04RC Helicopters

Batteries ship separatelyLithium batteries are always shipped in a separate parcel with their own tracking number, from both our China / HK and US warehouses. Batteries from China / HK travel through a dedicated battery shipping line, so they may arrive a few days after your helicopter.

05After You Order
Processing & Tracking
Applies to: all orders, including RC helicopters
How soon will my order ship?
- China / HK warehouse: in-stock orders placed before 5:00 PM (GMT+8), Monday to Saturday, are usually dispatched the same day. That's early morning in the US and mid-morning in Europe. Orders placed after the cut-off ship the next working day.
- US and EU warehouses: orders usually ship within 1 business day.
Pre-order items ship according to the production schedule, and you can check the latest status on our Production Updates page.
How do I track my order?
Once your order ships, we'll email you a tracking number. You can track your parcel on our Track Your Order page.
Please note that it can take a few business days after shipping for the first tracking update to appear. This is normal.
Why did my order arrive in more than one parcel?
If your order includes items from different warehouses, or both in-stock and pre-order items, we ship them separately so you get your in-stock items sooner. Each parcel has its own tracking number.
Prefer to receive everything together? Just leave a note at checkout or email us, and we'll do our best to ship your order in one parcel.
Do you ship fuel with engines?
No. For safety reasons, fuel such as nitro fuel, gasoline and alcohol can't be shipped by air. All our engines are shipped with empty tanks and no fuel, so you'll need to buy fuel locally before your first run.
Not sure which fuel your engine needs? Check the User Guide for your model, or email us and we'll be happy to help.
Do you ship to my country?
Yes, we ship to most countries worldwide, including the US, Canada, the UK, all of Europe, Australia and most of Asia.
Enter your address at checkout to see the shipping options for your location. If standard shipping shows $0, it's free.
Which carrier will deliver my order?
We choose the most reliable carrier for your destination. Standard shipping is mainly handled by YunExpress or UBI, and handed to a local carrier in your country for final delivery. Express shipping is mainly handled by DHL or UPS. US and EU warehouse orders are delivered by local carriers.
Can I send my order as a gift?
Of course. Our products have no price tags, and we never include priced documents in the package. You can leave a gift message in the order notes at checkout, and we'll include it in the package.
I need to change my shipping address.
Please email us as soon as possible with your order number and new address. We can update it as long as your order hasn't shipped yet. Once a parcel has shipped, we can no longer change the address. Depending on the carrier, you may be able to arrange a delivery change directly with them.
06Our Delivery Promise
If Something Goes Wrong
Applies to: all orders, including RC helicopters
Every product is quality-checked before it ships. If there's ever a problem with your delivery, here's how we'll help.
Missing partsWe recommend filming a short video while unboxing, as it helps us sort things out quickly. If anything is missing, just contact us within 7 days of delivery and we'll send the missing parts free of charge.
Damaged in transitSorry about that! Contact our support team within 7 days of delivery with a few photos or a short video of the packaging and the damaged part, and we'll send you a free replacement part for any damage that happened in transit.
No tracking updateIf your tracking hasn't updated for more than 10 days, email us your order number. We'll check with the carrier and keep you updated.
Please keep the original packaging until your issue is resolved, as the carrier may need it for an inspection. Every engine and kit also comes with a 1-year warranty against manufacturing defects.
My parcel seems lost, or says delivered but I don't have it.
Tracking hasn't updated for a while? Email us your order number and we'll check with the carrier. If the carrier confirms your parcel is lost, we'll resend your order or give you a full refund.
Marked as delivered but you can't find it? Please check with neighbours, building reception and your mailbox, and allow 2 business days, as parcels are sometimes scanned before they arrive. Still missing? Email us and we'll help you file a claim with the carrier, who is responsible for parcels marked as delivered.
If you added Shipping Protection at checkout, we'll resend your order or refund you directly.
What is Shipping Protection? Is it worth it?
Shipping Protection is an optional add-on at checkout that covers your parcel from our warehouse to your door.
With Shipping Protection:
- Lost parcel: we resend your order or give you a full refund, with no waiting for a carrier investigation.
- Stolen, or marked "delivered" but not received: we resend your order or give you a full refund.
- Priority handling: your replacement ships within 2 business days when in stock, and within 1 week otherwise.
Without it: we resend lost parcels once the carrier confirms the loss. Parcels marked as delivered are the carrier's responsibility, but we'll help you file a claim.
Either way: parts damaged in transit are replaced free, and every engine comes with our free 1-year warranty. Shipping Protection is not a warranty.
Claims for parcels marked as delivered must be made between 48 hours and 14 days after delivery. We may ask for a carrier investigation number or a police report, and we'll usually resend your order rather than refund it. Shipping Protection covers the address entered at checkout and allows one delivered-but-not-received claim per customer every 12 months.
07Order Cancellation
Need to Cancel Your Order?
Applies to: all orders, including RC helicopters
Plans change, we understand. Here's how cancellation works.
Before it shipsEmail us your order number and we'll cancel it free of charge. A full refund goes back to your original payment method, usually within 2 business days.
Please act fastIn-stock items often ship within 2–24 hours, so please contact us as soon as possible. If your order has already left our warehouse, we can no longer cancel it.
Already shippedOnce an order has shipped, we're unable to cancel it. You're welcome to accept the delivery and return it through our Refund & Return process. In this case, return shipping and any duties are at your own cost.
Exceptions and weekend requests
- Custom orders: once production has started, we're unable to cancel them, so we recommend checking your order details carefully before purchasing.
- Final Sale items: these orders are final and can't be canceled.
- Weekend requests: our support team works Monday to Friday, while our warehouse also ships on Saturdays. Cancellation requests sent over the weekend are handled the following Monday. If your order ships before we process your request, please accept the delivery and follow our return process.
If a parcel is refused on delivery, it is returned to us at extra cost, so we may not be able to offer a refund in that case. If you have any concerns about your order, please talk to us first and we'll do our best to help.
