Overview
- The X1 demonstrator flew a piloted, all-electric 27-minute test that reached about 1,100 feet and delivered more than one megawatt of propulsion power.
- Heart reported the flight used roughly $5 of electricity, a figure that measures raw energy consumed and does not include crew, maintenance, battery lifecycle or other operating costs.
- The X1 is a full‑scale technology demonstrator for the planned 30-seat ES-30; Heart says it will use X1 flight data to refine systems as it builds a pre‑production ES-30 in Los Angeles.
- Heart has scheduled flight testing of the first pre‑production ES-30 for 2028 and is targeting commercial entry in 2031, goals the company describes as targets that remain subject to technical and certification risk.
- Because current battery energy density limits all‑electric range to about 124–125 miles, Heart plans a hybrid ES-30 with a combustion range‑extender to reach roughly 497–500 miles, and major carriers including United, Air Canada and JSX have publicly committed to the program.
