Where do you ship your RC Construction Models?

When you place an order with us, we will ship from the nearest warehouse to your location to ensure faster delivery.
For our hydraulic models, since many are not pre-made and require assembly, we ship directly from our stocking warehouse in China after thorough testing. It's important to note that some hydraulic models, such as the Kabolite 961 RC Excavator and Kabolite 966 Wheel Loader, are pre-assembled and often available in our overseas warehouses as well.
Please note that due to Brexit, we are unable to ship from our European warehouse to the UK.
Customers located outside our main market (USA, Australia, Canada and Europe)

What is the main difference between the Electric and Hydraulic construction models?
Electric models are powered by electric servos or motors and do not require hydraulic oil to operate. They are essentially mechanical models that are simpler in design and function primarily through electronic components.
On the other hand, hydraulic models operate using hydraulic oil, which is essential for their function. These models require a sufficient amount of hydraulic oil to operate effectively. Operationally, hydraulic models are better than electric ones. This strength is not just in terms of build quality but also in their operational capabilities, allowing them to scoop, move, and drive with greater force and efficiency.
What the difference between Huina and Double E models.
Huina is more of like a budget rc construction model brand, it offers range from the Huina 1535-1 to Huina 1599. The price of the models pretty much tell it all. If you are looking to dig and enjoy more you will have to look at models such as Huina 1593, Huina 1583, Huina 1594, Huina 1580 and Huina 1599. The Double E is also a budget or an affordable RC construction brand unlike the Huina brand they have fewer models but they all offer amazing experiences, they are a licensed Volvo RC construction manufacturer. Their Double E EC160e RC Excavator is one of customers favorite models.
Which is better Huina 1580 V4 RC Excavator or Double E Volvo EC160E RC Excavator?
Both models offer robust capabilities and functionality, ideal for those seeking a realistic digging experience. The Huina 1580 models the CAT 330DL excavator, while the Double E Volvo EC160E replicates the real-life Volvo EC160EL. One notable advantage of the Double E is its openable door feature, which the Huina 1580 lacks. In terms of power, the Double E EC160E is more powerful as it has performance levels similar to hydraulic models like the Kabolite 336GC/961 RC Excavator, making it exceptionally powerful among electric RC excavators. Its enhanced scooping strength and the prestige of being an officially licensed Volvo product also contribute to its popularity. However, the Huina 1580 remains a commendable option with its own set of admirers.

Proper maintenance is crucial for the longevity and performance of your RC construction model. Here are essential tips on how to handle and care for your model effectively:
-
Handling an Excavator: Avoid lifting an excavator by its boom. This can put undue stress on the servo mechanism, potentially leading to damage or failure.
-
Handling a Wheel Loader: Do not lift a wheel loader by its bucket. Similar to the excavator, this can damage the bucket's servo mechanism.

Operating Limits: Always respect the mechanical limits of your RC model. Forcing the machine beyond its capabilities can cause premature wear or irreversible damage.

Hydraulic Oil: Use only the recommended hydraulic oil for hydraulic RC models. This ensures smooth operation and protects the internal components.
