AirQ has officially introduced the lightest hybrid engine ever built for fixed-wing unmanned aerial vehicles, a breakthrough that pushes the limits of endurance, efficiency, and performance in autonomous aviation.
With a displacement of just 33 ccm and a total weight of only 2.8 kg (≈ 6.17 lb), this compact hybrid system delivers a powerful 2.1 kW output. But the real story goes far beyond the numbers.
Engineers at AirQ spent more than a year and a half refining the software alone, running countless simulations, validating stability models, and tuning every gram of performance. The result is an engine that is smaller, lighter, and more capable than anything in its class, built for missions where weight, reliability, and energy efficiency define success.
And the proof is already in the sky.
The hybrid engine has completed a continuous 6-hour flight, demonstrating consistency, safety, and fuel efficiency throughout the entire mission. Now, the team is preparing to push it even further in the upcoming endurance tests. This isn’t just another power unit.
It is a significant step forward in hybrid propulsion for unmanned aviation, fully designed, engineered, and tested in-house at AirQ. A new benchmark has been set.
