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.

This is the Kyosho Ultima RB6 2WD Competition Buggy.

The Ultima RB6’s features a hard-anodized high-tech chassis that’s built from 7075"aluminum. With kickup at the front and angled side trays, this chassis mirrors the chassis of the RB6, the technology of the 1/8-off counterparts in 1/10 scale again. With an additional length of 13mm, the chassis supports the modelnd leads to an increase in stability.

The all-new Ultima RB6’s gearbox unit was designed to be especially small and convenient. This allows the engine and transmission to be placed very low on the chassis, making the overall center of gravity of the modeldeal. The transmission is in the rear-engine and a three-tier takes the force of the ball differential to the rear wheels. The ball differential is easily adjustable from the outside, the set points come protected by with dust covers.

The entire rear axle on the Kyosho Ultima RB6 is symmetrical, resulting in lower maintenance costs. The track and caster angle can be changed by varying the mounting arm shots. The upper arms come equipped with R / L-threaded rods and pivoted on ball heads. Utilizing spacers, the angle of the upper wishbone can be changed. Power is efficiently transmitted to the rear wheels via propeller shafts, which shine with their perfect finish. The use of upward angled wishbones gives you a more agile steering response, and high stability is achieved on the ground.

The front axle on the Ultima RB6 is symmetrical and has long and narrow wings, making the entire front axle compact and light. The bearings on the front wheels are special low-friction ball bearings that are equipped with a fiberglass plate, which effectively seals against dust and other small debris. All parameters such as track, camber and caster can be adjusted with little to no effort.

The battery layout of the Kyosho Ultima RB6’s chassis is used both in the rear-engine configuration and in the mid-engine configuration. The chassis gives you the possibility of using stick batteries, saddle-packs or shorties; no matter what engine configuration is in use.

The all new and ball-bearing steering geometry is constructed of black anodized aluminum and is the same angle as the front control arm, forming the Ackermann effect over the entire steering range. Kyosho has utilized deflection elements made of aluminum; the steering is precise even in the toughest of conditions.

The shock towers on the Ultima RB6 are made from a special synthetic fibrous material. This material has the requisite hardness needed for racing, but also has the necessary flexibility in the event of a hard crash. Both shock towers have a varierty of mounting points in every possible route tune.

The Kyosho Ultima RB6 sports “Triple” BigBore oil shocks with three main components: the upper shock cap, the damper housing and the lower damper cap.
