Product Description

The DLE222 is the flagship of DLE’s gasoline engine lineup, featuring a powerful four-cylinder configuration designed for extreme UAV missions, professional logistics platforms, and the largest RC aircraft. With a massive 222.5cc displacement and 21.5 HP output at 7500 RPM, this engine provides unmatched performance for heavy-lift operations and high-altitude applications.

Generating an incredible 51 kg of thrust at 100 meters altitude (and 44.6 kg at 1800 meters), the DLE222 delivers both raw power and smooth operation. Its 4-cylinder design ensures minimal vibration and consistent power delivery, while the robust ignition system and NGK CM6 spark plugs ensure reliability across diverse flight environments. Compatible with large propellers up to 34 inches, the DLE222 is built to exceed expectations in endurance, payload, and flight time.
