Heart anticipates delivering the first ES-19 for commercial use by 2026. The first-generation aircraft will have a maximum range of up to 400 km (250 miles), using today's lithium-ion batteries. Range will increase as battery energy densities improve.
The core of the ES-19 is the electric propulsion system. In 2020, Heart demonstrated its first iteration of this electric propulsion system, consisting of a 400kW electric motor, an electric motor controller and a battery pack with an integrated BMS system – all with world-leading
There have been plenty of pre-orders of potential planes from startups. There have been pre-orders of supersonic passenger planes. Many companies have failed without delivering on planes that were pre-ordered.
