This is quite the model! I was amazed at the detail as there is Rods, Pistons, valves etc. to assemble. This was for my adult grandson and should be interesting to see how well he does.
Looks good, didn't cost much, works just fine.
Husband loved putting this together. Works great
Right out of the box it works beautifully! I bought it for my father and the first night after I gave it to him, he and my brother spent most on the night trying to figure out how it work. My dad really loves it.
