When Losi introduced the legendary 5IVE-T in 2011, it completely redefined what enthusiasts could expect from a large-scale RC truck. Combining the proven engineering philosophy of the championship-winning 1/8-scale 8IGHT platform with the size, presence, and performance of a 1/5-scale machine, the 5IVE-T quickly became a benchmark in the large-scale RC world.
More than a decade later, Losi raises the bar once again with the all-new 5IVE-TG 3.0.
At Aerobertics, we love RC models that combine serious engineering with pure driving excitement — and the new 5IVE-TG 3.0 delivers exactly that. This is not simply an evolution of the 5IVE-T platform; it is a completely reworked large-scale desert truck designed to deliver more power, greater durability, improved stability, and an even more impressive driving experience.
Fujiwara FJ350RC 35.2cc — More Power Where It Matters
At the heart of the 5IVE-TG 3.0 is the all-new Fujiwara FJ350RC 35.2cc gasoline engine.
Based on the legendary Zenoah G320 architecture, this engine features a larger bore that increases displacement and delivers significantly more torque and power. The real advantage is felt in the low and midrange, where the FJ350RC delivers stronger acceleration, improved response, and relentless pulling power.
Whether you're blasting across a dirt track, attacking rough terrain, or simply enjoying the sheer presence of a 1/5-scale gas truck, the FJ350RC brings the performance to match.
Pro-Line Mirage TT Tires & Licensed KMC Wheels
The 5IVE-TG 3.0 gets an aggressive new look thanks to its officially licensed KMC KM549 wheels, combined with massive 8.5-inch Pro-Line Mirage TT tires.
The innovative Pro-Line Pro-Loc bead-lock system makes tire maintenance easier than ever. When your tires eventually wear out, you can replace the tires themselves rather than having to replace complete wheel-and-tire assemblies — a practical solution that can save money over the life of the truck.
The Mirage TT tires feature an aggressive desert-style tread pattern and reinforced sidewall ribs, providing excellent support, stability, and control across a wide variety of terrain.
Six-Piece Injection-Molded Polypropylene Body
Losi has completely rethought the body of the 5IVE-TG 3.0.
Instead of a conventional polycarbonate shell, the truck features a six-piece injection-molded polypropylene body. This is the same type of highly durable material used on other demanding Losi platforms, including the Promoto-MX and Sprint Car.
The panels are designed to flex during impacts, absorb abuse, and maintain consistent material thickness throughout the body. The result is a body that is better suited to the realities of large-scale off-road driving — while individual damaged panels can be replaced more easily and affordably.
Longer Wheelbase. Greater Stability.
The 5IVE-TG 3.0 features a 26-inch / 660 mm wheelbase, giving this already massive truck an even more imposing stance.
The longer wheelbase isn't just about scale appearance. It also significantly improves straight-line stability at high speed, giving the truck a more planted and predictable feel when you're really pushing it.
Heavy-Duty Drivetrain & Optimized Gearing
The increased engine performance and larger tire diameter required a stronger and more efficient drivetrain.
Losi has redesigned the gearing around a new 43/12 ring and pinion combination with a 67-tooth spur gear, resulting in optimized acceleration and power delivery.
The drivetrain has also been engineered for improved strength, efficiency, and driveshaft durability, ensuring the 5IVE-TG 3.0 can handle the additional torque generated by the 35.2cc engine.
New 32mm Big-Bore Shocks
Large-scale performance demands serious suspension — and the 5IVE-TG 3.0 delivers.
The truck features new 32mm big-bore oil-filled shocks, providing increased oil volume for improved damping and more consistent suspension performance under the considerable weight and forces generated by this machine.
The new tapered shock pistons increase pack while delivering a more controlled and faster rebound, helping maintain traction and stability over rough terrain.
Losi has also redesigned the front and rear suspension arms, adding material around the shock mounting areas for improved durability and more uniform construction. Revised shock geometry further optimizes the shock angle between the towers and suspension arms.
Easy-Access Center Differential
Maintenance is a major consideration with any large-scale RC — and Losi has made servicing the 5IVE-TG 3.0 significantly easier.
The new easy-access center differential mount allows you to access the center differential simply by removing the center top plate, without having to disturb the brakes or linkage.
Less disassembly means less time in the workshop and more time driving.
Massive 1,000 oz/in Spektrum Steering Servo
Controlling a machine of this size requires serious steering authority.
The 5IVE-TG 3.0 comes equipped with a Spektrum SPMSS1000MT metal-top large-scale steering servo, delivering an impressive 1,000 oz/in of torque at 7.4V.
Its metal top case keeps the internal gears precisely aligned while also acting as a heatsink to help dissipate heat from the motor. The result is improved durability, consistency, and steering performance.
A matching Spektrum SPMSS1000 1/5-scale high-torque servo handles throttle and brake duties.
Spektrum Smart Radio System
The 5IVE-TG 3.0 arrives ready to run with a Spektrum DX3 Smart DSMR transmitter and SR615 DSMR receiver.
When combined with the included Spektrum 4000mAh 2S Smart LiPo receiver battery, the system provides Smart telemetry functionality, including real-time receiver battery information on the transmitter.
It's a straightforward and reliable radio package that works equally well for newcomers and experienced large-scale enthusiasts.
Ready to Run — Just Add Fuel
The Losi 5IVE-TG 3.0 comes almost completely ready for action.
Simply add:
91-octane gasoline or higher
High-quality synthetic 2-stroke oil
A suitable fuel mixing container
A ratio cup for accurately measuring the oil/fuel mixture
Install the included receiver battery, perform your pre-run checks, fuel the engine, and you're ready to experience one of the most capable large-scale gas trucks Losi has ever produced.
