Deployments
Gandiva — Interceptor quadcopter · swarm-capable

Gandiva

Interceptor quadcopter · swarm-capable

Gandiva is a counter-drone system in two parts: a detection layer that uses multi-sensor fusion to spot and track a hostile UAV, and an interceptor layer that deploys drones to bring it down — the whole engagement run from a single Ground Control Unit. Each interceptor is a carbon-fibre 450-class quadcopter, stabilised by an ArduPilot autopilot and fitted with a kinetic tip. It dashes at 90–126 km/h, and 2–10+ can fly together for a layered, sensor-cued intercept.

Swarm — Autonomous master–slave swarm · distributed intelligence

Swarm

Autonomous master–slave swarm · distributed intelligence

Swarm is a coordinated team of drones: one 'master' leading any number of others, all built on the 5-inch Zeus quadcopter. They fly as a single formation, covering more ground than a lone UAV while the mission carries on even if a drone drops out. If the master is lost or neutralised, another drone automatically takes over the lead and the rest fall in behind it — so there's no single point of failure. The swarm's intelligence runs onboard each aircraft, coordinating the formation over a long-range radio link, with every drone on a proven ArduPilot autopilot for stable, GPS-guided flight. Automatic return-to-launch and auto-land failsafes bring the drones home safely, and the whole swarm is flown and monitored from a single ground station for tactical, surveillance and autonomy research.

Indrajit — Fibre-optic FPV · EW-resilient

Indrajit

Fibre-optic FPV · EW-resilient

10-inch FPV quadcopter with fibre-optic tether for electronic-warfare-resistant command and video. Four range configurations (2 / 5 / 10 / 20 km), 90–100 km/h cruise, analog or digital HD video options. The GCU converts digital signals to optical for jam-proof terminal control.

Nayanavat — Fuel-engine target drone · adversary-simulation trainer

Nayanavat

Fuel-engine target drone · adversary-simulation trainer

Two-stroke fuel-engine target drone on a balsa-and-plywood airframe, configurable with OS 0.46 / 0.56 or DA / DLE 35 engines. Built for air-defence unit training and gunnery practice. Simulates hostile-aircraft flight characteristics and radar signatures more safely and economically than manned targets.

Phoenix — Balsa fixed-wing FPV · low-cost, expendable

Phoenix

Balsa fixed-wing FPV · low-cost, expendable

A low-cost fixed-wing built from balsa and plywood and flown line-of-sight through FPV goggles. Battery-electric, shipped as an ARF kit, roughly 3 kg all-up with a 1 kg payload bay and 10–15 minutes on a charge out to 5–6 km. No autopilot suite: manual stabilisation and a clean video feed to the pilot. The wooden airframe keeps unit cost low enough to fly it as an entry-level trainer or treat it as expendable on short-range tactical tasks.

Eagle Eye — Mid-range fixed-wing · tactical recon

Eagle Eye

Mid-range fixed-wing · tactical recon

Lightweight mid-range fixed-wing UAV for tactical reconnaissance and survey missions. Composite or laser-cut balsa airframe, battery-electric propulsion, ArduPilot autopilot with Auto / Loiter / Stabilize / RTL flight modes. RF-primary comms with optional GPS telemetry.

Flight Time
Up to 40min
Range
30–50km

Icarus II — Production-tuned VTOL · long-range ISR

Icarus II

Production-tuned VTOL · long-range ISR

Production-tuned variant of the Icarus composite VTOL, sharing its CF/FG airframe and ArduPilot autopilot. Configurable electric or IC-engine propulsion, ARF kit assembly. 50–60 min endurance, 60–80 km operational range on a single charge, GPS-primary comms with RF backup.

Zeus — Hybrid-frame FPV trainer · ArduPilot safety net

Zeus

Hybrid-frame FPV trainer · ArduPilot safety net

Hybrid carbon-fibre and fibreglass FPV platform that bridges high-speed racing and stabilised camera drones. The rigid CF core keeps manoeuvres precise while impact-resistant fibreglass arms and reinforced motor mounts absorb the hard landings of the training phase. An ArduPilot flight controller gives new pilots a safety net: auto-level Stabilize, GPS Loiter, and one-switch Return-to-Launch with signal-loss and low-battery failsafe. Live telemetry (voltage, GPS, altitude, speed) streams straight into the pilot's goggles.
