RC Car Gasoline Losi BAJA 5B 29cc Engine – 1/5 Scale High-Performance Gas RC Buggy
Introduction to 1/5 Scale Gasoline RC Cars
If electric RC cars are the bicycles of the hobby world, 1/5 scale gasoline RC cars are the motorcycles. They’re loud, powerful, heavy, and insanely fun. Built for serious enthusiasts, these machines deliver raw mechanical realism that battery-powered models just can’t replicate.
The RC Car Gasoline Losi BAJA 5B 29cc Engine with Dual 48KG Servos sits proudly in this elite category.
What Is the Losi BAJA 5B Style 1/5 RC Car?
The BAJA 5B design is legendary in large-scale RC racing. Originally popularized by Losi, this buggy layout focuses on:
Rear-engine balance
Wide track stability
Extreme off-road durability
Modern versions like the DDT / 30°N BWS-5B take this DNA and refine it with upgraded materials, smarter aerodynamics, and stronger electronics.
Overview of the DDT / 30°N BWS-5B RC Gasoline Buggy
The BWS-5B is a 1/5 scale gasoline-powered RC buggy equipped with a 29cc 4-bolt engine, dual 48KG high-torque servos, and a 2.4GHz long-range radio system. It arrives Almost Ready to Run (ARR), meaning most heavy assembly is already done.
In short: it’s built to dominate dirt, gravel, sand, and open terrain.

29cc Gasoline Engine Performance
Engine Design and Cooling
The 29cc engine delivers massive torque, perfect for launching this heavy buggy across rough terrain. The forward-mounted pull starter improves airflow, helping the engine stay cooler even during aggressive driving.
Think of it like moving the radiator to the front of a race car—it just makes sense.
Speed and Torque Output
With proper tuning, this RC buggy can hit 80 km/h, which feels terrifyingly fast at ground level. Torque delivery is smooth, predictable, and powerful—ideal for both racing and bashing.
Dual 48KG High-Torque Servo System
Steering Servo Performance
A 1/5 scale RC car needs serious muscle. The 48KG steering servo ensures precise, confident control even at high speeds or when landing jumps.
Throttle and Brake Control
The second 48KG servo handles throttle and braking duties, delivering crisp response and reliable stopping power. With lithium batteries, torque can reach up to 62KG, which is just absurd—in the best way.
Chassis and Build Quality
6061-T6 Aluminum Chassis
The chassis is CNC-machined from 6061-T6 aluminum alloy, offering an ideal balance of strength and flexibility. It absorbs impacts instead of cracking—exactly what you want when things go sideways.
Shock System and Suspension
Adjustable front and rear hydraulic shocks
6061-T6 aluminum shock supports
This suspension setup eats bumps for breakfast and keeps the buggy planted at speed.
Aerodynamic and Structural Design Highlights
Aerodynamic Buggy Shell
The streamlined shell reduces wind resistance and increases grip. Dual front air inlets improve engine cooling and air filter intake efficiency.
Whale Tail Rear Wing
Inspired by real racing aerodynamics, the rear wing automatically adjusts its angle during high-speed driving, increasing downforce when it matters most.
Pig Nose Front Bumper
This uniquely shaped bumper absorbs frontal impacts, protecting critical components during crashes.
Golden Delta Protection Holder
A dual-material design:
Internal nylon: Engine protection
External elastic material: Shell support
Positioned at the highest point, it protects both the engine and shell during rollovers—essential for aggressive driving.
Cooling, Exhaust, and Airflow Engineering
Forward-Mounted Engine Layout
Placing the pull starter forward enhances airflow, reducing heat buildup around the engine and exhaust.
Silver Spirit Silenced Exhaust
Made from stainless steel and engineered by international designers, this exhaust delivers:
Deep, refined sound
Improved back pressure
Enhanced engine performance
Ventilation Guard and Air Filter
A side ventilation port creates negative pressure at speed, pulling hot air out automatically. The silenced air filter reduces intake noise—perfect for competition environments.
Driving Experience and Handling
Off-Road Stability
The wide wheel track (375mm front / 370mm rear) keeps the buggy stable over rough terrain. It feels planted, predictable, and confidence-inspiring.
High-Speed Control
At full throttle, the BWS-5B feels like a missile with manners. Steering remains responsive, and the suspension keeps everything under control.
Comparison with HPI, Rovan, KM, and Losi DBXL
Compared to competitors like HPI Baja, Rovan, KM, and even Losi DBXL, the BWS-5B offers:
Better value for money
Stronger standard servos
Enhanced aerodynamic features
It competes hard without demanding premium-brand pricing.
