I am considering ordering this to assemble and i was hoping i could get a few questions answered about it here. 1. I have assembled regular zoids ( both wind up and battery powered) and blox type zoids, how much more difficult is the High end master mold zoids to assemble? 2. its my understanding glue and paint are not needed for assembly but might be useful at times, is this true? 3. are there any known problems with this kit?
