Well, based on small research, I just realized that this kit is the copy of 2005 Tamiya DKM TIRPITZ with some additional changes:

1. There's some parts to make this kit runs automatically by battery-powered, meanwhile the Tamiya is not.
2. The nameplate and stand is different.
3. The lower and upper hull is separated, meanwhile the Tamiya Tirpitz's hull is joined.
4. The manual books isn't so detail, compared to Tamiya's manual.
5. No Kriegsmarine's flag decal (Tamiya has it)

6. This kit has two lower hull options; full hull and waterline
