Remote-controlled Soviet KV-1 and KV-2 heavy tanks roll out in defense of the Motherland [Video]

Polish LEGO builder Sariel is famous for his huge LEGO models that incorporate LEGO Technic and Power Functions elements for working features without sacrificing details or the overall look of the model. His recent MAZ-535 artillery truck was no exception, and it reminded us that we had overlooked his fantastic KV-1 heavy tank and KV-2 heavy artillery tank. I’ve built LEGO KV-1 and KV-2 tanks myself, so I have an appreciation for the challenging angles of these early WW2 Soviet tanks.

Sariel’s models always feature a variety of working functions, and these tanks are no different. The turret rotates, while the gun elevates and depresses. Naturally, the tanks move forward on tracks with full suspension. Montage photos and a video featuring several of the tanks aside, Sariel has actually built just one tank hull and chassis with a pair of turrets that he can swap out. This makes sense, because the KV-2’s enormous artillery gun turret sat on an existing KV-1 heavy tank hull.

What’s a “clip ejection door?” you ask? Read more about this model’s features on Sariel’s blog and you can watch the tanks in action in this video to see what the KV-2 can do with its turret.
