magniX, a frontrunner in electric aviation propulsion, has partnered with Robinson Helicopter Company (Robinson) to develop a fully electric demonstrator based on the popular R66 platform, aiming for its first flight in late 2026. The project will leverage magniX’s advanced electric powertrain, featuring its lightweight, high-speed HeliStorm engines designed for rotorcraft and its high-energy-density Samson batteries, renowned for their long cycle life.
magniX CEO Reed Macdonald highlighted company’s history of pioneering electric helicopter technology, including two ground-breaking electric Robinson R44 test flights and the world’s first piloted hydrogen-electric helicopter flight in March 2025. He emphasised the significance of deploying next-generation HeliStorm engines and Samson batteries for the R66 programme, calling it a step forward in transforming vertical lift aviation.
Robinson CEO David Smith noted that magniX’s expertise in electric propulsion and previous experience retrofitting the R44 made them the ideal partner for exploring alternative powerplant solutions. The collaboration aims to deliver “market-leading, zero-emission solutions” that meet diverse operational requirements, from utility and training to critical mission types.
With more than 1,500 R66 helicopters already in service and over 100 units sold annually, the electrification of this widely used platform is expected to significantly influence the vertical take-off and landing (VTOL) market. magniX Chief Technology Officer Riona Armesmith pointed out the cost, noise, and safety benefits of electric propulsion, emphasising its suitability for helicopters and the clear certification pathway for future electric rotorcraft. This project signals a major shift toward sustainable, zero-emission helicopter operations.
