LOSI TENACITY TT PRO BRENTHEL 1/10 3S 4WD BRUSHLESS DESERT TRUCK RTR

THE TEN PLATFORM, 3S BRUSHLESS POWER AND TROPHY-TRUCK CONTROL.

The Losi TENACITY TT Pro Brenthel 1/10 3S 4WD Brushless Desert Truck RTR combines the proven TEN competition-based chassis with a Spektrum Smart power system, AVC stability control and officially licensed Brenthel, Method and Falken details. It is built for high-speed dirt running, rough short-course terrain and hard backyard use without reducing the chassis to entry-level plastic hardware.

On a suitable 3S LiPo, Losi rates the 3150Kv system for 50+ mph. Battery and charger are sold separately, allowing the owner to choose a quality 2S setup for easier control or a 3S setup for maximum performance.

LEGENDARY TEN 4WD PLATFORM

The truck is built on a 4 mm 6061-T6 aluminum plate chassis, a serious structural foundation that resists flex under acceleration, landing and cornering loads. Full metric hardware, aluminum shock towers and standard adjustment points make the TT Pro a serviceable hobby-grade machine rather than a sealed disposable RTR.

The layout centralizes the motor, ESC, steering system and battery to balance the chassis. A full set of ball bearings supports the driveline for smoother operation and reduced rotating friction.

FULL-TIME 4WD WITH THREE TUNABLE DIFFERENTIALS

Power is distributed through front, center and rear sealed gear differentials. The spiral-cut bevel gears are filled with silicone fluid and can be tuned with different fluid weights to change steering, rotation and power delivery. The center differential helps absorb driveline shock and divides torque between the front and rear axles, producing more controlled handling than a rigid center spool at high speed.

3150KV 550 BRUSHLESS MOTOR

The Spektrum Firma four-pole 3150Kv 550-size sensorless brushless motor supplies the torque required to accelerate a 2.72 kg trophy truck through dirt and loose terrain. With an appropriate 3S LiPo, gearing, surface and conditions, the platform is rated for speeds above 50 mph. On 2S it remains fast but more manageable, with reduced heat and longer practical control windows.

SPEKTRUM SMART 130A ESC

The programmable Spektrum Smart 130A brushless ESC is compatible with 2S–3S LiPo power, uses a high-current IC5 connector and supports Smart telemetry when paired with compatible Spektrum equipment. Its generous current capacity is matched to the heavy 1/10 truck and 550 motor.

The onboard electronics are designed for wet-condition use, but water resistance is not permission to treat the truck like a submarine. After damp operation, clean and dry the chassis, bearings and hardware promptly.

INDEPENDENT SUSPENSION AND 12MM ALUMINUM SHOCKS

Independent suspension at all four corners lets each wheel react to bumps without forcing the opposite side to follow. The 12 mm aluminum-bodied oil-filled coil-over shocks use threaded preload adjustment to set ride height and spring preload. Shock oil and spring changes provide additional tuning for track grip, jump landings or rough desert-style terrain.

Four-millimeter 6061-T6 aluminum shock towers support the upper mounts. Their strength matters when the truck lands off-axis or strikes repeated chop at speed.

ADJUSTABLE TURNBUCKLES AND SWAY BARS

Adjustable turnbuckles permit alignment changes instead of locking the owner into fixed factory geometry. Camber and toe can be corrected after service or tuned to suit the surface. Front and rear sway bars control chassis roll during fast transitions; their adjustment lets the driver change the balance between steering response and rear stability.

DX3 RADIO AND AVC STABILITY CONTROL

The Spektrum DX3 transmitter works with an AVC receiver that makes rapid steering and throttle corrections when the vehicle begins to slide or wander. AVC does not drive the truck for you; it helps translate motor power into forward motion while preserving normal steering control. Assistance can be adjusted or disabled to match driver preference and surface conditions.

The DX3 also provides a three-position throttle limiter and travel adjustment. With compatible Smart batteries, the radio system can display useful battery-voltage status through its indicator.

LICENSED BRENTHEL, METHOD AND FALKEN DETAILS

The race-inspired body is officially licensed by Brenthel and reproduces the broad fenders, cab shape and rear cage treatment of a full-size trophy truck. Licensed Method wheels and Falken Wildpeak MT tires complete the scale package. The medium-soft Wildpeak tread is intended to work across dirt, gravel and pavement rather than only one prepared racing surface.

METAL-GEAR STEERING AND FUNCTIONAL LED BAR

A waterproof metal-gear steering servo handles the loads generated by the 297 mm-wide truck and its off-road tires. A functional front LED light bar improves visibility at dusk and reinforces the desert-race appearance. Night driving still requires a clear, safe area; the light bar is not a substitute for seeing obstacles beyond the truck.

DETAILED SPECIFICATIONS

• Spektrum DX3 radio system
• Spektrum AVC receiver
• Spektrum Smart 130A brushless ESC
• Spektrum Firma 3150Kv 550 brushless motor
• Installed metal-gear steering servo
• Four AA transmitter batteries
• User manual

NEEDED TO COMPLETE

• One 2S or 3S hardcase LiPo battery; approximately 5000mAh and 30C or higher recommended
• IC5 or EC5 battery connector
• Compatible balance charger
• LiPo charging / safety bag

GASHEAD RC SETUP NOTES

• Begin with 2S or reduced throttle while learning the truck; 50+ mph performance requires space, visibility and experience.
• Set steering endpoints before hard use so the servo is not forced against the mechanical stops.
• Inspect wheel nuts, hinge pins, shock hardware, driveshafts and differential cases after high-speed or jump sessions.
• Monitor motor and ESC temperature when gearing, tire size or ambient temperature changes.
• AVC is an aid, not a substitute for correct suspension setup, tires or throttle control.
• After wet running, dry the truck and service metal components. Water-resistant electronics do not make bearings and hardware maintenance-free.

GASHEAD RC VERDICT: A serious 1/10 trophy truck with the aluminum TEN platform and adjustment range to satisfy experienced drivers, while AVC and 2S compatibility make the performance easier to approach responsibly.
