MagniX Helistorm electric engine for helicopters
MagniX is developing Helistorm electric engines specifically for helicopters, based on technology already used for its Magni650 electric propulsion units for fixed-wing aircraft.

Propulsion pioneer MagniX is developing a new family of electric engines specifically designed for helicopters. This week, the U.S. company is going public with its response to demand for faster rotor speed motors with between 6,000 and 7,000 rpm, compared to 1,900- to 2,500-rpm powertrains it is already developing for other applications.

MagniX is working the helicopter motors, which it announced on Monday at Verticon 2025, with a view to be ready to start tests next year. It is aiming to have hardware, which will be integrated with the company's Samson batteries with an energy density of up to 300 Watt hours per kilogram, delivered to early customers in 2026.
