Description
The DE120 is a lightweight yet powerful 120cc twin-cylinder 2-stroke gasoline engine designed for medium-class UAVs. Delivering up to 26.5 kg thrust at 100 m altitude and excellent high-altitude capability of 23.5 kg thrust at 1800 m, the DE120 is optimized for professional applications such as logistics delivery, aerial mapping, inspection, and surveillance.
With a weight of only 3.05 kg, it supports UAVs up to 60 kg MTOW, offering one of the best thrust-to-weight ratios in the 120cc category. Its three-bearing crankshaft ensures smooth power delivery and extended durability, making it a top choice for drone manufacturers worldwide.
