X1 Completes First Electric Flight
Heart Aerospace has flown its X1 demonstrator for the first time, completing a 27-minute piloted test flight at Plattsburgh International Airport in New York on August 12, 2026.
The company says the X1 is the largest battery-electric aircraft ever flown. The aircraft has a 106-foot wingspan, measures 76 feet from nose to tail, and weighed more than 25,000 pounds at takeoff.
During the flight, the aircraft reached 1,100 feet above ground level. Its all-electric propulsion system delivered more than one megawatt of power, showing that the test was not a small-scale lab demonstration but a full-size aircraft flight.
Why it matters: Electric aviation has often been tested on smaller aircraft, but X1 brings battery-powered flight to a much larger scale.
Test Flight Covered Basic Aircraft Handling
The test profile included taxiing, takeoff, climbing, manoeuvring and landing. Heart conducted the flight under an FAA Special Airworthiness Certificate in the Experimental Category.
That certificate allows experimental aircraft to fly under controlled conditions while developers gather data. For Heart, the first flight was designed to prove that its battery-electric system can operate at a scale relevant to future commercial regional aircraft.
Heart also shared footage of the flight on X and said the aircraft used around $5 worth of electricity during the mission. That figure refers only to electricity used in the test flight, not the full operating cost of a future commercial service.
| Feature | X1 figure | Why it matters |
| First flight | August 12, 2026 | Marks the start of flight testing |
| Mission profile | 27 minutes; 1,100 ft AGL | Shows controlled piloted operation |
| Aircraft size | 106 ft wingspan; 76 ft length | Places X1 near regional-aircraft scale |
| Takeoff weight | 25,000+ lb | Shows large battery-electric aircraft mass |
| Power output | 1+ MW | Demonstrates high-power electric propulsion |
Cost note: The $5 electricity figure should not be read as total flight cost because crew, maintenance, airport charges and certification costs are separate.
X1 Is A Step Toward The ES-30
The X1 is not meant to become a passenger aircraft. It is a full-scale demonstrator that helps Heart Aerospace collect data for the ES-30, its planned 30-seat regional aircraft.
Unlike the fully electric X1, the ES-30 is planned as a hybrid-electric aircraft. Heart lists an all-electric range of 200 km, a hybrid range of up to 800 km, and a charging time of around 30 minutes.
The company expects flight testing of its first pre-production ES-30 to begin in 2028. It is targeting certification and commercial service entry in 2031, with United Airlines, Air Canada and JSX among airlines that have made commitments to the program.
What Comes Next For Electric Regional Flight
The first X1 flight does not mean electric passenger service is ready now. Battery weight, certification, charging infrastructure, reliability and operating economics still need to be proven before airlines can use such aircraft commercially.
Still, the X1 flight gives Heart Aerospace a working platform for testing systems at a meaningful size. Each flight can help engineers understand thermal performance, battery behaviour, power delivery, handling and maintenance needs.
If the ES-30 program stays on schedule, the next major milestone will be pre-production flight testing in 2028. That stage will show whether the technology can move from a demonstrator into an aircraft closer to airline use.
Outlook: X1 proves a large battery-electric aircraft can fly, but commercial success will depend on certification, range, reliability and airline economics.
