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.

Rocket Motors, Rocket Igniters and Rockets are classified as Toy Propellant Devices and can only be transported through Surface Mail with the US Postal Services Parcel Post. FedEx does not transport Rocket Motors, Rocket Igniters and Rockets. Please note that FedEx will not show up as a delivery option during checkout.

International Shipping Restriction

However, RC Planet can ship batteries internationally using DHL International, but the quantity cannot exceed a total of 2 batteries with a capacity of 5000mah maximum. Unfortunately we are currently unable to ship this item to APO/FPO addresses and apologize for the inconvenience.

I have owned and used HPI products for many years now, and the WR8 is definitely one of their best vehicles, if not THE best. My only complaint is that they didn't carry over the TF-40 transmitter from the older version. I've already ordered that. In my opinion this car is amazing.

"Alexey Parfenov"

"very fast car"

"Stock tires are very sticky, sometimes it even throws over in turns.Handles nicely."

"Jake Lange"

"Needs to be Stronger"

"Body posts broke off from the first roll and tires were shredded after about 6 batterys. Not Impressed, still waiting for replacements."

From Customer | 2015-07-11 02:47:52

Is there a list of updates from this 2013 model?

I bought the original (green) one back in 2012 I believe. Other than the body, were there any upgrades/improvements to the car I should know about which will affect performance?


We haven't received a list of upgrades for that model. The only thing that I would upgrade would be the battery. I would go with a 7.4v lipo battery and that will help out with the speed of the car.
