The Losi® LST 3XL-E is the one you’ve been waiting for: a monster truck that can handle wild abuse and wicked speeds of up to 50+ MPH*. You’ll love the raw power and control that comes with a Spektrum DX2E ACTIVE with AVC control.

At a Glance

Are you ready for this? More speed, more power, extreme durability—the Losi® LST 3XL-E takes the LST platform to the next level. Hit the terrain at speeds of up to 50+ MPH* on 6S power. Whether you’re on dirt or pavement, this basher will not disappoint. You’ll have control at all times thanks to the AVC® system. And when it comes to taking abuse, the 3XL-E doesn’t flinch—this isn’t a monster truck that gets intimidated easily. Bottom line, if you loved the LST XXL-2 E, you will be obsessed with the 3XL-E.

*50+ mph speeds can be achieved with optional gearing. 

Chassis and Side Rails 
Low center of gravity molded chassis lowers the batteries to provide increased durability, stability and performance.

LSD Center Differential
Unlike most monster trucks, the 3XL-E uses a center differential that ensures a proportional delivery of power to all parts of the vehicle, regardless of conditions. It lets the truck accelerate and stay balanced on any terrain.

Updated Center Drive Shafts
A spring retaining coupler helps keep the drive pin in place.

Large Scale Servo
The Spektrum S904 1/6 Scale WP Digital Servo is a larger, stronger servo for worry-free steering performance. 

Servo Saver
The adjustable servo saver is designed to work with large-scale servos.

Flip Top Body Mount
Removable flip top body mount provides easy access for battery changes and maintenance.

Speedometer Option
The Spektrum DX2E ACTIVE with telemetry lets you measure actual speed via an optional speedometer that plugs into the DX2E ACTIVE.

Spektrum DX2E ACTIVE radio system with AVC
Reliable Spektrum radio and the security of Active Vehicle Control. Truck includes new SPMSRS6000 receiver with steering priority. You’ll never under steer when AVC is activated.

Dynamite Electronics
The Dynamite Fuze 150A Brushless ESC and Fuze 1/8 Brushless 2200Kv Motor run on 4S or 6S power, providing speeds of up to 50+ MPH. New integrated motor cool fins provide cool temps for longer run times and enhanced performance.
