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 Motors, Rocket Igniters and Rockets are classified as “Toy Propellant Devices” and can only be transported through Surface Mail with the US Postal Service’s 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


Due to circumstances and regulations that are beyond RC Planet's control, batteries cannot ship outside of the US when using the United States Postal Service as the shipping provider. 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.


Due to distributor restrictions, the following brands are not available for sale outside of the 50 United States: Losi, Team Losi Racing, Blade, ParkZone, ECX, Hobby Zone, E-Flite, Vaterra, Dynamite, Pro Boat, Spektrum, JR Radio, Orion, and Hangar 9.

RC racers are constantly looking for the next big thing and the very best parts to put on their vehicles to give them an advantage over the competition. Pro-Line’s goal is to constantly push the limits of technology and bring their customers the very best with each new product. After months of research, development and testing, Pro-Line has produced the Best Performing and Ultimate High-End Racing Shock Shaft ever produced: Pro-Line’s Black Diamond Series for 1/10th scale Off-Road Racing Buggies.

Pro-Line started with the highest grade USA forged Ultra Alloy Material and then Precision Centerless Ground and machined the shafts to absolute tolerances and finish specifications using CNC machines (proudly in the USA).

Then Pro-Line roll formed the threads instead of cutting in the threads for the highest strength threads possible. Pro-Line didn’t stop there and found the highest grade shaft coating currently known to mankind – Black Diamond DLC coating. This is the exact same coating found in Formula 1, NASCAR and Factory MX Bikes on suspension components, engine components and anything that requires virtually zero friction and ultimate durability.

Diamond-Like Carbon DLC coating creates a much harder surface than standard TiNitride shaft coatings and delivers a 10 times smaller Coefficient of Friction for the smoothest shock action that has ever been achieved in the history of RC. Pro-Line is changing the game and delivering Next Generation Shock Shaft Technology all proudly made in the USA! Get yours today!
