EFT E416P 16L 4-Axis Agricultural Drone Frame

The EFT E416P is a 4-axis agricultural drone frame engineered for 16-litre payload spraying operations. Designed for crop protection and heavy-lift agricultural builds, this quadcopter frame provides a stable platform for custom integration. It utilises a standard folding arm mechanism to drastically reduce its footprint during transport while maintaining high structural rigidity in flight.

Key features

• 16-litre quick-release liquid tank system for rapid refilling cycles between flights.

• Folding 35mm carbon fibre arm tubes secured with aviation-grade aluminium joints.

• Enclosed central canopy seals the flight controller, power distribution and electronics against liquid and dust ingress.

• Integrated mounting points for standard agricultural spray pumps, flow meters and terrain radar modules.

• Wide stance and low centre of gravity prevent tipping on uneven agricultural terrain.

Specifications

• Structure: 4-Axis (Quadcopter)

This frame requires a dedicated heavy-lift flight controller such as the JIYI K++ or an ArduPilot-compatible system, paired with a 12S to 14S high-voltage power setup. The E416P serves as a barebones foundation for builders constructing professional crop-dusting and liquid-spraying multirotors.
