Flieger magazine reports, “Piper Deutschland AG has announced a strategic investment in MD Aircraft GmbH . The goal of the collaboration is to advance the development and production of the all-electric regional aircraft MDA1 eViator.” (Note: based on later reporting, the power bays may be incorporated into the lower part of the fuselage.  The blog will attempt to gain verification of this.) Signed on September 19, 2025, the agreement “is intended to mark the start of a new chapter in aviation for Piper – with a focus on innovation and environmental sustainabilit,” according to Flieger. Providing MD the financial stability of Piper’s funding and for Piper the planned design for a twin-motored commuter liner in the size and performance range familiar to established Piper customers, the compact should be beneficial to both companies. The MDA1 Aircraft An “all-electric short-haul aircraft with a range of up to 400 kilometers (248 miles),” The MDA1 should suit the needs of most regional commuter lines internationally. We wrote …

Whisper Aero – Ultralight to Heavy

Whisper Aero, Mark Moore’s startup in Crossville, Tennessee, fields devices to move air, ranging from leaf blowers to fairly large airplanes.  The company recently showed a lineup of three aircraft, starting with a dual-motor powered flying wing hang glider to a nine-passenger silent medium-range carrier.  Each benefits from the quiet propulsion system developed by Moore and his team. The Whisper Lineup Whisper Aero plans a range of craft from a single-seat ultralight sailplane to a small lightplane-size cargo carrier to a nine-passenger transport.  All are capable of flying autonomously, and all will be powered by from two to 30 Whisper Aero eQ250 propulsors, each capable of 80 pounds of thrust.  In this video, Manfred Ruhmer, seven-time world Class 2 ultralight soaring champion among other honors, shows off his Aeriane Swift 3, taken aloft by an Eck-Geiger electric motor, and then elevated by its light weight and Manfred’s piloting skills.  It will be fascinating to see how The ship will perform …

From Ganged Motors to Wright’s Two MegaWatts

Twelve years ago, your editor gave his first talk at an electric aircraft symposium.  Dr. Brien Seeley asked that he include all motors up to 100 kilowatts in his talk – at that time a rarity.  Designers often had to “gang” small motors to drive a single propeller to obtain the necessary power.  Now, Wright Electric has announced its plans to develop motors (and associated equipment) in the 500 kilowatt to 20 megawatt range.  Motors of those sizes are still under development, but Wright claims to have tested and demonstrated “a megawatt-class, high performance inverter,” according to Green Car Congress. Jeff Engler is getting recognized for his vision.  Here he give his virtual elevator speech at the Davos, World Economic Forum. His positive and yet measured approach seems to gain acceptance for that vision. Demonstrated Performance? Aiming for some audacious levels of performance, Wright’s inverter could hit these metrics: “99.5% efficiency –a 6x improvement in heat loss over current in-production …

Ampaire Flies Hybrid Test Bed

Ampaire, a tech startup based in California, announces, “Our mission is to be the world’s most trusted developer of practical, compelling electric aircraft from short-haul cargo to supersonic passenger transport.”  They also claim to have demonstrated the “highest-capacity electric aircraft ever flown” last Thursday, June 5th at Camarillo, California.  The company hopes to “have regular commercial service for passengers and cargo as soon as 2021.” Using a Cessna 337 Skymaster was a canny move for the young firm, giving them ample weight-carrying ability to have a petrol engine in the nose and a dual-Emrax motor system behind the cabin and between the twin tail booms. The push-pull arrangement adds to engine-out safety with no assymetrical thrust as on a conventional light twin.  The Skymaster’s six-passenger cabin will enable profitable flights for charter work.  A standard 337 has an empty weight of 2,655 pounds and a payload of 1,745 pounds for a gross weight of 4,400 pounds. With four to six …
