How does the sensored brushless system improve racing performance?
The Losi C-LOS04020 with 2250Kv motor and sensored ESC features a Spektrum Firma 130A ESC paired with a 2250Kv motor, enabling seamless communication between components for ultra-smooth power delivery. Unlike sensorless systems that may stutter or cog at low speeds, this sensored setup ensures consistent throttle response from a standstill through the entire power band. This precision is critical for navigating technical track sections, executing controlled launches, and maintaining momentum through elevation changes. The sensored system also enhances braking modulation, giving racers the confidence to push harder into corners without sacrificing control.
What makes the aluminium chassis race-ready?
The 4mm thick aluminium chassis of the Losi racing truggy with aluminium chassis and oil-filled shocks provides a rigid and stable foundation for high-speed racing. Its extended wheelbase and wide stance contribute to improved balance and cornering stability, especially on rough terrain and during long mains. The chassis layout supports quick differential access for trackside tuning, while the integrated adjustable wing mount allows racers to fine-tune downforce based on surface conditions. Combined with aluminium shock towers and sway bars, the chassis architecture ensures the Losi C-LOS04020 4WD sensored truggy remains composed under pressure and adaptable to evolving track dynamics.
How do the oil-filled shocks and sway bars enhance handling?
The suspension system of the Losi RC car with S665 servo and sealed differentials is built around aluminium oil-filled shocks pre-filled with 4,545 WT fluid. These threaded shocks allow for easy ride height adjustments and can be tuned with different springs and oils to match track conditions. Front and rear sway bars are standard, helping to keep the chassis level through corners and reducing body roll during aggressive maneuvers. This combination of damping and roll control ensures that the Losi C-LOS04020 brushless racing truggy maintains traction and responsiveness, even on uneven surfaces and during high-speed transitions.
Why is the full metal driveline critical for durability?
The driveline of the Losi C-LOS04020 1/8 scale electric RC car is constructed entirely from heat-treated steel, including the axles, ring and pinion gears, and center spur gear. This robust setup is designed to withstand the torque demands of 4S power and the rigors of competitive racing. Fluid-filled sealed differentials allow each tire to drive independently, maximizing traction and reducing drivetrain stress. The gear pitch is Mod-1, and the internal gear ratio of 4.30 ensures efficient power transfer. With a final gear ratio of 13.19 and a 15T pinion, the driveline delivers consistent acceleration and top-end speed without compromising reliability.
What makes the electronics package suitable for all skill levels?
The electronics suite in the Losi C-LOS04020 4WD sensored truggy includes the Spektrum DX3 Smart transmitter, SR315 receiver, and S665 waterproof steering servo. The DX3 offers throttle limiting at 50% or 75%, allowing new racers to build confidence before unlocking full speed. Its Smart battery level indicator provides real-time telemetry, helping drivers manage power usage during long mains. The SR315 receiver supports forward programming, enabling advanced tuning when paired with compatible transmitters. The S665 servo features metal gears, over 270 oz-in of torque, and a fast 0.10-second transit time, ensuring precise steering response in high-pressure race scenarios.
How do Pro-Line OE components elevate race performance?
The Losi C-LOS04020 truggy with race-legal electronics and Pro-Line tyres includes OE-spec Axis body, Blockade tires, and Velocity wheels from Pro-Line Racing. These components are used in top-tier competition and provide aerodynamic efficiency, consistent grip, and structural integrity. The cab-forward body design enhances steering input and downforce, while the Blockade tires offer reliable traction across loose dirt, clay, and mixed surfaces. Velocity wheels are engineered for balance and durability, supporting high-speed stability and cornering precision. These race-proven elements ensure that the Losi C-LOS04020 brushless racing truggy performs at a professional level from the first lap.
