If you can dish it out, the Losi TENACITY short course truck can take it. This basher is built on the original TEN platform—known worldwide as one of the toughest platforms around. 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. But it also adds a spin on the TEN platform with a Dynamite 130A brushless ESC and Fuze 4-pole 3800Kv 550 motor that lets you tear up the terrain at speeds of 50 MPH or more with 3S power.


In-Depth Features: 

  • Legendary TEN 4WD Platform: Based on the world-famous 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 Tires: Working together with MAXXIS Tires, Losi added scaled-down Razr MT tires 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.
  • 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.

Losi Tenacity SCT RTR 1/10 4WD Brushless Short Course Truck (Black/Yellow)
My first RTR and first RC in over 20 years. Very powerful motor and extremely fast. Difficult to roll given the speed, decent suspension keeps it on the wheel side. One shock broke afte about 20 hours. Plastic part and I was very rough on it. Torque is moderate, but more than sufficient to get it up to speed quickly. Overall very fun car.
