Shivnetra 18"

The Shivnetra 1.0 is an agile, field-proven aerial surveillance and multi-mission quadcopter platform built around an Ironman 650 full carbon fiber airframe. Engineered with Toray 3K matte twill carbon plates and 16 mm hollow pure carbon fiber arm tubes, this first-generation architecture combines an ultra-lightweight bare frame mass of just ~476 g with rigid structural damping. Built on a symmetric 650 mm diagonal wheelbase, the airframe is optimized to swing 12 to 15-inch carbon fiber propellers, providing an agile, highly serviceable platform that excels in aerial reconnaissance, basic orthophoto mapping, and perimeter patrol.

Its field-deployable footprint uses heavy-duty downward and inward folding arm clamps paired with high-clearance folding landing gear, collapsing flat in seconds for single-operator vehicle trunk or backpack transport. With an empty PNP system weight of approximately 1.8 to 2.2 kg and a Maximum Takeoff Weight (MTOW) of 4.0 to 4.5 kg, it provides a steady 800 g to 1.5 kg payload margin for electro-optical sensors, mapping cameras, and search telemetry.

The open central deck features a dual-tier carbon mounting sandwich that provides direct accessibility for open-source autopilots (such as Pixhawk 2.4.8, Pixhawk 4, or Cube Black running ArduPilot or PX4) with an elevated GPS mast to ensure compass isolation from high-current battery loops. Component ventilation is passive and open-air, with ESCs either tucked cleanly beneath the motor clamping mounts on the 16 mm tubes or secured within the central deck perimeter. For underslung payloads, the platform utilizes an integrated dual 10 mm carbon rail suspension system, featuring vibration-damping silicone isolators and adjustable forward-aft sliding brackets that allow operators to balance the system’s center of gravity (CG) when mounting 2-axis or 3-axis EO/IR zoom camera gimbals, compact photogrammetry sensors, or multispectral cameras.

The propulsion and power distribution setup is engineered around a reliable medium-voltage 4S (14.8 V) to 6S (22.2 V) LiPo architecture. The dual under-rail battery plate accommodates packs ranging from 5,200 mAh to 10,000 mAh (or high-density 6S Li-ion equivalents). When paired with matched brushless motors—such as 380–400 KV motors on 6S swinging 14–15" props or 600–700 KV motors on 4S swinging 12–13" props—the Shivnetra 1.0 delivers sustained mission endurances of 20 to 32+ minutes, depending on the payload configuration. Its low parts complexity, accessible spares, and reliable flight dynamics make the 1.0 an efficient tactical scouting and prototyping platform that directly paved the way for the enclosed, high-voltage 2.0 series.
