FAQ
I. Product-Related Questions
Q: Which brands/models of drones are your flight controllers and ESCs compatible with?
A: Our flight controllers and ESCs are compatible with mainstream FPV drone models (e.g., DJI FPV, BetaFPV). You can provide your specific drone model, and we will help confirm compatibility. The compatibility range is also marked on the detail pages of some products, which you can check first.
Q: How to choose the right motor parameters for myself?
A: The core factor is your usage scenario. For racing drones, high-speed motors are recommended (e.g., 2207 series with KV rating 2400+). For aerial photography/cross-country drones, medium-to-low KV motors with higher torque are better (e.g., 2306 series with KV rating 1700-2000). If you are unsure, contact customer service and provide your flight needs to get recommendations.
Q: What is the maximum transmission distance of your VTX (Video Transmitter)? How stable is the signal?
A: The transmission distance varies by VTX model (ranging from 1 to 5 kilometers; specific parameters are marked on the detail page). All VTXs use anti-interference chips, ensuring stable signals in unobstructed environments. We recommend using antennas of the same brand to further improve transmission performance.
Q: Do you provide technical parameter documents (e.g., wiring diagrams, firmware update packages) for the products?
A: All products come with supporting technical documents. After placing an order, you can obtain them in the "Order Center - Download Area" or contact customer service to receive them directly. Firmware update packages are updated regularly; you can follow the "Resource Center" section on the website.
II. Order & Payment Questions
Q: Can I modify the delivery address or product model after placing an order?
A: You can contact customer service to modify the address/model within 12 hours of placing the order (provided the order has not been shipped). For orders exceeding 12 hours or already shipped, the address/model cannot be modified, and you need to follow the after-sales process after receiving the goods.
Q: Which payment methods are supported? Is the payment secure?
A: We support mainstream payment methods such as PayPal, Visa. All payment processes are protected by SSL encryption, and we do not store your payment information, ensuring security.
Q: What should I do if the payment fails?
A: First, check your payment card balance, expiration date, or whether the "cross-border payment" function is enabled. If the problem persists, try a different payment method or contact the payment platform's customer service for troubleshooting. You can also take a screenshot of the failure page and contact us to help identify the issue.
Q: Can I request an invoice? What additional information is needed?
A: Electronic invoices (PDF format by default) are available. When placing an order, fill in the billing information such as company name and tax ID in the "Remarks" column. The invoice will be sent to your reserved email within 1-2 working days after the order is completed.
III. Logistics & Delivery Questions
Q: How long does it take to ship an order? How to track the logistics progress?
A: Orders will be shipped within 1-3 working days after successful payment (delays may occur during holidays). After shipment, an email with the tracking number will be sent. You can enter the tracking number in the website's "Order Center" or on the logistics official website (e.g., DHL, FedEx) to check the progress.
Q: How long does international logistics take? Who bears the customs duties?
A: Logistics time varies by destination: 5-10 working days for North America/Europe, 3-7 working days for Southeast Asia, and 7-15 working days for other regions. Customs duties are borne by the recipient (customs policies vary by country; we recommend checking the local duty standards in advance).
Q: What if the package is lost or damaged during logistics?
A: If the package is lost, we will assist in claiming compensation from the logistics company and arrange a re-shipment or refund for you. If the package is damaged, you need to provide "photos of the damage + photos of the shipping label" within 48 hours of delivery, and we will arrange a re-shipment or return/refund.
IV. After-Sales & Support Questions
Q: What is the warranty period of the products? What does the warranty cover?
A: All products come with a 6-month warranty (starting from the date of receipt). The warranty covers performance faults caused by non-human damage (e.g., unconnectable flight controllers, burned ESCs), but does not include damage from drops, water ingress, or modifications.
Q: What conditions must be met for returns or exchanges? What is the process?
A: Returns are not accepted for performance faults caused by non-human damage. For exchanges or replacements due to quality issues, we will cover the shipping costs. The process is as follows: Contact customer service to apply → Obtain the return address → Send back the product → Refund/resend after inspection.
