Heart replaced its ES-30 design with the ES-36: six more seats and 20% more payload at the same take-off weight, two series-hybrid engines instead of four. Batteries give 200 km of range, turbogenerators 1,200 km. JSX signed for 50 aircraft plus rights to 50 more; first flight is targeted for the second half of 2028 and service for 2031.
