Shipping Surcharge

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 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


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.

T-Rex 250 Pro DFC Features:
  • Extreme low CG and short main shaft design, dramatically reduces flight resistance, effectively improves T-Rex 450’s 3D performance and speed.
  • New style linkage rod design, complete assembly increases linkage rod rigidity, allowing the pitch slider (follower) to be omitted, resulting in a head assembly that is much simplified and rigid.
  • Designed specifically for DFC rotorhead system, improving DFC connecting rod’s strength and minimizing linkage detachment during extreme flight maneuvers.
  • Material integration technology used in frames, improving rigidity and simplifies maintenance.
  • New style quick removable gyroscope mounting platform integrated with rudder servo mount, effectively utilizes frame’s inner space for simplified maintenance.
  • New anti-rotation guide.
  • Strengthen landing skids enhanced its durability.
  • High efficiency shaft tail drive system, effectively increase rudder performance and decrease power loss.
  • Single unit tail belt unit with the new counter weighted tail blade grips make it easier assembly and improving rudder efficiency
  • Utilizes dual point attachment design for zero play and higher precision control feel
  • Streamlined design canopy

3GX Programmable Flybarless System Features:

  • 3GX is currently the smallest and lightest flybarless system available on the market. Two ports to directly connect Spektrum and JR satellite receivers, along with full support of Futaba's S-BUS system
  • Illustrated instructions on the computer setup software helps direct the user through a step by step setup process, allowing for quick setups without omitting any steps
  • With 3GX's built in Align RCE-G600 governor function, no external governor is needed to reduce electronic wire clutters
  • 3GX utilizes brand new gyroscope sensors of the highest specifications when compared to other flybarless systems currently on the market, allowing it to be used under harsh conditions. Dual axis plus rudder sensor dramatically improves swashplate and rudder correction precision compared to last generation 3G. This is clearly noticeable in stable hover as well as highly aerobatic routines
  • The superior vibration resistant characteristic is evident even when mounted with harder double sided mounting tape
  • 3GX utilizes 16 bit processor which is 4 times faster than previous generation, along with a completely re-written firmware. The result is a dramatic stability improvement from previous generation, with stability that rivals a flybarred helicopter, yet posses explosive agility
  • 3GX's rudder allows consistent rudder feel even under high speed conditions. This excellent control feel will allow pilot of all skill levels to experience the perfect integration between 3GX and helicopter.
  • Brand new redesigned 3GX represents a new generation of multi function flybarless system. The dramatically improved performance will create immediate impact on any enthusiasts.
  • Based on the 3G FL760 manual setup process, the 3GX can be setup in just a few minutes through a simple process. In addition, the 3GX can support all of the CCPM swashplate systems currently on the market including 90, 120, 135, and 140 degrees swashplates.
  • Supports Bluetooth connectivity- With the soon to be released Bluetooth connectivity kit, the 3GX can be programmed wirelessly from a PC. Eventually there will also be smartphone apps allowing live adjustments to 3GX without powering down.
  • Custom parameters have been opened up in 3GX to allow pilots to fine tune numerous settings for the swashplate and rudder. The settings export feature allows custom settings to be shared amongst friends.
  • Suitable for helicopters of all class from 250 to 800, glow engine or electric powered.
  • With built in pirouette compensation function, the 3GX is able to stabilize the helicopter on a fixed point during pirouetting maneuvers. Pirouetting flips type of maneuvers are easily accomplished with precision.
  • Support with APS gyro system and bring up more functions for your helicopter. With the APS gyro, the helicopter will have the ability to self stabilize, hold position as well as altitude, and even autonomous way point flights as well as return home.
