Volz Servos Powers Quantum Systems’ Twister eVTOL with Customised Actuator Technology

The eVTOL market is accelerating as operators demand aircraft that combine vertical lift with efficient fixed‑wing cruise. Central to this evolution is the need for actuators that deliver pinpoint accuracy, rapid response, and aerospace‑grade reliability. Volz Servos, a long‑standing supplier of high‑performance servomotors, has leveraged its expertise to create a bespoke solution that meets these stringent requirements, positioning the company as a critical enabler of next‑generation autonomous aircraft.

Quantum Systems' Twister exemplifies the emerging class of compact, reconnaissance‑focused eVTOLs. Weighing just 4 kg, it can remain aloft for 90 minutes and travel up to 15 km, all while navigating GPS‑denied zones through fused visual and inertial data. By integrating ARINC 825, an aviation‑specific extension of the CAN bus, Volz’s DA‑15N servos provide deterministic timing, prioritisation, and fault‑tolerant communication—features essential for certification and mission safety. The servos directly actuate the wing flaps, ensuring smooth transitions between hover and forward flight, which is vital for the aircraft’s autonomous operation in confined 2 × 2 m launch spaces.

Beyond the technical merits, this partnership signals a broader shift in aerospace supply chains toward specialised, certified components. Reliable actuator technology reduces integration risk and accelerates time‑to‑market for ISR platforms, giving operators a competitive edge in rapid‑deployment scenarios. As regulatory bodies tighten standards for autonomous flight, manufacturers that embed certified protocols like ARINC 825 will likely dominate future procurement, reinforcing the strategic value of collaborations such as Volz and Quantum Systems.
