I believe the ultimate reply would be “as many as are needed”. Sometimes the kit might require more or less track links compared to the real thing, to establish the correct look (no sag, some sag, lots of sag).
Some tracks are tricky, like certain Tiger II tracks that have alternating links. You have to have an even number of links to properly connect the ends.
That’s why I like metal tracks for the “saggy” tanks. The glue together plastic tracks can be a bit of a gamble to get everything looking right.
No,I believe it’s still good to have a starting point in mind,that’s why I googled the question.The answer I found most was 85-87,so I will construct my run 1-2 links short,fix them to the tank,and see where I’m at,then add or subtract a link or two as needed.
So for someone to answer me by saying, “as much as needed”,I would consider that answer as no help at all,I need a number to work with.Im aware of aii the reasons why an exact number may not be possible,especially when building a small plastic model.I like metal tracks too,but kit included MT’s are a free alternative that look good too when I’m done with them,and don’t add $40-50 to every build that I do.
