The World's Fastest
Mini-Monster Truck!

The Savage XS Flux packs in everything you know and love about the neck snapping, standing backflip-capable Savage Flux! A ridiculously powerful Flux brushless powerplant to provide you with the most menacing speed runs, legendary Savage durability that passes the bashing exam with flying colors, innovative TVP technology for a class leading design, and extreme monster truck appearance and ground clearance to conquer it all.

Oh, did we mention that it fits in your backpack? That's right, the compact Savage Flux XS goes where the standard size Savage can't. At 2/3 the size of a standard Savage, the Savage XS Flux is the perfect size for backyard tracks. The Savage XS Flux is built tough with an all-metal drivetrain so it can handle giant jumps and speeds over 65mph. The 4WD system provides excellent traction on any off-road or on-road surface you can throw at it. And it's all built with legendary Savage toughness so you spend more time driving and less time wrenching.

Pre-assembled from the factory, the Savage XS Flux is ready to go right out of the box, including a 2.4GHz radio system and Flux brushless system. Just add your favorite 2S Li-Po battery pack like the HPI #101941 or #101942 Plazma 7.4V batteries and start driving! If you want crazy performance and speed the Savage XS can also handle 3S Lipo power (see below for details)! 

The 65+ MPH Savage XS Flux - The World's Fastest Mini Monster Truck. PERIOD.

Easy to Drive!

The Savage XS Flux is super-easy to drive and get familiar with – to drive the truck, simply pick up the controller with your left hand, put your left index finger into the trigger area, and then put your right hand on the steering wheel – it’s as natural as driving a real car! Turn the wheel to go left and right and gently pull on the trigger with your left index finger to go forwards. To brake the truck and come to a stop, gently push away from you with your left index finger. It takes just seconds to get used to driving an RC car, and soon you'll be doing speed runs, power drifts and huge jumps with ease!

Waterproof Protection

The Savage XS Flux features waterproof protection for its electronics and it's ready to tackle wet conditions like rain and snow! The 2.4GHz receiver is safely stored in a waterproof receiver box, protecting it from the elements and ensuring glitch-free operation. The waterproof SF-10W steering servo and waterproof Vapor Pro electronic speed controller complete the package, allowing you to enjoy the action on the road no matter what the weather is like! Please note: the electronics are not designed for submerged operation. Be sure to rinse off any dirt or salt water with clean water immediately after driving. Check the receiver box to make sure no water is inside and let dry fully before driving again. 


Tough "Savage style" TVP Chassis

The chassis for the Savage XS Flux is very similar to the nitro-powered Savage that we all know and love - the backbone consists of the TVP (Twin Vertical Plate) design, formed from two 5mm chassis plates, with the diff cases at either end providing significant stiffness and the transmission casing and motor plate forming load-bearing members of the structure.

LiPo Battery Power

The Savage Flux XS is designed to use 2S or 3S LiPo packs. The battery box features vents to keep the battery pack cool, and we suggest using an official Deans® zero-loss battery plug to match the plug on the ESC. Out of the box, the Savage XS Flux is optimized for 2S Lipo Power. 2S gives the best balance of handling and performance. Standing backflips? No problem! But if you want to go for crazy top speed or simply brutal power upgrade to 3S LiPo batteries like the #101943 Plazma 11.1V 3800mAh! However, be aware with that much power you've got to know what you are doing! Depending on what you want to do and where you want to run the car you will have to adjust the gear ratio. Option parts #105809 & #6924 are required for 3S running in most situations like going off-road or doing stunt driving. 


All-metal Transmission Gears

The Savage XS Flux features all-metal transmission gears to make sure that power delivery is uninterrupted and every jolt of power gets from the motor to the tires efficiently and with no worry of damage to the gears. The whole drivetrain runs on ball bearings for optimal efficiency, extra-long runtimes and mega-fast top speeds!

Ultra Tough Over-sized Suspension

The over-sized suspension design makes the Savage XS extremely tough and capable of handling even the wildest bashing action. Aluminum 12mm hex hubs allow the mounting of almost all standard 1/10th scale wheels. 


Silicone Filled Threaded Shocks

Four threaded shocks give the suspension action you need to get out and blast through the roughest of tracks or off-road terrain. Filled with silicone oil, the slick nylon bodies are lightweight and strong, with almost no 'stiction' between the shock piston and shock body for smooth and consistent damping.

All-Terrain Tires, 1/10th compatible

With the aggressive tread of the 2.2" GT2 tires, you can go off-road to on-road with predictable handling. The center tread lines give you stability on paved surfaces while the blocky tread pattern and heavy-duty sidewall teeth provide grip for off-road terrain like dirt, mud, muck, leaves. They're mounted on black chrome 2.2" Warlock wheels for tough monster truck styling. For maximum hop-up potential, the Savage XS Flux accepts a wide variety of 1/10th scale 2.2" wheels and tires, making customizing your truck easy. 


Flux VEKTOR 4000 Motor

The Flux VEKTOR 4000 motor delivers massive power - plenty of juice for instant wheelies and standing backflips! Option pinion gears are available to fine-tune the speed and torque delivery! The brushless design assures maximum performance with nearly no maintenance required.


With the capacity to handle 2S and 3S LiPo power, the Flux VAPOR Pro electronic speed control can take anything you can possibly throw at it and keep coming back for more! The VAPOR Pro features an integrated cooling fan to keep it cool in tough conditions. The Flux VAPOR Pro ESC is reversible so you can back out of jams with ease. And for maximum adjustability it's fully programmable with our optional #100573 USB Programming Kit..
