This model released as premium model before. But I released this for free now. Hope you like it.
I remind you this is old files, so maybe its have some errors. You can improving while build it.
Unfortunately there are not colored templates, you can coloring yourself if you need to print them on white paper.
Overall this model is easy-medium, but some parts maybe hard, like joints.
So I think you should make a fixed joints. ^^'
