Core Capabilities

Intelligent Flight Features

Engineered for real-world agriculture — precise obstacle avoidance, reliable night operations and clear visual feedback so every spraying mission is safer and more productive.

4D Precision Radar

Detects and navigates around trees, poles, power lines and uneven terrain in all directions — critical for slopes and inter-row spraying.

80W Bright Headlight

High-brightness headlight enables safe early-morning and night spraying, extending productive hours beyond daylight.

1080P HD Gimbal Camera

Stabilised live view on the controller gives the operator full situational awareness during every mission.

Built For Demanding Fields

Terrain-Aware, Payload-Ready

Terrain-aware flight, strong motors for the full 20 L payload, and modular design that keeps downtime low — built for varied terrain and climate.

25,000 mAh Battery

Engineering Architecture

Modular Design Excellence

Separated modules, independent data paths and service-friendly construction keep the aircraft stable in the air and easy to maintain on the ground.

Reliability

Separated CAN Design

PMU, FMU and RTK modules are separately plugged with independent protection — enhancing system stability under demanding field conditions.

Communication

Independent Avionics Module

Multi-channel CAN bus architecture ensures stable, reliable data transmission between all critical flight systems.

Installation

Injection-Molded Motor Base

Easy installation with no calibration required. Secure mounting that survives repeated transport and rough field handling.

Serviceability

Separated ESC & Motor

Replace only what fails instead of entire power assemblies — ideal for continuous commercial spraying seasons.

Field-Ready Construction

Built for Long Hours

High-current power distribution, advanced cooling, die-forged structure and multiple mechanical safety locks keep the aircraft flying day after day.

High-Efficiency Cooling Fan

Reduces motor temperature for stable long-duration spraying under heat.

High-safety dustproof and waterproof connector

High-Safety Connector

Dustproof and waterproof injection-molded plugs — reliable in dusty fields and monsoon conditions.

Die-Forged Structure

High-density aluminium alloy — compact, solid and ready for repeated transport and hard landings.

Anti-Off Arm Buckle

Dual-lock and shock-resistant buckles keep arms secure during aggressive manoeuvres.

High-current copper busbar power distribution board

High-Current PDB

Copper busbar with higher overcurrent capacity and lower temperature rise under full payload.

Injection-Molded Plugs

Waterproof, dustproof and wear-resistant for frequent battery and payload changes.

Local Application

Built for Diverse Agricultural Terrain

From lowland paddy to hill-country plantations — the 20 L platform is built for the crops and terrain that matter most.

🌾

Paddy Fields

Uniform pesticide, herbicide and nutrient application across large contiguous plots, reducing labour peaks during critical windows.

⛰️

Tea & Hill Estates

Terrain-following capability and obstacle radar make slope spraying safer and more precise, with lower chemical waste on contours.

🌴

Coconut & Plantation Crops

Inter-row and canopy-edge spraying where ground equipment struggles — ideal for fragmented plantation layouts.

🥬

Vegetables & High-Value Crops

Targeted low-volume application. Night and early-morning operation helps avoid heat stress on sensitive crops.

🚁

Service Providers & Fleets

High daily throughput with multiple battery cycles. Modular design keeps maintenance predictable for commercial fleets.

💧

Wet / Soft Fields

Minimal soil compaction compared with tractors, with the ability to operate when ground is too soft for conventional equipment.

Typical Productivity

Depending on application rate and spray width, operators commonly achieve 5–10 acres per hour. Multiple battery sets allow a full day of productive work with proper logistics.

Practical Answers

Frequently Asked Questions

How much area can one full tank cover?

At typical agricultural rates (15–20 L/ha for many products), a 20 L tank covers roughly 1–1.3 hectares per fill. Actual coverage depends on the specific product rate and spray width selected.

What is real-world flight time with a full 20 L load?

Approximately 10 minutes under normal conditions. Empty endurance is around 17 minutes. Multiple batteries are recommended for continuous daily operations.

Is it suitable for hilly and plantation terrain?

Yes. The 4D radar and optional terrain-follow package help maintain consistent height and avoid obstacles on slopes and among trees.

Can the same drone do both spraying and granular spreading?

Yes. An optional 18 kg spreading system can be fitted for fertiliser or seed broadcasting, with quick changeover possible thanks to the modular design.

What about local regulations?

Commercial drone spraying typically requires civil aviation registration and operating approvals, which vary by country and region. Saivalabs can guide partners through the applicable process.

What support and training is available?

We provide operator training, maintenance guidance and ongoing technical support, with local partnership models available for fleets and service providers.
