17 years RC aircraft design & operations
UAV fabrication — Betaflight, ArduPilot, PX4
Commercial UAV operations — SE Queensland & a decade in the UAE

The Jäger's flight-control approach draws on seventeen years of RC aircraft design and hands-on UAV fabrication, across Betaflight, ArduPilot, and PX4, backed by commercial UAV operations experience in South-East Queensland and a decade in the UAE. Steven holds a CASA RePL with sub-25kg endorsement.

That background sits behind a simple observation: Australia talks about sovereign defence capability more often than it builds it. Volaris exists to close that gap, not wait for it to close itself.

The ULM-45 Jäger began as a question rather than a product brief — what would a man-portable loitering system look like if it were designed from first principles, for the way small units actually operate in the field, instead of scaled down from a larger programme.

Attritable by design isn't a slogan. It's an engineering constraint, applied from the first sketch.

Volaris is based in Queensland, with the Jäger's architecture finalised and sub-scale flight testing complete. The next phase is about proving the system in front of the people who need to see it work.

Advisor, Volaris Defence Technologies
Retired RAAF Warrant Officer, 15 years' service
F-111 radar & guidance systems technician
Aircrew: UH-1 gunner, CH-47/C-130 loadmaster & flight engineer
32 years commercial aviation — Cathay Pacific & Emirates
A380 Captain, Synthetic Flight Instructor & Examiner — Emirates

Volaris draws on advisory support from Mark MacDonald, a retired RAAF Warrant Officer whose fifteen years of service began as a radio technician on F-111 aircraft, maintaining radar and guidance systems, before moving into aircrew roles across rotary and fixed-wing platforms: gunner on the UH-1, then loadmaster and, later, flight engineer on the CH-47 and C-130.

That was followed by thirty-two years in commercial aviation with Cathay Pacific and Emirates, most recently as an A380 Captain and Synthetic Flight Instructor and Examiner, training and assessing other pilots on the fleet. His background extends into weapon systems and their operational use, and into defence procurement and doctrine, brought to Volaris in an advisory capacity.

Based

Queensland, Australia

Volaris is built in Queensland by design, not default. Sovereign capability means capability that exists inside Australia's own industrial base, not capability that's licensed, imported, or promised for later. Building here is part of the argument, not just the address.
