Just built a Lego stealth fighter/ drone.
It does need a little imagination to smoothen the edges, etc., bear with me on that…
But that said, have a look and let me know what you think.
Image above: Side-view. Completely collapsed for hangar/storage
Image above: Wings fully extended (it folds at two points, one, the grey section mid-wing, and the other, at the edge of the body)
Image above : Top view. The Forward Swept Wing (FSW) & delta canard design, similar to the Sukhoi-47
Notice 4 jet engines (2 running), and stealth cover on the sides, to minimize heat signature in-flight
Image above: The wings also swivel at a point just off the main body. This dramatically improves Angle-of-Attack (AOA).
