The shape matches its real world counterpart almost perfectly. The engine looks great with its eight-sided shape, but the rear part of fuselage, the the arc of the wings are all perfect. The color choice is a bit unusual, it seems to be an air racer, but the shape makes it very clear that the basis is a war machine.
Amongst the images there are more war-like creations too. This one is another legendary aircraft with a radial engine: an F4U Corsair fully armed:
To me these models with all their perfection seem almost a little bit "too synthetic": it feels like they want to hide their studs and I start to have doubts if they are made of LEGO bricks. But the finish is perfect: the body, the wing of the Corsair are all a perfect copy of the original. It is no coincidence that a the newest models ended up on Brothers Brick.
As an amateur builder I get very curious too: how? What is under the skin? Ok, I have some ideas about the wing, but how is the engine built? Fortunately there are quite strong hints amongst the photos. Voila:
The brilliant part is the 4-studded bricks in the front that are rotated in 45 degrees to form a skeleton for the 8-sided shape. The rear part is also very interesting as it is basically a skin held together by bricks with studs on the side. Take a look at the canopy too: the front part is held in place by a gray minifig hand.
Feels like no matter how many aircraft I build as an amateur I will never get to this level. No matter how much I tease my brain I will not be able to build so freely in all dimensions, and not stick to plates and bricks. Congratulations, Sydag, keep up the good work!
