This is a pretty awesome kit. As with all Meng kits, the fit of the parts is excellent, the instructions are clear and easy to follow and there is no flash on any of the parts. For being 1/35 scale, this bulldozer is actually pretty big and is full of a lot of detail. One of the first few steps has you build the ripper blade in the back which raises and lowers as long as it isn't glued together. While it isn't a lot of movement, it makes for a nice touch as well as all of the hydraulic hoses that go to it. The front blade also has movement up and down. The cab is pretty well detailed on the inside and comes with both clear and a bluish-green tinted glass. The most difficult part to building this kit are the tracks and it's only because of how they are put together if you want to keep them workable. This kit would make a great addition to the Hobby Boss M1070 HET. I would highly recommend this to anyone as Meng kits are really easy to put together and practically build themselves.
