BlueCap Australia
A 25 kg fuel-powered UAV helicopter used as BlueCap's airborne magnetic, LiDAR and imaging platform.
Developed for demanding drone geophysical operations, BlueCapHeli® enables high-resolution data acquisition in mountainous, remote, and infrastructure-limited environments while significantly reducing operational complexity and survey costs compared to both conventional crewed helicopters and battery-powered electric drones.
The BlueCapHeli® UAV helicopter platform was designed & developed by our company in Australia between 2023 and 2026 and has been manufactured in-house in Perth, WA since 2025.
According to operational flight logs, the combined airborne flight time of the entire BlueCapHeli® fleet exceeded 400 hours as of mid-May 2026.
The 5 BlueCapHeli® helicopters currently in operation are registered with CASA for operation within the single-rotor liquid-fueled helicopter category up to 25 kg.
Single-rotor liquid-fueled helicopter category.
Swappable payloads: BlueCapBird® magnetometers, gamma spectrometers, and BlueCapLidar® systems.
8h or 3h endurance: two interchangeable 10L and 3.2L fuel tank configurations.
Redundant 7-link communications architecture comprising dual 4G LTE modems, Starlink Mini satellite connectivity, and four independent long-range RF links for C2, telemetry, and failsafe operation.
Motorized winch system for in-flight real-time control of suspended sensor altitude.
Motorized carburetor system automatically adjusts fuel mixture in real time to maintain optimal engine performance and stable operation across altitudes from 0 to 2,500 m.
9W aviation-grade high-intensity LED strobe beacon for enhanced airspace visibility and compliance with operational aviation safety requirements.
Continuous onboard battery charging without manual servicing: engine-driven generator with integrated smart Li-Ion battery.
Flight coverage: up to 800 line km per day per helicopter
Cruise survey speed with magnetometer or LiDAR payload: 100 km/h
Fuel consumption: 1.1 L/hour during flight operations
Rapid turnaround refueling: complete quick-swap fuel tank replacement instead of manual in-field refueling
Designed for mountainous & forested regions
Before every new survey campaign, each helicopter drone is fully disassembled, inspected, and rebuilt, with any components showing signs of wear or uncertainty proactively replaced prior to deployment.
Each helicopter is operated by three licensed BlueCap remote pilots to maintain continuous monitoring of flight systems, payloads, and onboard sensors.
Mandatory pre-survey autorotation testing through in-flight engine shutdown procedures.
Backup helicopter platforms are always deployed on mission to ensure uninterrupted operations and prevent delays in client data delivery
Secured multi-operator control modes: multiple drone pilots per helicopter or coordinated control of multiple helicopters by a single remote pilot.
The Bell 206 JetRanger has been the de facto industry standard for airborne geophysical surveys — especially magnetic surveys — for over 40 years.
We don't compare with Bell 206 because it's weak. We compare because it's the benchmark.
Comparison shows how much BlueCapHeli® reduces costs in familiar terms: Same average survey speeds, similar external sensor payloads (magnetometers, Lidars, gamma spectrometers).

BlueCapHeli® outperforms it in almost every metric — cost, safety, autonomy, altitude, fuel, crew — and that's exactly the story clients want to see.
Both Bell 206 and BlueCapHeli® can carry high-precision magnetometers (1–3 pT sensitivity).
But true data quality depends not just on the sensor — it depends on altitude stability and terrain tracking.
The closer and more consistently a sensor follows the terrain, the more accurate and interpretable the magnetic data becomes.
Explorers today put sustainability, HSE, and continuity first. That means minimizing incident likelihood, limiting environmental impact when incidents do happen, and keeping programs on schedule.
Shared history and data. We have operated electric multirotor fleets ourselves in the past — across long campaigns and harsh sites. From real operations, incidents occur on average about once every 7 flight days (unplanned landings, component failures, battery events, etc.). That frequency is manageable only if consequences are small and contained.
The aging multirotor reality. Many contractors — and previously we as well — use electric hexacopters such as the Skylle 1550 (MMC). New production of this model ended years ago; all surviving airframes in the market are aging. As components wear and spares become scarce, failure likelihood rises.
Failure mode over operating sites. With a deep loss of thrust, a multirotor descends ballistically (these units typically have no parachute). Most carry two Li-Po packs (~5 kg total); on impact or cell damage, thermal runaway can self-ignite and re-ignite. Standard CO₂/dry-powder extinguishers suppress flames but don’t stop runaway; effective response requires heavy water cooling and isolation. A crash from 40–60 m onto hard infrastructure or dry bush creates a high fire and loss risk, even when insured.
Controlled, non-ballistic landings. Helicopters have a physics advantage: if the engine or electronics fail, the aircraft enters autorotation. The airflow keeps the rotor spinning, brakes the descent, and enables a controlled, non-ballistic, soft touchdown in the nearest safe area. This localizes impact, reduces fire risk, and protects schedules — exactly what sustainability and HSE demand.
Fuel behaviour matters. Gasoline is flammable, but unlike Li-Po it does not run into self-sustaining thermal runaway when mechanically damaged. That difference is crucial for incident behaviour and suppression effort.
We design and build the helicopters ourselves. For each project we field newly built or freshly assembled and tested airframes — we don’t push “tired” machines into dusty, hot, or dry environments where hidden electronics faults are hard to detect.
We prove safety with deliberate fault-injection tests. Before missions, at safe altitude over a prepared zone, we intentionally trigger failures to validate that this airframe’s emergency modes work:
Only after these checks do we clear the aircraft for production sorties.
Allowing worn electric multirotors to fly over operating mines, dry bushland, and people carries unacceptably high consequence risk (uncontrolled descent and Li-Po fire). Bluecap helicopters deliver controlled failure outcomes (autorotation), lower fire risk, and program continuity — aligned with modern sustainability and HSE standards.
