Neoptera Aero applied for its first patents for the eOpter concept in December 2017. Since then it has built and flown a sub-scale model of a design featuring a tail-sitting fuselage with eight propellers on tandem wings. As of November 2019, the privately-owned company was seeking funding to build and fly a half-scale model. It intends to certify the aircraft under the European Union Aviation Safety Agency's SC-VTOL special condition rules and hopes to achieve this with a four-seat version of the aircraft by the end of 2026.
