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 Batteries:

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.

Questions and answers about Associated RC10B4.2RS 1/10 Electric Buggy RTR ASC9042

From Customer | 2017-06-03 03:44:14

would this car be able to race in stock competitions with no further changes?


This really depends on your track and the rules of your local track. It should be fine to race at most tracks in a stock class or if you're just starting out a novice class.

From Customer | 2017-04-23 19:51:41

Will the gearbox from this fit on my 1987 RC10.


Unfortunately it will not.

From Customer | 2016-08-03 10:43:00

Is it equipped with a 12mm hex?


It does come with the 12mm hex so you might be able to get these Pro-Line Sling Shot 2.2 1/16 Mounted Sand Tires E-Revo part number PRO1010110 to fit.

From Customer | 2016-08-03 09:35:23

What are some good tires for the sand?


Well, about the only ones we know of where the Pro-Lines # PRO10101-00 Sling Shot 2.2 Sand Tires (2) 1/10 Buggy Rear. Unfortunately, these have been discontinued and we do not see any others that would work unless you go with a 2.2 truck size like the Panther 2.2 Paddle Truck Tire Firm (2) part number PAHT470.

From Customer | 2016-03-26 11:05:57

What is a good after market motor to put on this buggy for top speed to increase?


If your just trying to do speed runs I would probably look at the SV3 Castle Creations 5700kv then run a 3s lipo pack.
