. You don't have to worry about making the correct charge settings — it's done for you. Charging is convenient, safe, and easy!
The tires included with the Mini-B 2WD brushless racing buggy recreate Losi's popular Big Shot rear tires and Wide Body Rib front tires from the early 2000s.
The metal gear transmission is engineered to handle the massive power output of the Mini-B's brushless motor system. All of the gears are ball bearing supported for a smooth, efficient transmission.
The entire vehicle is equipped with ball bearings for maximum smoothness and efficiency — a must-have for racing! (Less steering.)
The Spektrum SX108 steering servo turns the Mini-B tires with over 40 oz-in of torque. Its servo saver gives a consistent feel to the steering while protecting the servo from sudden jolts caused by bumping with other vehicles on the track.
In addition to providing interference-free control, the included Spektrum SLT2 2.4GHz transmitter offers many useful features including steering trim, steering rate, and steering reversing. With its throttle limiting switch, beginners can limit their access to the buggy's full speed potential from 50% to 75% to 100% — perfect for learning RC control skills gradually and safely.
The Spektrum SR315 3-Channel Dual Protocol receiver delivers superb range and response with a solid 2.4GHz link. It has an extra port for racing transponders and accommodates upgrades to higher-performance Spektrum transmitters without the need for a new receiver.
Competing, customizing, upgrading — you can do it all, RC style, with the Losi Mini-B 2WD. A full line of option parts is available for making this racing buggy all your own.
Small improvements make a big difference at the track! After studying the Mini-B and listening to racers, Losi engineers found many ways to refine its design. The shock cup height has been adjusted to keep the spring secure. A bearing spacer added in the rear hub lets you tighten the rear wheel with confidence. A new ball cup material provides better function and durability. The transmission case accepts sway bars, and the front bulkhead has been thickened to increase strength. The new slipper plate offers a more consistent feel under brushless power, and the servo saver increases consistency while making the steering feel more direct.
