Ground Shipping Items

Some RC Planet's products can only be transported under ORM-D (Other Regulated Materials for Domestic transport). Shipping under ORM-D means that the product will ship via FedEx Ground only, and cannot be shipped outside of the US. These products include:

  • Non-Water Based Paint and Paint Thinner
  • Petroleum-Based Oil
  • Aerosol Type Products
  • Traction Compounds
  • Tire and Body Cleaners
  • Epoxy / Accelerators / Debonder

The US Postal Service will not transport ORM-D items, and will not show up as a delivery option during checkout.


For All Shipments: Special labeling requirements are needed to safely transport any Lithium products. Certain large Lithium Batteries will always require HazMat handling and will only ship via Fedex. If you would like to know more about FedEx and the safety precautions taken when transporting Lithium Batteries, please refer to the FedEx guidelines.

International Shipments: Lithium Batteries are regulated as HAZMAT (Hazardous Material) products and can be dangerous if not packaged properly for transportation. In smaller quantities, Lithium Batteries can be shipped via DHL without applying a HAZMAT fee. If you'd like to ship more than 2 Lithium Batteries, a HAZMAT fee will be applied for transportation. Please note that DHL only allows transportation of HAZMAT / Dangerous Goods to specific countries, some of which have limited service areas.

The US Postal Service prohibits international mailing of Lithium Batteries, as well as electronic devices that contain Lithium Batteries. These new regulations also prohibit shipments to or from Army, Fleet, and Diplomatic Post Offices. Because of these regulations, no US Postal Service shipping options will be available during checkout.

Domestic Shipments: Both FedEx and the US Postal Service are available as shipping carriers for most Lithium Batteries and electronic devices containing Lithium Batteries. Please note that the US Postal Service has a limit of three batteries per shipment; you can refer to the Domestic Mail Manual for further information.


Fuel is classified as a "flammable" liquid. RC Planet can transport limited quantities of flammable liquid under ORM-D (Other Regulated Materials for Domestic transport). Shipping under ORM-D means that the product will ship via FedEx Ground only. For larger quantities of fuel (Example: case quantities), it must be transported under HAZMAT. Transporting as HAZMAT means that the amount of fuel is considered hazardous and will be subject to shipping by Ground services, including a HAZMAT fee for the special transportation. Fuel cannot ship outside of the US.

Please note that the US Postal Service does not transport Fuel and will not show up as a delivery option during checkout.

  • 2.4GHZ Radio System: The 2.4 GHz pistol grip features adjustments for steering trim, throttle trim, steering dual rate, servo reversing switches and low battery indicator.
  • Waterproof Electronics: The HPI Savage XS Flux has a waterproof receiver box to keep the 2.4GHz receiver protected from the elements for glitch-free operation. A new SF-10W waterproof steering servo and a waterproof VAPOR Pro electronic speed control mean your Savage XS Flux won't be stopped by wet conditions.
  • 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.
  • Flux VAPOR Pro ESC: 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 integrated cooling fans to keep it cooler 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.
  • LiPo Battery Power: The HPI Savage XS Flux 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.
  • All-Metal Transmission Gears: The HPI 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!
  • All-Terrain Tires: 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.
  • Compatibility: For maximum hop-up potential, the HPI Savage XS Flux accepts a wide variety of 1/10th scale 2.2" wheels and tires, along with standard 1/10th scale servos, batteries, receivers and electronic speed controllers.

"Out of the Box"

"This truck is a rocket ship!! But it does have some flaws i feel. Right off the bat the steering servo is very weak. It barely moves the tires. The radio system is extremely cheap, and the tires are not very good on loose dirt or grass. I am putting in a savox servo and an spectrum radio system . Also check the fail safe as mine was not on(they claim to be on from factory), if it looses single it will take of on you. Again part of the cheap radio system. The truck itself though is an awsome machine. Just be ready to make some upgrades right away. Not a recommended vehicle for someone new to R/C."

Q&A (7)

From Customer | 2016-07-15 18:52:26

How fast does this truck go out of the box?


This depends on what battery pack you purchase for it. On a 2s pack it will do about 40 to 45 and then with a 3s pack it can do up to 65 MPH.

From Customer | 2016-07-13 09:44:50

How would I find out how to adjust the wheel alignment on a Savage XS Flux?


It looks like stock out of the box these are not adjustable but you can upgrade with these part numbers HPI108074 and HPI106732 the you can adjust the toe in/ out and then your camber positive/ negative.

From Customer | 2016-04-27 07:55:11

What can I do to get the most power out of it?


Well going to a 3s LiPo will be the best way to unleash all its power. We think the 3s could be overkill, its plenty fast and fun with the 2s.

From Customer | 2016-04-26 08:05:14

What's the difference in speed from the brushless version to this version? Will this one still do massive wheelies and back flips like the original savage or do I have to go brushless?


This XS is brushless and does have plenty of speed its just an overall smaller truck. It does handle huge jumps and is capable of plenty of wheelie action.

From Customer | 2016-02-24 14:17:22

Does this truck have a fail safe? If i was to run the truck until i was out of the transmitters distance, would the truck automatically stop?


The included transmitter and receiver does have a built in fail safe.
