About the Micro-B
TLR Champion Race Inspired
The Losi Micro-B 1/24 RTR 2WD Buggy captures the excitement of RC racing in a compact, highly maneuverable package that’s small enough to run almost anywhere. Inspired by TLR's World Champion buggy, this micro-sized racer delivers big performance and agility. Whether you're racing in your living room or on a homemade track, the Micro-B's precision engineering, compact size, and TLR-inspired design make it an ideal choice for both casual RC enthusiasts and those looking to share their passion for racing with friends and family. Its RTR (Ready-To-Run) design means no additional accessories are needed, making it an easy and budget-friendly entry point into the RC world.
Performance Oriented Components
The Micro-B features a black-anodized aluminum chassis, setting a higher standard for micro RC vehicles with its rigid, durable construction. This chassis is designed with front caster kick and side bends to offer superior strength, ensuring it can withstand the bumps and jumps of intense racing. Paired with fully adjustable oil-filled shocks, the buggy delivers excellent handling and a smooth ride over various surfaces. The Pro-Line Racing body, wheels, and tires give it an authentic look and performance edge, reminiscent of full-scale race-winning designs, adding to the realism and enhancing your racing experience.
Electronics & Drivetrain
At the heart of the Losi Micro-B is its powerful Spektrum 350mAh LiPo battery and fully proportional electronics, allowing for precise control and speeds of 13+ mph — insane for a vehicle of this size! The Spektrum SLT2 2.4GHz radio ensures interference-free racing, while a throttle limiter provides “rookie mode” settings for safe learning at 50% or 75% speed.

Here's a review from someone who actually has this little beast. The motor is smaller than most minis. But stock, it's plenty fast for Mini-z and even mini-b/t tracks. Jumps beautifully, handles like a dream. Like anything, could benefit from personal tuning, but out of the box it's a real performer. The 7mm hexes mean you can use scx24/fcx24 wheels and tires (definitely recommend 50mm OD or less to save the factory electronics). Long story short, get it. Best $100 I've spent in a long time, and the aftermarket is only going to make them more awesome
Fun buggy for inside the house. I keep it on an end table next to the couch. I have been using it a lot off and on while watching TV. It does slide around a lot on hardwood floors on 100% throttle setting, 50% setting is about perfect on the wood floors. Get one!
WOW! Being in the RC hobby since the early 1980s I am really impressed with this Micro B. Videos don’t do it justice. Don’t let the tiny size fool you. Even with the transmitter set on 50% setting it moves out. Switch it to 100%, it’s on and gone. Gill Sr is looking down and smiling.
Alright everyone listen up. I ordered 2 of these bad boys and it is absolutely worth it. I haven’t been into R/C in years but these little dudes are amazing. Quality, fast delivery, what more could you ask for? The speed is amazing for its size, 50% is fun, 75% perfect speed and handling, 100% stupid fast about uncontrollable! Not gonna lie I love them so much I ordered 1 more to keep in the box or use for parts since who knows when extra batteries or stock will be available. LOSI hit an absolute HOME RUN with this one. Do your self a favor and order 2, not 1 but 2.!!
My son and I love these micros and the mini b and t as well. One had a transmitter throttle issue and can always count on Amain for their amazing customer service. Not worth even buying cars elsewhere with this level of service! It takes the stress out of broken cars completely. More stars are needed for Amain reviews. Keep it up guys! Thank you
Reviewers broadly praise the Micro-B's speed, indoor handling and fun factor for its size, with many describing it as a strong out-of-box performer and good value. Several note it slides on hardwood or Formica floors and performs best on carpet or rugs, with scrubbing tires helping grip. Recurring criticisms include shipping delays (several reviewers blame the seller's carrier), and a notable minority report electronics failures, including a battery or USB charger that melted or appeared unsafe, and a unit whose throttle stopped working. Some reviewers mention a battery connector that was hard to remove and a controller button fault that was replaced under warranty. One reviewer objects that the brushed motor is incompatible with the 15mm brushless motors common in the micro class. Reviews are mixed on reliability, with a clear split between satisfied owners and those reporting early failures.

- + Handles well indoors and on carpet
- + Good out-of-box performance
