Just an experiment in sustainable invertable flight. The primary wings are symmetric. Use the VTOL slider to adjust the angle of attack. It's pretty tricky, but it can be landed and taken off either right-side up or upside-down. Touchdown should be made at around 150 mph as straight as possible. 25% throttle on approach should be sufficient. Avoid excessive AOA at low speeds, as it reduces stability. Take care to swap pitch inputs when inverted.

    @Treadmill103 Yes thank you. Having the ability to have equal upward lift for both orientations was central to this concept.
