When the YEE is in driving mode, its wings would fold downwards, and small wheels along their outside edges would allow them to act as outriggers. The car could even carve into turns, by leaning towards one outrigger and away from the other. Speaking of turning, though... how would the thing be steered?
When it went into flight mode, the YEE’s two back wheels would swing forward and their rather stylin’ spokes would reveal themselves to be the propeller blades that they actually were. Pretty clever. Another question comes to mind, however: when the car was taking off and its outriggers folded upwards to become wings, wouldn’t it just fall down on the road? And likewise, how would it maintain take-off speed or hold its back end up when its wheels folded forward? Just asking.
