EFT E420P 20L 4 Axis Agricultural Drone Frame

EFT E420P 20L Agricultural Drone Frame

The EFT E420P is a professional 20L agricultural drone frame designed for crop spraying, precision agriculture, and commercial UAV applications. Built on a 4-axis quadcopter platform, the frame combines a durable carbon fiber and aluminum alloy structure with a large-capacity spray tank to support efficient agricultural operations.

Designed for compatibility with 14S LiPo battery systems, large agricultural motors, and professional spraying equipment, the E420P provides a reliable foundation for building custom agricultural drones. Its foldable design, modular construction, and high payload capability make it suitable for agricultural drone manufacturers, UAV integrators, drone service providers, research institutions, and precision farming projects.

Key Features

20-Liter Chemical Tank

The integrated 20L spray tank allows longer spraying operations with fewer refill interruptions, making the frame suitable for medium- and large-scale agricultural applications.

4-Axis Quadcopter Platform

The E420P features a 4-axis quadcopter layout, providing a stable platform for agricultural spraying while maintaining a relatively simple mechanical structure for assembly and maintenance.

Carbon Fiber and Aluminum Alloy Construction

The frame is manufactured using carbon fiber and aluminum alloy, providing a lightweight yet rigid structure capable of supporting agricultural payloads while resisting corrosion and vibration during field operations.

Foldable Arm Design

Foldable arms reduce the transport size of the aircraft, allowing easier storage and transportation between operating locations.

High Payload Capability

The frame is designed to support a complete agricultural payload, including the spray tank, battery, propulsion system, pump, and spraying accessories within the recommended operating configuration.

Modular Equipment Installation

Dedicated mounting locations simplify the installation of compatible flight controllers, propulsion systems, spraying equipment, GPS modules, and other agricultural UAV accessories.

Spray System Compatibility

The frame supports integration with diaphragm pumps, centrifugal pumps, and multiple nozzle configurations depending on the spraying system selected.

Stable Landing Gear

The reinforced landing gear provides adequate ground clearance and stable takeoff and landing on uneven agricultural terrain.
