Everett, WA, U.S., - March 10, 2025  -   magniX , the company powering the electric aviation revolution, today announced the launch of a new range of lightweight, high-speed electric engines. HeliStorm engines are ideally suited for helicopters, from light single engine to larger hybrid-electric twin engine rotorcraft, as well as for airborne power generation.

Combined with magniX’s Samson batteries, HeliStorm engines enable the company to offer a complete electric solution for rotorcraft. The first engine in the range provides peak power of 330kW at a weight of just 75 kg.

Key features of HeliStorm engines for rotorcraft include:

• • Operating speed of 6,000-7,000 RPM

   

  Launching the Electric Helicopter Age

  With this new range of engines, magniX is leveraging its years of experience across many flight test programs, including two separate integrations with Robinson R44 helicopters. The first electric Robinson R44 helicopter powered by a magniX motor flew on 4 June 2022 at the Los Alamitos Army Airfield in California. This was a significant milestone in the development of electric aviation and subsequent tests went on to deliver the world’s first point-to-point flight of an electric helicopter.

   

  “The helicopter market represents a tremendous opportunity for magniX, as the strengths of our technology align well with the market need,” said Reed Macdonald, CEO of magniX. “magniX’s HeliStorm engines expand upon our existing world leading capabilities and deliver a step change in performance, reliability, and value for our customers. We look forward to bringing our innovative technology to another segment of the aviation industry.”

   

  “Our HeliStorm engines are designed for the specific demands of vertical lift applications and will give magniX the ability to electrify a wider range of platforms,” said Riona Armesmith, magniX’s Chief Technology Officer. “This new product line enables us to build on our unparallelled performance of powering different aircraft with our industry leading electric powertrains.”

   

  “magniX has a proven track record when it comes to powering our R44 with their electric motors,” said David Smith, CEO of Robinson Helicopters. “Robinson is supportive of magniX’s HeliStorm electric engine range and we look forward to continuing our collaborative efforts to deliver market leading sustainable helicopters.”
