Rotron Rotary UAV Engines

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

Carbon Air Intake

Designed, manufactured and stringently tested in-house, our carbon-effect intake silencers reduce mechanical engine noise and air intake pulse wave resonance significantly. Aerodynamically shaped to increase airflow into the engine, this design is DULV certified.

High Performance Engine

The revolutionary Rotron Rotary UAV engine is considerably smaller, lighter, and contains fewer moving parts than piston engines of equivalent power output. With no crankshaft, connecting rods or valves. The design eliminates the most highly stressed and failure prone parts of piston engines giving the Rotron engine high reliability, a smoother application of power, and a high power to weight ratio. All components are manufactured and assembled in-house with the highest level of quality control. Every engine is fine-tuned to its optimum operating efficiency and safety levels before shipment.

Electric Engine Start

High energy 12 volt starter motor built to industry standards for proven reliability and performance. The integral starter battery compartment and electronics case ensures all wiring and components are protected.

Propeller Design & Manufacturing

Low Noise Propellers for Unmanned Aerial Vehicles. The NW UAV exclusive Elippse Design produces Low Noise Propellers for Unmanned Aerial Vehicles. Availalble as fixed-pitch propellers and variable-pitch propeller blades. Manufactured in various blade configurations.
