The EFT K20 Agricultural Drone Frame is a new-generation professional agricultural UAV frame designed for crop spraying, fertilizer spreading, cleaning applications, delivery missions, and multi-purpose unmanned vehicle operations.
Developed as part of the EFT K20 / K30 new-gen frame platform, the K20 combines a compact foldable structure, modular three-part layout, strong truss frame, and versatile payload compatibility to provide a reliable base for professional drone builders, agricultural UAV manufacturers, and industrial operators.
20L Agricultural Spraying Platform
The EFT K20 is designed for 20L agricultural spraying applications, making it suitable for crop protection, plant protection, liquid fertilizer spraying, pesticide application, orchard treatment, and precision agriculture.
Its 20L water tank configuration provides a strong balance between payload capacity, flight efficiency, and field productivity, making the frame ideal for professional agricultural UAV builds.
Multi-Purpose Modular Design
The K20 Agricultural Drone Frame is designed as a versatile UAV platform that can support multiple payload types.
Depending on configuration, one body can be equipped with a 20L water tank or a 40L spreading tank, making it suitable for spraying, spreading, cleaning, delivery, and custom industrial applications.
This makes the EFT K20 more flexible than a standard agricultural spraying frame and suitable for users who need one frame for multiple professional missions.
New Three-Part Layout
The EFT K20 features a new three-part layout with front electronics, central battery placement, and rear payload installation.
This layout helps improve balance, simplify integration, and make the internal structure cleaner for professional UAV assembly.
By separating the flight control area, battery area, and payload area, the frame supports easier maintenance and a more organized installation.
Compact Foldable Structure
The EFT K20 Agricultural Drone Frame features a compact foldable design, making it easier to transport, store, and deploy in the field.
Its small folded size is designed for convenient single-person handling, helping agricultural operators move efficiently between different work sites.
This makes the K20 practical for mobile spraying teams, agricultural service providers, and professional UAV operators.
Strong Integrated Truss Frame
The EFT K20 uses an integrated truss frame structure designed for strength, stability, and impact resistance.
The frame combines a robust body structure with strong arm connectors, helping provide the rigidity needed for agricultural spraying, spreading, cleaning, and delivery missions.
This durable construction supports reliable operation in demanding field environments.
Adjustable Battery Bay
The K20 frame features an adjustable battery bay compatible with multiple battery sizes.
This gives UAV integrators more flexibility when selecting power systems and allows easier battery installation for different mission profiles.
The recommended battery configuration for the EFT K20 is 14S 20000mAh, depending on the final propulsion setup and payload configuration.
Multiple Arm Options
The EFT K20 Agricultural Drone Frame supports multiple arm configurations, including 40 mm tube, 45 mm tube, and 45 mm motor-base integrated arm options.
This allows the frame to be adapted to different propulsion setups and professional UAV build requirements.
The recommended motor for the K20 is 9620 80KV, depending on the selected arm and aircraft configuration.
Simplified Electrical Layout
The EFT K20 includes a new electrical layout designed to simplify wiring and improve system integration.
The centralized electronics area helps reduce cable clutter and makes the installation of flight controllers, power distribution boards, GNSS modules, payload systems, and spraying electronics more straightforward.
This makes the frame suitable for OEM drone projects, custom agricultural UAV builds, and professional integration workflows.
Professional Agricultural & Industrial Applications
The EFT K20 Agricultural Drone Frame is suitable for a wide range of professional applications, including crop spraying, fertilizer spreading, plant protection, high-altitude cleaning, payload delivery, field operations, and industrial UAV development.
Its modular design makes it a strong platform for users who need a compact, versatile, and reliable drone frame for multiple mission types.
