magniX Electric Engine Range

magniX electric engines offer class-leading torque density, power-to-weight, and safety features, with reduced maintenance requirements and more time in service. All magniX electric engines can be integrated as part of a full magniX powertrain solution or purchased as a standalone product. Our high speed engines can also perform as generators.

Spec Sheet

HeliStorm is designed around the requirements of electric helicopters, offering lower weight than a typical turbine engine, improved efficiency, reduced operating costs, and straightforward integration with existing rotorcraft transmission systems.

magniX is partnering with Robinson Helicopter Company on an electric version of the popular R66 model, powered by HeliStorm.

Spec Sheet

The lightest and most powerful electric engine in its class, magniAIR is bringing next-generation electric propulsion to experimental aircraft, flight trainers, eVTOLs, and UAVs. At a time when flight enthusiasts and training schools have been squeezed by rising costs, magniAIR’s low cost of operation and reliability promise to democratize small aircraft.

magniX is integrating magniAIR as part of a full magniX powertrain into a Van’s RV-10, with the engine available to purchase from 2027. Register your interest →
