EFT E420P
Agriculture
Drone Frame
The E Series Quadcopter delivers 20 kg payload capacity in a one-piece molded, fully waterproof airframe built for real-world field operations.
Built for the Field.
Designed to Last.
Every detail of the E Series is engineered for professional agricultural operations — from airframe to power system.
Cross-Fold Structure
Staggered dual-arm folding compresses the footprint by over 60%. Field-ready in under 60 seconds — single operator transport.
One-Piece Molded Body
Injection-molded high-strength polymer composite — no assembly joints. Vibration-tested and fall-certified for professional field use.
Fully Waterproof Body
UV-treated bright red coating. Scratch and corrosion resistant. Tolerates direct water wash after every mission — pesticide-safe.
Integrated Power Routing
Separate moulded channels for signal and power. Centralized distribution reduces EMI, improving flight controller and GPS stability.
Enlarged Tank Inlet
Wider fill port reduces refuelling time. Anti-spill geometry performs on sloped terrain — essential for hillside orchards.
Reinforced Power Plug
Side-routed battery interface with optional AS150/AS150U connectors. Safer hot-swap ergonomics rated for 10,000+ cycles.
Every Angle.
Every Detail.
Three Models.
One Platform.
Choose the right capacity for your operation — the E410P, E416P, and E420P share the same premium airframe architecture.
Engineering Advantages
Cross-Fold Arms
for Easy Transport
The E Series' signature cross-folding arm mechanism reduces the drone's footprint by over 60% when packed. Staggered fold angles prevent arm collision and enable one-handed deployment in under 60 seconds — critical for remote field operations.
One-Piece Body
Zero Weak Points
Traditional drone frames assemble dozens of separate parts — each joint a potential failure point. The E Series uses a single injection-molded polymer composite body that eliminates all joints. The result: a frame that withstands hard landings, vibration, and field abuse without degradation.
IP67 Waterproof
Wash It Down Daily
Agricultural drones operate in chemically aggressive environments. The E Series' UV-treated coating resists pesticides, fertilisers, and corrosive agents. After every mission, simply wash the entire drone with water — no teardown required.
Where the E4 Performs.
From precision crop spraying to industrial inspection — the E Series is the operator's first choice across demanding environments worldwide.
Crop Spraying
Uniform liquid distribution — rice, wheat, orchards, tea.
Fertilisation
GPS-guided spreading of granules, seed, soil amendments.
Survey & Mapping
Terrain mapping with multispectral or LiDAR payloads.
Precision Farming
Variable-rate application with GPS waypoint automation.
The Professional's Choice.
Factory-Direct Pricing
Eliminate distributor margins. EFT sells direct to operators and integrators worldwide.
Modular Ecosystem
Compatible with EFT payloads, DJI Agras, XAG, and Ardupilot flight controllers.
Globally Proven
Deployed across 40+ countries — Asia, Africa, Latin America, Europe. Every climate tested.
Easy Maintenance
Distributed electronics and snap-fit arms allow motor/ESC replacement in minutes in the field.
Private Label / OEM
Brand the E Series under your own label — custom colours, decals, full documentation packages.

EFT E420P 20L 4 Axis Agricultural Drone Frame – Heavy Payload UAV for Precision Farming in India
Introduction
The EFT E420P 20L Agricultural Drone Frame is powering the next generation of smart farming in India. As agriculture rapidly moves toward automation, farmers and agri-businesses are facing increasing labour shortages, rising input costs, unpredictable weather patterns, and the need for faster, safer pesticide spraying across large land areas. Traditional manual spraying methods not only waste water and chemicals but also expose workers to harmful toxins and fail to meet time-sensitive spraying demands.
Agricultural spray drones are the smart solution — and at the core of every high-performance drone lies a strong, precision-engineered frame.
The EFT E420P 20L Agricultural Drone Frame is a heavy-duty, 4-axis quadcopter platform specifically designed for large-scale pesticide spraying, fertiliser application, and modern UAV-based farming operations. Equipped with a 20-litre tank, a durable carbon-fibre and aluminium structure, and an approximate payload capacity of 22 kg, it is an ideal choice for drone service providers, agri-tech startups, and progressive farmers looking to build a professional-grade spraying drone in India without paying premium brand prices.
If you are looking for a reliable, high-payload 20L agricultural drone frame built for Indian field conditions, the EFT E420P delivers unmatched performance, durability, and value.
