Powered by a four-cylinder Kawasaki engine, it will be used for airframe design flight testing prior to the installation of a hybrid powerplant.

[9] In November 2024, VoltAero inaugurated its final assembly facility and headquarters, marking a significant advancement towards the certification and production of its Cassia electric-hybrid aircraft series.
