rex-b 300

CHOOSE FREEDOM.

unrivaled power to weight ratio

MAX POWER

Lightness

At the core of the REX-B 300 lies the patented 1Stroke® technology which has been meticulously developed from the ground up to function as a superior range extender solution for UAVs.

The REX-B 300 leverages this breakthrough technology to achieve twice as many power events per cycle compared to traditional two-stroke engines, leading to the highest power-to-weight ratio in the market, setting a new standard for efficiency and performance.

NO VIBRATION

Equilibrium

INNengine technology is the first one to offer an engine with no counterbalancing measures required.

It is born just perfectly balanced.

An engine with total 1st and 2nd order equilibrium, resulting in a 0-Vibrations operation throughout the entire RPM range.

HEAVY DUTY

Dependable

The 1Stroke® engine technology enhances the compactness of the REX-B 300, allowing for an overpowered design that optimizes efficiency without sacrificing performance.

This approach, combined with a dedicated lubrication system and a hybrid air/oil cooling system, ensures the REX-B 300 is a heavy duty machine, fully equipped to handle the most demanding industrial and military applications.

The REX-B 300 comes in three different configurations, designed for a variety of UAVs.
These powertrains are versatile, highly efficient, and provide reliable performance, supporting both VTOL and HTOL capabilities for smooth operations.

FULL ice

50HP

Whether VTOL or HTOL, the REX-B 300 is the ideal Ultralight Powertrain for direct drive needs up to 50Hp and electrical loads from 500W to 1500W.

Designed for peak efficiency and reliability, it ensures superior performance in the most demanding conditions.

HYBRID

   

The REX-B 300 excels in modern UAV setups, supporting Electrical VTOL motors during take off.

It recharges a compact battery during flight and directly drives the propeller during fixed-wing cruise operation for consistent performance throughout.

FULL rex

18KW

Fly electrical for hours and not minutes without payload compromise: the REX-B in Range Extender mode recharges UAV batteries on the fly up to 18kW,
enhancing efficiency and eliminating vibration.

BE AUTONOMOUS

Power Focused Engineering

Our engines deliver unmatched efficiency and torque for peak performance.

We utilize aerospace-grade aluminum alloys such as 7075-T6 and 6082-T6, along with high-precision CNC machining and top-quality treatments like hard anodizing, Nikasil, or nitriding.

These techniques enhance operational output and maximize performance, ensuring exceptional durability and resilience in demanding applications.
