AT-ELF Portable Multi-rotor Drone
- Takeoff weight: 1.4 kg empty / 2.4 kg max
- Payload: rated 800 g, max 1,000 g
- Endurance: 34 min @ 1.4 kg / 15 min @ 2.4 kg
Product Overview
The AT-ELF Portable Multi-rotor Drone is part of the Multi-rotor UAVs range, typically used for Close-range structural inspection. Key specifications: Takeoff weight: 1.4 kg empty / 2.4 kg max; Payload: rated 800 g, max 1,000 g; Endurance: 34 min @ 1.4 kg / 15 min @ 2.4 kg. Aerosys Technology supplies it EXW from Hong Kong; MOQ 1 SET.
Cylindrical, direct-drive multi-rotor drone with a 1:1 payload ratio and very low acoustic signature — rotor speed is only 30-50% of comparable multirotors, so noise blends into the urban background beyond 30 m. The folded cylinder cuts stowage volume by over 50% and supports hand, catapult or vehicle launch.
Multi-rotor UAV platforms for close-range work — inspection hovering, aerial delivery and small-area mapping where a fixed wing is impractical.

Frequently Asked Questions
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 carries 800 g for 34 minutes.
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.
I am not sure which component fits my build — can you help me choose?
Yes. Tell us your platform, all-up weight, voltage, required control range and operating environment, and we will point you to suitable options. As a rule of thumb: size the propulsion and battery pack around the all-up weight and your thrust-to-weight target first, then match the flight controller and video link to the required range and payload, and choose the ground control station last. If two people need to work at once — for example a pilot and a camera operator — a dual operator system lets one fly the aircraft while the other controls the gimbal over a single link.
What does Aerosys Technology supply?
We are a manufacturer of unmanned aircraft, unmanned ground vehicles and the components that support them, and have been building and shipping them since 2018. Our catalogue covers 108 product models across 8 categories: Ground Control Stations, Video and Data Links, Gimbals and Cameras, VTOL Fixed-Wing UAVs, Multi-rotor UAVs, Unmanned Ground Vehicles, Mowers and Lawn Equipment, and Drone Detection and Tracking — serving commercial operators, system integrators and enterprises worldwide from our base in Hong Kong.
What is the minimum order quantity?
It depends on the product line. Complete platforms such as VTOL aircraft and unmanned ground vehicles are quoted per set. Ground control stations, gimbal systems and video link systems are quoted on a 5-unit basis. Individual components and mowers are available from a single piece. The MOQ for each item is listed on its product page.
How do I get a quotation, and how long is it valid?
Send us the model numbers and quantities you need — WhatsApp is the fastest route, and email works too. 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 a WhatsApp message alone is not an accepted order.
