The original review can be found here.
The instructions are not so clear as they look at the first sight, so there are errors about the colors to use – for the yellow they indicate a green instead! There are some sub assemblies that should not be build as indicated, (parts A32 and A34). The tracks are not easy to work, and a perfect fit required cutting off some of the sprocket wheel teeth.
The build is going to be published in SMMI magazine.
