Product Description

The DLE170 electric start version offers a high-performance propulsion system for industrial UAVs, VTOLs, and RC aircraft. It is based on DLE’s powerful 170cc twin-cylinder engine, enhanced with a planetary gear electric starter to support remote and autonomous ignition.

This version removes the onboard generator to reduce weight and mechanical complexity, making it ideal for aircraft that do not require in-flight electrical output. The electric starter ensures quick, smooth, and reliable engine startup with low vibration and high torque performance.

Delivering 17.5 horsepower at 7500 RPM, and supporting propellers up to 32 inches, the DLE170 is built for endurance, payload capacity, and operational efficiency in demanding aerial applications.
