Warranty and the RMA process
Every unit carries a 12-month warranty against manufacturing defect. It does not cover crash damage, reverse polarity, water ingress on non-waterproof parts, or firmware you flashed yourself.
To raise an RMA, email the trade desk with the order number, the SKU, a photo or short video of the fault, and how many units are affected. We will confirm within one working day. Do not ship anything back before you have an RMA number — unannounced returns cannot be processed through customs.
Customs, duty and documentation
We ship with a commercial invoice and packing list as standard. CE / FCC / RoHS documentation is available for most SKUs on request, and we can supply a certificate of origin and MSDS for lithium batteries.
Duty and import VAT are set by your own customs authority, not by us. If you would rather not manage that, ask for DDP terms and we will quote a landed price that includes clearance.
Reaching the trade desk
The fastest channel is WhatsApp — the floating button on every page. Email works too and is better for anything with attachments or a parts list.
Hours are Monday to Saturday, 09:00–19:00 China Standard Time (UTC+8). Enquiries that arrive overnight are answered the next working morning.
Questions buyers ask
How long does a quote take?
Within six working hours for catalogue items. Non-catalogue sourcing requests can take up to 24 hours because we check the local supply chain first.
Can you ship to my forwarder in Shenzhen?
Yes, and it is often the cheapest option if you already consolidate. Give us the forwarder's address and your reference number.
What is the warranty period?
12 months against manufacturing defect, from the date of dispatch. Consumables such as propellers and batteries are covered for dead-on-arrival only.
Do you accept returns?
Yes, with an RMA number. Faulty goods are replaced or credited. Change-of-mind returns are accepted on unopened stock within 14 days, minus freight.
Can you pre-flash firmware before shipping?
Yes. Tell us the firmware version and the locked settings and we will apply them, for a small per-unit charge on runs above 50 pieces.
