This concept idea happened while brainstorming for Trasgo project, but it was interesting enough to be further explored and defined.
The initial configuration started with the idea of connecting the wing and tail surfaces to take advantage of some aerodynamic effects. However, the interesting part was the position of the engine right in the center of the aircraft. This allowed for smooth maneuvers since the force from the engine and propeller was aligned with the center of mass.
Connecting the wing and tail surfaces lead to a big wing surface overall that opened the possibility of using solar power like many soaring UAVs already do. And the closed rhombus geometry was perfect to integrate a big antenna for communications.
All these characteristics aligned with the mission of a pseudo satellite that can soar over a specific place for a long time.
