This is possibly the most incredible thing I have ever seen made in lego. When I first clicked on it I though "oh cool, a half decent blackbird", them I saw the functions and though "that is amazing". Love how you captured the movement and shape perfectly. BTW this is one of my favorite aircraft of all time.
SR-71 is my favorite aircraft and I have hardly seen a handful of nice Blackbird mocs.
Yours is really stunning and I like the wing texture, the cockpit and how it fits the minifig scale. Although I think the engines seem to be a little slim while the flaps are a bit oversized this is one of the best SR-71 mocs I've seen and definitely the best one of its scale.
+It really shines because of the joystick-pod-thingy and power functions.
Just wow! I didn't expect a 'system' style MOC from you, and I was right not to expect it! The Technic arm thingy functions are an engineering marvel. It's really playable too, just how Technic should be. 10/10, awesome work : )
