Yes I do understand you are just trying to have some fun running your tank in the snow. Nothing wrong with that,i tried it my self a couple of times without much success as they do not like 4 inches of soft snow.Mabe on snow with a frozen crust they may work great,or at least be able to go more than a foot or two without getting stuck.

Now myself I don't get to concerned with scale when it comes to models.I'm not a real tank operator and have never been in or on one of them.But I have worked with and around cats and owned my own cat over the years and to me a tracked vehicle is a tracked vehicle.They are all designed to do certin things but if they have tracks there are traits that go from one to the other that to me are a given.

Now in real life like I said I'm not a tank operator,but would think a 50 to 70 ton tank would not do very well in snow four feet or more deep.Now a cat with a blade you can keep pushing it off to the side and build a road or trail and continue on.Take that blade off and see how far you are going to go........ Most tracked snow vehicles have two things that are important to their function being weight and width of tracks.

P.S. I guess one thing that would make a difference would be wider tracks with cleets,more like on a cat.
