This is the Otto Celera 500L. The plane will perform the role of a business and utility aircraft. The startup company that designed it wants the Otto Celera 500L to have a good fuel economy and lower operating costs compared to other competitors on the market. The aircraft has one five-blade propeller in a pusher configuration (meaning it is behind the engine) and has laminar shapes for the wings, tail sections, and fuselage. As of August 2020, Otto Aviation Group has conducted 31 test flights. They plan to release it between 2023-and 2025 for $4.5-5 million.
