COBI 3038 IS-7 – Speed Build Review

Change language to: de_DE Deutsch

Since I already own the other models in the IS series, I naturally had to have this model, too. In this review I show the building and of course I will compare the tank with the other versions.

Manufacturer: Cobi
Set-Number: 3038
Theme: Military
Release: 2019
Parts: 650
Figures: 1
Age: 8
Building Time ca.: 2 Hours 55 Minutes

The name of the IS series was derived from the name of the dictator Joseph Stalin (Iossif Stalin). The heaviest tank ever made in the Soviet Union and there were only produced just 6 prototypes. Instead, the lighter T-10 was developed for series production.

Brick Quality

The high level of COBI is continued in this model. Everything fits together perfectly, making building a lot of fun. Except for a few single-colored contours, the entire label consists of stickers. However, this is the case with almost all models of the WoT series so that you can adapt your tank to that of the game.

Instruction Manual

Immediately after opening the instructions, numerous stickers jump towards us. Otherwise, it does not differ from other COBI instructions. Old steps are grayed out so that the new, colored ones can be carried out easily. After 3 construction phases and 128 construction steps, the beautiful model is finished.

The Building

We start this model again with the hull, which initially hardly gives the impression that a large tank is coming out. Plentiful plates and large bricks again ensure that we get a very stable basis. The basic structure of the side armor is built separately and then attached to the hull.

Then we start with the cladding with tiles. Only then do the front and rear come, which are also built separately and then attached. As with many models, the slope is realized via hinges. After the entire armor has been attached, it is the turn of the chains. The large chain links can be easily put together and roll super soft. You don’t need pressure and a smooth surface doesn’t hinder them.

Finally, it’s the turn of the mighty tower. You can quickly see that it is a post-war model. In contrast to the massive, tall tank models, both the entire substructure and the tower are very flat and rounded. Even with a hit, this increases the chance that the grenade will do little damage to the shell.

IS-2 vs. IS-3 vs. IS-7

As a successor to the IS-3, a direct comparison is of course obvious. The dimensions of the armored trough agree somewhat. Depending on the view, one or the other tank may appear larger. However, the tower of the IS-7 is significantly longer and a bit narrower. The tube of the new model clearly exceeds the old version. The old IS-2 looks even less bulky in comparison. If you put all 3 models side by side, you can see the development of the tank shape very nicely.


The new IS-7 is a very beautiful model that looks wonderful in the showcase. Thanks to its stability, it would also be suitable for playing. The construction is a lot of fun and easy to do. I did it without the stickers. Here I would have wished that at least the red star would have been printed.
