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

International Shipping Restriction Batteries:

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.

Don't forget to tighten slipper on Brushless E-maxx, Especially if running 6S!

So I got a brand new Brushless E-maxx with a dual 3s 5000mah battery set and was anxious for my first run. Like any normal person, I completely ignored the manual and warnings during the unboxing. The batteries were charged and I was ready to tear up my yard. My buddy warned me that I should break in the transmission before ripping it on full throttle, Again, like any normal person, I completely ignored his warnings. I drove it slowly for the first 10 minutes to get the hang of how the truck handles, then I figured that was enough of a break-in period and decided to unleash the beast! The raw power and torque of the truck were absolutely exhilarating... for about 5 minutes. For some reason the truck completely stopped moving, the motor roared, but the truck was stagnant. Naturally, I was very upset and prematurely started badmouthing Traxxas about how their overpriced products don't even last 30 minutes without breaking down. I took the truck inside and started to search for the root of the problem. I unscrewed the transmission case and found a completely mauled and melted spur gear. The slipper clutch got so hot that it melted a perfect circle in the center of the gear, and the pinion gear finished it off. This is when I decided to thoroughly read the manual to find out the cause of the damage. Apparently you have to break in the slipper clutch with a Ni-Cad or 4s power system, and tighten the slipper clutch after the break in period. Thankfully, I only broke the spur gear and I was relieved to find it on R/C planet for under 3 Bucks! I immediately ordered it and had my truck running again in under a week. Haven't had problem with this spur gear since! I hope my story has helped you in some way, Good Luck!
