Frequently Asked Questions

What does Aerosys Technology supply?

Our catalogue covers 272 product models across 13 categories. Behind that catalogue sits production in the Pearl River Delta and a commercial centre in Hong Kong that handles the contracting, freight, banking and export documentation cross-border trade depends on.

Orders, warranty, returns and OEM configuration

Do you ship internationally, and who handles customs?

Yes, we ship worldwide. Unless the order confirmation states otherwise, the buyer is the importer of record and is responsible for import licences, permits, product registrations, customs declarations, duty, VAT and any destination charges. We will not declare a false value, description or origin, and we supply the commercial invoice and documentation needed for clearance.

What does the warranty cover?

The warranty covers manufacturing defects arising under normal use and correct installation, for the product-specific period stated on the product page or order confirmation. It does not cover normal wear and tear, battery capacity degradation, crash or impact damage, water or moisture damage, incorrect voltage or incompatible equipment, unauthorised modification or repair, or operation outside published specifications. To claim, send the order number, model and serial number, a description of the fault, and photographs, video or logs as requested.

Can I return a product?

Eligible unused stock items may be returned within 30 days of delivery, subject to inspection and approval, and returns require prior written authorisation — contact us for an RMA number before shipping anything back. The item must be unused, uninstalled, unflown and unactivated, complete and undamaged, in its original packaging with labels, accessories and serial numbers intact. Customised or made-to-order items, anything installed or flown, and batteries or consumables that have been used or charged are not returnable unless confirmed defective or incorrectly supplied.

Do you offer OEM, custom configurations or custom bundles?

Yes. We support OEM configurations and custom bundles built around specific operational requirements, including motor, ESC and propeller combinations matched to a platform's thrust and voltage needs. Configured and made-to-order items follow the lead time stated on the order confirmation. Customised, configured or branded items are not returnable unless confirmed defective or incorrectly supplied.

What is the minimum order quantity?

It depends on the product line. Ground control stations are quoted on a 5-unit basis, while video and data links and camera payloads are quoted from a single unit. Complete platforms such as VTOL aircraft, multi-rotors and unmanned ground vehicles are quoted per set. Where a product page states a different MOQ, that page governs.

Are your prices EXW or delivered?

Published prices are in USD on an EXW basis unless the quotation says otherwise. EXW means the price covers the goods at our premises; international freight, insurance, import duty, VAT and destination charges are additional and are the buyer's responsibility. Send us your destination country and postcode and we will give you a delivered estimate.

How long does shipping take?

In-stock components are generally prepared within 1 to 3 business days after payment clears. Typical transit time is roughly 3 to 7 business days by international express (DHL, UPS or FedEx) and 7 to 21 business days by standard parcel service, with air or sea freight arranged for larger and heavier items. These are estimates rather than guarantees, because customs processing is outside our control.

Which payment methods do you accept?

Accepted methods are stated on the order confirmation and are typically bank transfer. Payment must be received in full before dispatch unless credit terms have been agreed in writing. Bank charges, currency conversion and intermediary fees are the buyer's responsibility.

How do I get a quotation, and how long is it valid?

Send us the model numbers and quantities you need by email. Quotations are issued in USD and are valid for 14 days from the date of issue unless a different period is stated. An order is confirmed only when we issue a written order confirmation and receive the agreed payment; a quotation or an email alone is not an accepted order.

Are the products genuine original-manufacturer products?

Yes. Every unit is sourced through verified supply channels with traceability back to the original manufacturer, and orders are inspected before dispatch. Products are supplied as OEM items, the manufacturers' standard warranties apply, and warranty periods are stated on the product page or on the order confirmation.

What if my order arrives damaged or incorrect?

Inspect the goods promptly and keep all packaging. Report shortages, wrong items or transit damage within 7 days of delivery, quoting your order number and providing photographs or video. Do not install, power on, fly or modify a product that may have been damaged in transit until we have given you instructions. Approved refunds are normally initiated within 5 business days after the returned goods have been received and inspected.

Can you ship batteries?

Yes, but batteries and other dangerous goods need special packaging, documentation and handling, and may ship separately from other items on the same order. This can affect the delivery schedule, so we confirm the arrangement when the order is placed. Batteries and consumables that have been used or charged are not returnable unless confirmed defective.

How do I choose between a multi-rotor and a VTOL fixed-wing UAV?

Match the platform to endurance and area first, payload second. VTOL fixed-wing suits missions beyond roughly 60 minutes or 10 km²: the AT-G10 flies 4 hours at 4 kg payload. Multi-rotors win for hovering, precision work and short heavy lifts — the AT-ELF is rated to 800 g of payload and flies 34 minutes at its 1.4 kg empty weight.

Which VTOL fixed-wing should I choose for a 30 kg payload?

Neither G-series model is a natural fit at 30 kg: the AT-G10 is rated to 10 kg payload and the AT-G190 is a 190 kg-class machine, so 30 kg sits far below its design point. Either fly the AT-G190 well below its rating or split the load across two AT-G10s. Send us the mission profile and we will size it.

What payload can the AT-G190 heavy-lift VTOL carry, and how long can it stay up?

The AT-G190 lifts 190 kg at a 470 kg maximum take-off weight, flying 5 hours at the full 190 kg or 27 hours at 60 kg, at a 200 km/h cruise. Two belly-mounted payload stations support mixed payload configurations in a single sortie.

What is the difference between the AT-T, AT-M and AT-S link series?

All three run on 1.4 GHz with real-time spectrum sensing and frequency hopping. The T series is anti-interference point-to-point, up to 300 km at 20 Mbps. The M series adds MESH networking to 128 nodes at 40 Mbps. The S series trades bandwidth for reach: 5 Mbps up to 500 km.

Which gimbal gives the longest detection range?

The AT-135D has the longest detection range in our gimbal line: person 11.1 km / vehicle 20 km. It pairs a 40x optical zoom with a 640×512 LWIR imager on a three-axis stabilised head. Next best is the AT-115S at person 11 km / vehicle 20 km.

Which ground control station has the longest control range?

The H30 has the longest control range in our ground station line, at up to 50 km of combined control and video. The UniRC 10 Pro follows at 45 km with a 1080P screen, adjustable 10/20 MHz bandwidth and hot-swappable endurance packs, and the UniRC 7 and UniRC 7 Pro run to 40 km. Range depends on the air unit and the link mode, so tell us the aircraft and we confirm the figure.

How many nodes can an AEROLINK MESH network support?

Up to 128 nodes in a network configuration across the M, S, D and X series; the point-to-point T series supports 3-node networking. One fabric carries control, telemetry, HD video and multi-sensor data across UAV, USV, UGV, robot-dog, maritime and mountain-relay nodes.

Do your EO/IR gimbals support 360-degree continuous rotation?

Yes. The AT-100T, AT-115T, AT-125T and AT-135T all provide N x 360 degree continuous azimuth with -120 to +40 degree elevation, and the ZT30 has a 360 degree continuous yaw axis. Continuous rotation lets you orbit a target without a cable wrap or a blind sector.

What video latency does your HD transmission system have?

The HM30 delivers 1080P over 20 km at roughly 150 ms latency, with remote control, telemetry and video combined on one link. Latency matters most for manual flight and live gimbal tracking; for mapping and survey work, link stability and range matter more than the last 50 ms.

What is the operating frequency band of the AEROLINK links?

All AEROLINK series operate on 1.4 GHz and support custom frequency bands. Transmit power ranges from 0-27 dBm on the compact AT-T27 up to 0-46 dBm (dual 40 W) on the AT-T46, AT-M46 and AT-S46, which dissipate 172 W at full output.

Do your gimbals work with ArduPilot and PX4?

The ZT30 accepts S.Bus, Ethernet, UDP/TCP and UART and is compatible with ArduPilot and PX4. AEROLINK links expose network, RS232, TTL and SBUS ports that connect to the flight controller over a serial link. Tell us your autopilot and we confirm the wiring before dispatch.

Are your products export-controlled, and what documentation do you provide?

Export licensing is the buyer's responsibility: the purchaser obtains export qualifications, licences and end-user documentation and complies with the import, export, sanctions and radio rules of China, the destination country and any transit country. We supply commercial invoices and standard shipping documents, and we do not support resale to sanctioned entities or conflict zones.

Do your radio links meet local frequency regulations?

The AEROLINK links run on 1.4 GHz and support custom bands, but the operating frequency, bandwidth and transmit power must comply with local radio regulations and the necessary licences must be obtained by the operator. Licensing, frequency configuration and regional suitability remain subject to contract and technical confirmation.

Are your products CE or FCC certified?

Certification is product-specific and stated on the product page or order confirmation where it applies; the certification field is empty for models supplied without a certificate. Because radio approval is country-specific, confirm the target market before ordering and we will tell you exactly what documentation ships with the unit.

Do you sell military or weapon-capable equipment?

Yes, in defined categories and through qualified channels. The catalogue includes loitering and strike UAVs, target drones and counter-UAV equipment. Strike-related products — loitering and strike systems, target drones and other defence-related equipment — are supplied only through Chinese enterprises holding valid military trade qualifications, and only for procurement conducted lawfully under the laws and regulations of the People's Republic of China. We screen end use and end user, and do not supply parties subject to sanctions or export controls; where an export licence is required, we will say so before we ship.

How are your prices set, and why are some products priced on request?

Published prices are USD on an EXW basis. A model marked Price on Request is quoted individually because configuration, quantity and destination determine the price. Its product page shows the applicable basis. Send the model, quantity and destination for a quote within one business day.

Do you offer volume pricing?

Yes. Ground control stations are quoted on a 5-unit basis, while video and data links and camera payloads are quoted from a single unit; VTOL aircraft, multi-rotors and unmanned ground vehicles are quoted per set. Larger volumes are quoted individually. Tell us the target quantity and we will return the applicable tier.

Why do some product pages not show a price?

A model appears without a price when its quote depends on configuration, quantity or destination. Its product page indicates the applicable basis, and the inquiry button opens our online form with the model already included. Add the quantity and destination; no email app is required.

Can your equipment be used for powerline inspection?

Yes. A typical fit is an AT-G10 VTOL for 2-hour line patrols or a multi-rotor for close tower work, carrying the AT-135T 40x zoom and 640x512 thermal gimbal, linked over the HM30 or an AEROLINK T-series link. Thermal and zoom channels together identify hot joints and damaged fittings.

Can the heavy-lift multi-rotors be used for aerial delivery?

Yes. The MT100 lifts 100 kg at a 200 kg maximum take-off weight with a 10 km control range and a 1500 m service ceiling; the M50 lifts 50 kg at 100 kg maximum take-off weight. Both ship with flight controller, power system, remote controller, camera and RTK.

Can your datalink equipment be used for maritime or mountain relay?

Yes. The AEROLINK architecture is built for UAV, USV, UGV, robot-dog, maritime and mountain-relay nodes, using point-to-point, point-to-multipoint, MESH and relay topologies. The S series reaches 500 km ground-to-air, and the AT-GE tracking gimbal with built-in RTK keeps the beam on moving targets.
