FQ-550 Powertrain Surpasses 5,000 Hours of Verified Flight

FQ Engine announces that the FQ-550 aviation powertrain has now surpassed 5,000 hours of verified flight time in field service. The milestone reflects real-world operation across long-endurance industrial drones and light sport aircraft, where the horizontally opposed four-cylinder engine delivers 37 kW of reliable thrust. Every engine is dynamometer-tested and flight-verified before delivery, and this accumulated field data continues to guide our reliability improvements. We thank our customers and partners for their trust, and look forward to supporting more missions worldwide.
