Rotron Rotary UAV Engines

Smaller. Lighter. More fuel efficient.

Rotron Rotary UAV Engines are 4-stroke Wankel cycle rotary engines that are considerably smaller, lighter, and contain fewer moving parts than piston engines of equivalent power output. The engines are fine-tuned to optimum operating efficiency and feature high endurance and power-to-weight ratios. Fuel injection and ECU-controlled altitude compensation are fitted as standard.

Seven standard configurations are available, with custom configurations available on request.
