See full text

An improved aerobatic aircraft design having a first engine located in the nose portion of the fuselage and a second engine located in the tail portion of the fuselage. The thrust components of both the first and second engines are coaxial along the long axis of the fuselage. Both engines can individually provide sufficient power for the aircraft to takeoff, maintain altitude, and/or land.
