Losi have introduced the new Tenacity SCT RTR 1/10 4WD Short Course truck. The world-famous TEN platform is now more accessible and affordable than ever—with easy-to-use features and Spektrum AVC control. The Tenacity is tough, durable and fast and built on the original TEN platform. Now Losi is bringing the TEN to the masses with easy-to-use features and Spektrum AVC technology (including the option of telemetry). The Tenacity borrows some of its design from the TEN MT, such as the bottom-loading battery configuration for simple and quick battery changes.

Legendary TEN 4WD Platform

Based on the TEN MT, the Tenacity is a durable, high-performing short course truck with a racing pedigree. Its tough composite chassis helps lower the weight and you won’t believe how easy battery changes are with the bottom-load battery door.

Dynamite 130A Brushless ESC and Fuze 4-Pole 3800Kv 550 Motor

The Tenacity’s brushless ESC and 3800Kv motor provide incredible power with a 2-3 cell LiPo (not included). The Dynamite Fuze 130A ESC is the newest addition to the Fuze ESC lineup. It’s waterproof, completely programmable and comes pre-wired with a high-current EC3 connector. The ESC works with most sensorless brushless motors and is Ni-MH and 2S and 3S LiPo compatible—allowing you to run at speeds of 50 MPH or more.

Waterproof Components

To provide you with added flexibility, all the Tenacity’s components are waterproof so you can run in wet conditions, pretty much wherever and however you want. No more shying away from puddles—now you can rip across them whenever you want.

12mm Race-Inspired Plastic-Bodied Shock Absorbers

These shock absorbers help keep the Tenacity incredibly stable and so you can maintain control on even the toughest terrain.

MAXXIS Razr MT Tyres

Working together with MAXXIS Tyres, Losi added scaled-down Razr MT tyres with an aggressive tread pattern that will help you tackle any terrain. Whether you’re driving on asphalt or dirt, these tough tires provide long-lasting tread life and world-class performance.

Race-Inspired Scale Body

The Tenacity’s scale, race-inspired short course body features sleek graphics in two different color variations, black or yellow.

Spektrum DX2E Radio System

The Spektrum DX2E transmitter gives you the control you need to take on obstacles in your backyard or at the local track. Its proven performance, reliability and range are trusted by RC enthusiasts around the world. The Tenacity also comes with the new SPMSRS6000 Spektrum receiver with steering priority, so you’ll no longer under-steer when the AVC dial is turned on.

Speedometer Option

Adding telemetry (not included) to the Spektrum DX2E is easy—all you need is the optional add-on Bluetooth speedometer module. This module gives you access to a full suite of programing and telemetry through the new DX2e Raceware app. The speedometer’s three-position throttle and steering limiter switches will help beginners progress from slow to full speed.

The Full-Throttle Freedom of AVC Technology

When you’re ready to let the brushless motor off the chain, don’t hold back. The receiver’s built-in AVC (Active Vehicle Control) system will work behind the scenes, making hundreds of tiny throttle and steering adjustments per second, so more of the motor’s power is translated into ballistic speed and acceleration instead of just flying dirt. An AVC adjustment knob on the included DX2E transmitter lets you adjust how much traction control the system provides. You can even turn it off.
