The SR-71 Blackbird was a famous CIA spy plane—the perfect choice for Lego builder Sariel who has been longing to build an aircraft from blocks for a while. The plane is legendary so Sariel really wanted to do it justice. It all started with a basic frame:
The model was built around a simple Technic frame running through all the central hull. The frame was reinforced around the model’s center of gravity, where a mounting point for the control mast was located. Since there are no wing-shaped tiles by LEGO, only regular plates, I decided to build the winds sideways to make them smooth. That resulted in all leading edges being a whole 1 stud thick, but it allowed to model the plane’s silhouette reasonably well, and to include bricks with grille to recreate the corrugated “wing skin”. Each wing consisted of two parts with the engine in the middle, and the whole wing was attached to the hull at 5 points. I have put a lot of effort into making the model structurally solid despite its size and thin surfaces, so most connections used Technic pins, and some used axles.
It’s pretty technical, but you can tell from the excerpt just how much time and planning went into creating this amazing craft. The brick Blackbird features “motorized elevons, rotating and illuminated engines, motorized control mast and custom stickers.” It’s over 2 feet long and crazy impressive.
