120cc four-cylinder two-stroke gasoline UAV engine delivering unmatched performance, precision, and reliability. Launched in May 2020, it stands as DLE’s smallest-displacement four-cylinder powerhouse, engineered specifically for professional UAVs, fixed-wing aircraft, and large-scale aeromodel applications that demand high output with smooth stability.

With an impressive 12 horsepower at 7500 RPM, the DLE120T4 ensures powerful, efficient, and vibration-balanced performance. The engine’s four-cylinder configuration provides superior throttle response, enhanced cooling, and optimized torque delivery — making it ideal for heavy-lift drones, long-endurance flight platforms, and hybrid propulsion UAVs.

Built using precision-machined aluminum components and advanced internal balancing, the DLE120T4 guarantees durability under extended operational conditions. It uses clean 92# or higher unleaded gasoline at a 30:1 fuel-to-oil ratio for maximum efficiency and reduced carbon buildup.
