Rotron Rotary Engines

Rotron RT300 and RT600 EFI/HFE Rotary UAV Engines

The Rotron Rotary UAV Engine Line features a revolutionary single-motor design. The Wankel cycle engine is a 4-stroke rotary engine, making it smaller, more fuel efficient, more powerful and more reliable than other equivalent piston engines.

The revolutionary Rotron Rotary UAV engine is considerably smaller, lighter, and contains fewer moving parts than piston engines of equivalent power output. Every engine is fine-tuned to its optimum operating efficiency and safety levels before shipment. If your application requires a different power configuration but needs to keep the same package size, custom options are available.

All Rotron Rotary Engines Feature:

  • High power-to-weight ratio with increased efficiency
  • Compact package size allows greater fuel and payload flexibility for multi-mission capability
  • Fuel injection and ECU controlled altitude compensation fitted as standard
  • Higher endurance lifecycle
  • Available in pusher or tractor (puller) configurations, with either direct or reduction drive
