BlueCap Australia
BlueCapHeli® — long-endurance petrol drone helicopter
BlueCapHeli® is a BlueCap-operated 25 kg long-endurance petrol UAV helicopter for magnetic, LiDAR and radiometric survey services, not equipment sales.
BlueCap-operated airborne carrier · designed in Australia
BlueCapHeli® carries magnetic, LiDAR, radiometric and imaging payloads over large, remote and rugged survey areas.
The aircraft, payload, remote pilots, field communications and processing workflow are delivered as one BlueCap survey service. BlueCapHeli® is not sold or leased as standalone equipment. In international specifications, the same fuel class may be described as a gasoline-powered or gas-powered drone helicopter; Australian copy uses petrol.
Two tanks. One survey aircraft. The mission selects the endurance.
The 3.2 L configuration supports compact survey cycles and quick field service. The 10 L configuration provides additional mission-design margin for remote polygons, long transit legs and extensive production lines. A larger tank is not automatically the better survey plan.
BlueCap-operated survey aircraftThe platform is integrated with the payload, flight crew and data workflow. It is not sold or leased as standalone equipment.
10 L configurationUp to 8 h
Long-endurance fuel cycle
Evaluated when distance to the survey block or long production lines would make frequent returns inefficient.
normal survey speed
Maximum cruise is 140 km/h. For radiometric acquisition BlueCap can hold a stable 20 km/h terrain-relative flight profile when required by the measurement plan.
registered category
CASA single-rotor liquid-fuelled helicopter category up to 25 kg; the approved mission configuration remains controlling.
dry mass
Aircraft mass before fuel, payload and other mission-specific equipment are added.
maximum static lift
The upward force measured while the helicopter is held in place. It shows lifting capability; approved take-off mass still sets the usable fuel and payload.
Petrol propulsionEngine-driven generatorSmart Li-ion flight power
A hybrid onboard power architecture keeps the aircraft battery charged in flight without implying electric rotor propulsion. The flight battery does not need to be removed or charged between fuelled missions.
Engineered as a connected survey carrier — not a bare airframe
BlueCap designed and developed the platform in Australia between 2023 and 2026 and has manufactured it in-house in Perth, WA since 2025. Each aircraft is configured around the payload, terrain, communications coverage and approved operating plan.

More people can supervise. More than one path can bring it home.
BlueCapHeli® keeps approved-route execution, independent oversight and the direct-radio contingency path distinct.
Approved-route lockNo arbitrary point-and-fly control
No user can steer or redirect the helicopter to an arbitrary location. It flies only the route agreed and approved before take-off; authorised intervention is limited to permitted safety actions such as Stop Mission and Return-to-Base.
Live, log and replay visibility
Authorised aviation regulators and airspace controllers can observe the aircraft in real time, inspect its flight logs and replay recorded missions. Where operational authority requires intervention, approved access can stop the survey mission and initiate Return-to-Base, but never redirect it to an arbitrary destination.
Encrypted internet control
BlueCapHeli® does not rely on a conventional handheld transmitter and does not accept point-and-fly steering. BlueCap pilots supervise the approved mission and issue only permissioned commands through redundant encrypted internet channels, with fingerprint confirmation for critical actions.
Direct RF Return-to-Base
A restricted direct-radio controller remains available over approximately 10–15 km line-of-sight. It is not a manual steering handset: in an unforeseen situation it can issue Return-to-Base directly, taking priority over the internet control path.
Adaptive engine management
Smart fuel–air control for real survey terrain
Survey terrain can change engine conditions by hundreds of metres inside one project. BlueCap built the control response for the climb, descent and changing air density that follow.
01 / 04
Interchangeable survey payloads
BlueCapBird® magnetometers, Medusa gamma spectrometers, BlueCapLidar® and imaging systems are integrated as project configurations.
Active payload altitude
BlueCapWinch® provides motorised real-time control of a suspended sensor independently of the carrier's immediate vertical motion.
Airspace visibility
A 9 W aviation-grade high-intensity LED strobe supports operational visibility and the applicable aviation-safety plan.
Low-noise petrol flight03
Petrol endurance. Electric-drone-like sound levels.
BlueCap developed an innovative exhaust silencer that substantially reduces the normal acoustic presence of a petrol engine. The result is a long-endurance survey helicopter that remains close to an electric heavy-lift drone in BlueCap's same-condition hover measurement.

A field photograph of the installed low-noise exhaust and silencer will replace this technical placeholder.
People nearby
The quieter exhaust is less intrusive around communities and work crews and avoids a persistent petrol-engine note becoming a nuisance during long survey programmes.
Animals and wildlife
Lower acoustic presence helps reduce avoidable startle and disturbance around livestock and wildlife while the project flight plan retains its site-specific controls.
Long field days
Lower noise exposure reduces fatigue for pilots, spotters and field personnel working near the operating base across repeated survey sorties.
Field productivity is a system outcome — not an endurance multiplication
Useful line-kilometres depend on survey geometry, turns, transit, terrain, exclusions, payload behaviour, weather, aviation approvals and field QC. BlueCap combines aircraft endurance with repeatable servicing, fleet redundancy and immediate acquisition review.

Campaign rebuild
Before a new survey campaign, each helicopter is disassembled, inspected and rebuilt; uncertain or worn components are replaced before deployment.
Backup aircraft
A backup helicopter is deployed on every mission to protect programme continuity and the client delivery schedule.
Continuous oversight
Remote pilots monitor aircraft systems, payload behaviour and onboard sensors rather than treating autonomy as unattended operation.
Scalable control
Secure pilot handover and multi-aircraft coordination are supported where staffing, permissions and the approved plan allow them.
Same survey. Fewer field days. Lower delivery cost.
This comparison is based on BlueCap's late-2025 field experiment with the same suspended BlueCapBird® magnetometer. Results from the DJI Matrice 600 and BlueCapHeli® are normalised to one identical 9 × 8 km client deliverable so field duration, aircraft programme time and direct team cost can be compared on the same survey basis.

The sensor and drape profile shape the recorded anomaly
Both aircraft can carry 1–3 pT-class magnetometers. Sensitivity alone does not control spatial resolution.
Safety planning starts with the consequence of failure
The question is not whether an aircraft can fail. It is how the particular airframe is maintained and tested, what recovery modes remain available, how energy-source hazards are controlled and how people, infrastructure and dry country are protected.
Autorotation changes the descent outcome
With rotor and flight-control authority available, airflow can keep the rotor turning and retain directional control toward a suitable touchdown area. It reduces descent severity; it does not guarantee an incident-free landing.
Petrol and Li-Po require different controls
Petroldoes not self-heat after impact; leaked fuel is contained and kept away from open flame and other ignition sources
Li-Poimpact damage can short cells and initiate self-sustaining thermal runaway
Across years of BlueCapHeli® operations, BlueCap has never recorded a helicopter fire. Remote pilots and spotters are trained for fuel and fire response, and spotters carry fire extinguishers in the field. Petrol and Li-Po still require different prevention, isolation and emergency procedures.
Emergency modes are tested before production sorties
Deliberate checks are performed at safe altitude over a prepared area. The aircraft proceeds only after the required modes are verified.
- 01Engine shutdown / partial power loss
- 02Datalink loss / loss-of-control scenarios
- 03Actuator and drive jamming simulations
Newly built or freshly assembled
Each project receives a newly built or freshly assembled and tested aircraft rather than an airframe with uncertain component condition.
Pre-survey autorotation test
A deliberate in-flight engine-shutdown procedure is completed before the aircraft is cleared for production work.
Defined stop criteria
Weather, communications, payload behaviour, reserve, landing options and exclusion zones remain explicit reasons to stop or alter a sortie.
Project-specific aviation case
The controls support the survey HSE plan; they do not replace CASA permissions, site controls or the risk assessment for the actual project.
