1. Unrivaled Power and Exceptional Thrust for Heavy-Lift Missions‌
This 550cc engine sets a new standard with 49.62 HP (37 kW), generating a massive 70kg of thrust at 100m altitude. This makes it the ultimate power source for the most demanding commercial UAV applications, enabling heavy payloads like advanced sensor suites or large delivery systems, ensuring your drone operates with power to spare for critical operations in filming, logistics, and industrial inspection.

‌2. Advanced Horizontally-Opposed 4-Cylinder Engine for Superior Balance and Smooth Operation‌
Featuring a sophisticated 4-cylinder, horizontally-opposed "boxer" layout, this engine provides perfect inherent balance. This design drastically reduces vibration compared to conventional engines, leading to smoother flight, enhanced stability for precision tasks, reduced stress on airframe components, and clearer data or imagery from onboard equipment.

‌3. Robust, Forged Construction for Professional Durability and Longevity‌
Engineered for relentless professional use, the engine incorporates a rugged forged 7-piece crankshaft and four diaphragm-type all-position carburetors. This premium construction ensures exceptional durability, impact resistance, and a long service life, guaranteeing reliability and minimizing downtime in challenging operational environments.

‌4. High-Efficiency Design with Optimized Fuel Consumption and Flexible Configuration‌
Achieving high power doesn't mean high waste. This engine maintains an efficient fuel consumption of 14L/h with a favorable 50:1 fuel-oil ratio, lowering operational costs. Its modular design, offering optional starters, generators, and exhaust adapters, allows for precise customization to meet your specific mission profile and power needs.

‌5. High-Altitude Performance and Reliable Solid-State Ignition‌
Maintaining strong performance where the air is thin is critical. This engine delivers 61.8kg of thrust even at 1,800 meters (5,900 ft), making it ideal for mountain surveying, high-altitude mapping, and search & rescue. The solid-state magneto ignition ensures quick, reliable starts and stable operation in diverse and cold weather conditions.
