Klingon D7 Battlecruiser

I received this model as a present. I wasn't sure at first what the differences were between a K'tinga and a D7. It seems most of the difference is in the details and colors, even though there are a few places on the ship where the design is a bit different. As for this model, the molds seem to be pretty old and the connecting points to the trees are thick, which makes it difficult to get the parts of without damaging them. There are also quite a few problems with fit, like the inserts in the front section leave a gap, the caps on the back of the engine nacelles do not fit right. The construction of the upraised area on the main hull of the ship has a lot of problems with fit. I find the instructions were not so good, and it showed absolutely no painting guide. I am not satisfied with the production of this model.
